I've actually done a survey of ZFS articles recently and I found a number that were very interesting:
For a detailed comparison of various different configurations specific to the Thumper, see
<http://blogs.sun.com/relling/entry/zfs_raid_recommendations_space_performance>.
I particularly like his calculations comparing the IOPs performance of a 73GB 2.5" Seagate Saviio SAS drive against a 750GB 3.5" Seagate Barracude SATA drive.
There's also a link to <http://blogs.sun.com/relling/entry/zfs_raid_recommendations_space_performance1> which has the "all-in" version of the charts.
Then, for the specific application of NFS on ZFS, I found the page at <http://developers.sun.com/solaris/articles/nfs_zfs.html> which talks about using NFS on ZFS.
And the ZFS Best Practices wiki at <http://www.solarisinternals.com/wiki/index.php/ZFS_Best_Practices_Guide> links to an interesting page at <http://blogs.sun.com/roch/category/ZFS> which has all sorts of other interesting stuff, which I believe includes a way of calculating how you should size your zpools and your RAID-Z groups to achieve a given IOPs rate.
The "ZFS and Database Recommendations" page in the ZFS Best Practices wiki also has some recent tips regarding the use of ztune for setting prefetches and concurrent I/O values. There's also a ZFS Storage Pools Recommendations section, which might be interesting. I also noted a mention of Sun StorageTek Availability Suite (AVS), which might or might not be useful in terms of volume replication, point-in-time snapshots, or even continuous data replication. Or, if you want to avoid AVS, you might be able to play around with ZFS send & receive, as Mark Round does at <http://www.markround.com/archives/38-ZFS-Replication.html#extended>.
Eric Kustarz has some interesting ZFS benchmarking & tuning tips on his page at <http://blogs.sun.com/erickustarz/category/ZFS>, including links to DTrace tools to help you look deeply into the ZFS code and see where it's spending all its time, and how you can look at and tune vq_max_pending, etc....
I also found an interesting page on Lustre, ZFS, and Linux at <http://liquidat.wordpress.com/2007/07/17/lustre-runs-zfs-on-linux/>.
Special Presentation. For the January meeting we will have a presentation by Dr. Dominique Heger from Fortuitous Technologies
in Austin on filesystems that can be used in clusters.
The following is his abstract of the talk:
Traditional, local file systems support a persistent name space. A local file system views devices as being locally attached, the devices are not shared, and hence there is no need in the file system design to enforce device- sharing semantics. Instead, the focus is on aggressively caching and aggregating file system operations to improve performance by economizing on the number of actual disk accesses required for each file system operation. Newer networking technologies allow multiple machines (nodes) to share storage devices. IBMs General Parallel File System (GPFS) or Red Hats Global File System are representing distributed file system technologies that are taking a shared, network-attached storage approach. These file systems are built on the premise that a shared disk file system has to exist within the context of a cluster infrastructure, and has to provide proper error handling and recovery, as well as the best performance possible (performance, availability, and scalability features are key requirements).
The goal of this presentation is to elaborate on the terminology's surrounding the file systems that are being used in a Linux
cluster based environment. Some of the terms actually overlap, which may result in misconceptions and confusion on the user site,
an issue that is addressed in this talk. Further, this presentation discusses the classification of some the applications that may
be executed on a Linux cluster. To illustrate cluster file system technology, IBMs GPFS and Red Hats GFS file system are introduced
in more detail. The last part of the presentation briefly focuses on Sun Microsystems ZFS file system. While ZFS today is considered
a local file system solution, some of the features embedded in the design have the potential to revolutionize the file system industry.

I've actually done a survey of ZFS articles recently and I found a number that were very interesting:
For a detailed comparison of various different configurations specific to the Thumper, see
<http://blogs.sun.com/relling/entry/zfs_raid_recommendations_space_performance>.
I particularly like his calculations comparing the IOPs performance of a 73GB 2.5" Seagate Saviio SAS drive against a 750GB 3.5" Seagate Barracude SATA drive.
There's also a link to <http://blogs.sun.com/relling/entry/zfs_raid_recommendations_space_performance1> which has the "all-in" version of the charts.
Then, for the specific application of NFS on ZFS, I found the page at <http://developers.sun.com/solaris/articles/nfs_zfs.html> which talks about using NFS on ZFS.
And the ZFS Best Practices wiki at <http://www.solarisinternals.com/wiki/index.php/ZFS_Best_Practices_Guide> links to an interesting page at <http://blogs.sun.com/roch/category/ZFS> which has all sorts of other interesting stuff, which I believe includes a way of calculating how you should size your zpools and your RAID-Z groups to achieve a given IOPs rate.
The "ZFS and Database Recommendations" page in the ZFS Best Practices wiki also has some recent tips regarding the use of ztune for setting prefetches and concurrent I/O values. There's also a ZFS Storage Pools Recommendations section, which might be interesting. I also noted a mention of Sun StorageTek Availability Suite (AVS), which might or might not be useful in terms of volume replication, point-in-time snapshots, or even continuous data replication. Or, if you want to avoid AVS, you might be able to play around with ZFS send & receive, as Mark Round does at <http://www.markround.com/archives/38-ZFS-Replication.html#extended>.
Eric Kustarz has some interesting ZFS benchmarking & tuning tips on his page at <http://blogs.sun.com/erickustarz/category/ZFS>, including links to DTrace tools to help you look deeply into the ZFS code and see where it's spending all its time, and how you can look at and tune vq_max_pending, etc....

Special Presentation. For the January meeting we will have a presentation by Dr. Dominique Heger from Fortuitous Technologies
in Austin on filesystems that can be used in clusters.
The following is his abstract of the talk:
Traditional, local file systems support a persistent name space. A local file system views devices as being locally attached, the devices are not shared, and hence there is no need in the file system design to enforce device- sharing semantics. Instead, the focus is on aggressively caching and aggregating file system operations to improve performance by economizing on the number of actual disk accesses required for each file system operation. Newer networking technologies allow multiple machines (nodes) to share storage devices. IBMs General Parallel File System (GPFS) or Red Hats Global File System are representing distributed file system technologies that are taking a shared, network-attached storage approach. These file systems are built on the premise that a shared disk file system has to exist within the context of a cluster infrastructure, and has to provide proper error handling and recovery, as well as the best performance possible (performance, availability, and scalability features are key requirements).
The goal of this presentation is to elaborate on the terminology's surrounding the file systems that are being used in a Linux
cluster based environment. Some of the terms actually overlap, which may result in misconceptions and confusion on the user site,
an issue that is addressed in this talk. Further, this presentation discusses the classification of some the applications that may
be executed on a Linux cluster. To illustrate cluster file system technology, IBMs GPFS and Red Hats GFS file system are introduced
in more detail. The last part of the presentation briefly focuses on Sun Microsystems ZFS file system. While ZFS today is considered
a local file system solution, some of the features embedded in the design have the potential to revolutionize the file system industry.
| Growing, Shrinking File Systems with LVMUnder Construction | ||||
| Logical volumes can be reduced in size as well as increased. However, it is very important to remember to reduce the size of the file system or whatever is residing in the volume before shrinking the volume itself, otherwise you risk losing data. Overview - http://satlug.jvpappas.net/ Extend (grow) - http://www.tldp.org/HOWTO/LVM-HOWTO/extendlv.html Reduce (shrink) - http://www.tldp.org/HOWTO/LVM-HOWTO/reducelv.html | ||||
| File System | Grow | Shrink | Tool(s) | Comments |
|---|---|---|---|---|
| ext2,3 | Yes | Yes | ||
| ReiserFS, Reiser4 | Yes | Yes | ||
| XFS | Yes | No | You can NOT make a XFS partition smaller online. The only way to shrink is to do a complete dump, mkfs and restore. An XFS filesystem may be enlarged by using xfs_growfs(8). If using partitions, you need to have free space after this partition to do so. Remove partition, recreate it larger with the exact same starting point. Run xfs_growfs to make the partition larger. Note - editing partition tables is a dangerous pastime, so back up your filesystem before doing so. Using XFS filesystems on top of a volume manager makes this a lot easier.

the focus is on aggressively caching and aggregating file system operations to improve performance by economizing on the number
of actual disk accesses required for each file system operation. Newer networking technologies allow multiple machines (nodes)
to share storage devices. IBMs General Parallel File System (GPFS) or Red Hats Global File System are representing distributed
file system technologies that are taking a shared, network-attached storage approach. These file systems are built on the premise
that a shared disk file system has to exist within the context of a cluster infrastructure, and has to provide proper error handling
and recovery, as well as the best performance possible (performance, availability, and scalability features are key requirements).
The goal of this presentation is to elaborate on the terminology's surrounding the file systems that are being used in a Linux
cluster based environment. Some of the terms actually overlap, which may result in misconceptions and confusion on the user site,
an issue that is addressed in this talk. Further, this presentation discusses the classification of some the applications that may
be executed on a Linux cluster. To illustrate cluster file system technology, IBMs GPFS and Red Hats GFS file system are introduced
in more detail. The last part of the presentation briefly focuses on Sun Microsystems ZFS file system. While ZFS today is considered
a local file system solution, some of the features embedded in the design have the potential to revolutionize the file system industry.

There's also a link to <http://blogs.sun.com/relling/entry/zfs_raid_recommendations_space_performance1> which has the "all-in" version of the charts.
Then, for the specific application of NFS on ZFS, I found the page at <http://developers.sun.com/solaris/articles/nfs_zfs.html> which talks about using NFS on ZFS.
And the ZFS Best Practices wiki at <http://www.solarisinternals.com/wiki/index.php/ZFS_Best_Practices_Guide> links to an interesting page at <http://blogs.sun.com/roch/category/ZFS> which has all sorts of other interesting stuff, which I believe includes a way of calculating how you should size your zpools and your RAID-Z groups to achieve a given IOPs rate.
The "ZFS and Database Recommendations" page in the ZFS Best Practices wiki also has some recent tips regarding the use of ztune for setting prefetches and concurrent I/O values. There's also a ZFS Storage Pools Recommendations section, which might be interesting. I also noted a mention of Sun StorageTek Availability Suite (AVS), which might or might not be useful in terms of volume replication, point-in-time snapshots, or even continuous data replication.

I've actually done a survey of ZFS articles recently and I found a number that were very interesting:
For a detailed comparison of various different configurations specific to the Thumper, see
<http://blogs.sun.com/relling/entry/zfs_raid_recommendations_space_performance>.
I particularly like his calculations comparing the IOPs performance of a 73GB 2.5" Seagate Saviio SAS drive against a 750GB 3.5" Seagate Barracude SATA drive.
There's also a link to <http://blogs.sun.com/relling/entry/zfs_raid_recommendations_space_performance1> which has the "all-in" version of the charts.
Then, for the specific application of NFS on ZFS, I found the page at <http://developers.sun.com/solaris/articles/nfs_zfs.html> which talks about using NFS on ZFS.
And the ZFS Best Practices wiki at <http://www.solarisinternals.com/wiki/index.php/ZFS_Best_Practices_Guide> links to an interesting page at <http://blogs.sun.com/roch/category/ZFS> which has all sorts of other interesting stuff, which I believe includes a way of calculating how you should size your zpools and your RAID-Z groups to achieve a given IOPs rate.
The "ZFS and Database Recommendations" page in the ZFS Best Practices wiki also has some recent tips regarding the use of ztune for setting prefetches and concurrent I/O values. There's also a ZFS Storage Pools Recommendations section, which might be interesting. I also noted a mention of Sun StorageTek Availability Suite (AVS), which might or might not be useful in terms of volume replication, point-in-time snapshots, or even continuous data replication. Or, if you want to avoid AVS, you might be able to play around with ZFS send & receive, as Mark Round does at <http://www.markround.com/archives/38-ZFS-Replication.html#extended>.
Eric Kustarz has some interesting ZFS benchmarking & tuning tips on his page at <http://blogs.sun.com/erickustarz/category/ZFS>, including links to DTrace tools to help you look deeply into the ZFS code and see where it's spending all its time, and how you can look at and tune vq_max_pending, etc....

Special Presentation. For the January meeting we will have a presentation by Dr. Dominique Heger from Fortuitous Technologies
in Austin on filesystems that can be used in clusters.
The following is his abstract of the talk:
Traditional, local file systems support a persistent name space. A local file system views devices as being locally attached,
the devices are not shared, and hence there is no need in the file system design to enforce device- sharing semantics. Instead,
the focus is on aggressively caching and aggregating file system operations to improve performance by economizing on the number
of actual disk accesses required for each file system operation. Newer networking technologies allow multiple machines (nodes)
to share storage devices. IBMs General Parallel File System (GPFS) or Red Hats Global File System are representing distributed
file system technologies that are taking a shared, network-attached storage approach. These file systems are built on the premise
that a shared disk file system has to exist within the context of a cluster infrastructure, and has to provide proper error handling
and recovery, as well as the best performance possible (performance, availability, and scalability features are key requirements).
The goal of this presentation is to elaborate on the terminology's surrounding the file systems that are being used in a Linux
cluster based environment. Some of the terms actually overlap, which may result in misconceptions and confusion on the user site,
an issue that is addressed in this talk. Further, this presentation discusses the classification of some the applications that may
be executed on a Linux cluster. To illustrate cluster file system technology, IBMs GPFS and Red Hats GFS file system are introduced
in more detail. The last part of the presentation briefly focuses on Sun Microsystems ZFS file system. While ZFS today is considered
a local file system solution, some of the features embedded in the design have the potential to revolutionize the file system industry.

| Logical volumes can be reduced in size as well as increased. However, it is very important to remember to reduce the size of the file system or whatever is residing in the volume before shrinking the volume itself, otherwise you risk losing data.

|---|---|---|---|---|
| ext2,3 | Yes | Yes | ||
| ReiserFS, Reiser4 | Yes | Yes | ||
| XFS | Yes | No | You can NOT make a XFS partition smaller online. The only way to shrink is to do a complete dump, mkfs and restore. An XFS filesystem may be enlarged by using xfs_growfs(8). If using partitions, you need to have free space after this partition to do so. Remove partition, recreate it larger with the exact same starting point. Run xfs_growfs to make the partition larger. Note - editing partition tables is a dangerous pastime, so back up your filesystem before doing so. Using XFS filesystems on top of a volume manager makes this a lot easier.

And the ZFS Best Practices wiki at <http://www.solarisinternals.com/wiki/index.php/ZFS_Best_Practices_Guide> links to an interesting page at <http://blogs.sun.com/roch/category/ZFS> which has all sorts of other interesting stuff, which I believe includes a way of calculating how you should size your zpools and your RAID-Z groups to achieve a given IOPs? rate.
The "ZFS and Database Recommendations" page in the ZFS Best Practices wiki also has some recent tips regarding the use of ztune for setting prefetches and concurrent I/O values. There's also a ZFS Storage Pools Recommendations section, which might be interesting. I also noted a mention of Sun StorageTek? Availability Suite (AVS), which might or might not be useful in terms of volume replication, point-in-time snapshots, or even continuous data replication. Or, if you want to avoid AVS, you might be able to play around with ZFS send & receive, as Mark Round does at <http://www.markround.com/archives/38-ZFS-Replication.html#extended>.
Eric Kustarz has some interesting ZFS benchmarking & tuning tips on his page at <http://blogs.sun.com/erickustarz/category/ZFS>, including links to DTrace? tools to help you look deeply into the ZFS code and see where it's spending all its time, and how you can look at and tune vq_max_pending, etc....
I also found an interesting page on Lustre, ZFS, and Linux at <http://liquidat.wordpress.com/2007/07/17/lustre-runs-zfs-on-linux/>.

| XFS | Yes | No | You can NOT make a XFS partition smaller online. The only way to shrink is to do a complete dump, mkfs and restore. An XFS filesystem may be enlarged by using xfs_growfs(8). If using partitions, you need to have free space after this partition to do so. Remove partition, recreate it larger with the exact same starting point. Run xfs_growfs to make the partition larger. Note - editing partition tables is a dangerous pastime, so back up your filesystem before doing so. Using XFS filesystems on top of a volume manager makes this a lot easier. |

| Logical volumes can be reduced in size as well as increased. However, it is very important to remember to reduce the size of the file system or whatever is residing in the volume before shrinking the volume itself, otherwise you risk losing data.

Special Presentation. For the January meeting we will have a presentation by Dr. Dominique Heger from Fortuitous Technologies
in Austin on filesystems that can be used in clusters.
The following is his abstract of the talk:
Traditional, local file systems support a persistent name space. A local file system views devices as being locally attached,
the devices are not shared, and hence there is no need in the file system design to enforce device- sharing semantics. Instead,
the focus is on aggressively caching and aggregating file system operations to improve performance by economizing on the number
of actual disk accesses required for each file system operation. Newer networking technologies allow multiple machines (nodes)
to share storage devices. IBMs General Parallel File System (GPFS) or Red Hats Global File System are representing distributed
file system technologies that are taking a shared, network-attached storage approach. These file systems are built on the premise
that a shared disk file system has to exist within the context of a cluster infrastructure, and has to provide proper error handling
and recovery, as well as the best performance possible (performance, availability, and scalability features are key requirements).
The goal of this presentation is to elaborate on the terminology's surrounding the file systems that are being used in a Linux
cluster based environment. Some of the terms actually overlap, which may result in misconceptions and confusion on the user site,
an issue that is addressed in this talk. Further, this presentation discusses the classification of some the applications that may
be executed on a Linux cluster. To illustrate cluster file system technology, IBMs GPFS and Red Hats GFS file system are introduced
in more detail. The last part of the presentation briefly focuses on Sun Microsystems ZFS file system. While ZFS today is considered
a local file system solution, some of the features embedded in the design have the potential to revolutionize the file system industry.
