To increase the speed at which deleted data that is shared between deduplicated and cloned files is freed on the cluster, run the ShadowStoreDelete job. Click Data Protection > SnapshotIQ > Snapshots. To reduce disk-space usage, snapshots that reference the same directory reference each other, with older snapshots referencing newer snapshots.

... and ShadowStoreDelete will clean up the space eventually. I don't know what is it about this tcsh shell that does not like.
From the Select an action list, select Delete. SyncIQ like Celerra/VNX Replicator and NetApp SnapMirror utilizes baseline snapshots to keep the 2 copies in sync, so that incrementals can be block-level changes only and not require the use of treewalks, or full file copies when only a few blocks of a file have changed. i.e.
If data contained in a snapshot is modified, the snapshot stores a physical copy of the original data, and references the copy. OneFS frees disk space that is occupied by deleted snapshots when the SnapshotDelete job is run.
good luck stopping that loop if you notice an error.
A snapshot contains a directory on a cluster, and includes all data stored in the given directory and any subdirectories that the directory contains.
I then went through and listed all available snapshots and then deleted them: show system snapshot all-members | match "Snapshot snap" request system snapshot delete
The space consumed by these deleted snapshots will not be freed until the snapshot delete job is run again. I will try this on a test system first, but it looks like its a keeper. The following information and controls appear on drwxrwxrwx 3 root wheel 14 Jan 27 06:49 data-backup-2014-01-29-_00-15 I want to be able to delete multiple snapshots greping on this a little at a time.

At this point I put a JTAC case in and was told to do a clean re-installation via tftp. Gentlemen, please be very careful if you script something like this on a cluster that utilizes SyncIQ for Data Protection. Thanks for the heads up. The space consumed by the deleted snapshots is not freed until the snapshot delete job is run again. How might I do that using the isi snapshot snapshots delete command? You don't want to ever delete these, if you do, you could require a full data copy, or at the minimum a tree-walk to get back into sync. Also, if you delete a snapshot that contains clones or cloned files, data in a shadow store might no longer be referenced by files on the cluster; OneFS deletes unreferenced data in a shadow store when the ShadowStoreDelete job is run. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. We have 5 snapshots in SnapShotIQ We do not have the option to delete the snapshots - there is no Total Number of Snapshot Aliases If a snapshot references data stored by another snapshot, the data is not freed until both snapshots are deleted. isilon1-6$ ls -l | grep data-backup-2014-01. In this post I’m going to review the most useful commands for managing SyncIQ replication jobs and SnapshotIQ snapshots on the Isilon.
Optional: To increase the speed at which deleted snapshot data is freed on the cluster, run the SnapshotDelete job. I am horrible at command line scripting. OneFS routinely runs both the ShadowStoreDelete and SnapshotDelete jobs. isilon1-6$ ls -l | grep data-backup-2014-01, drwxrwxrwx 3 root wheel 14 Jan 27 06:49 data-backup-2014-01-29-_00-15, drwxrwxrwx 3 root wheel 14 Jan 27 06:49 data-backup-2014-01-30-_00-15, drwxrwxrwx 3 root wheel 14 Jan 27 06:49 data-backup-2014-01-31-_00-15.
yep, i am getting the same thing.

Here are two from my lab cluster.
The space consumed by the deleted snapshots is not freed until the snapshot delete job is run again.
Total Number of Snapshots Pending Deletion Displays the total number of snapshots that were deleted since the last snapshot delete job was run. A OneFS snapshot is a logical pointer to data stored on a cluster at a specific point in time.
8781 SIQ-Failover-rep-azone1-2014-07-18_11-44-45 /ifs/isi02/azone1, 8793 SIQ-92d58afc9c96d5bfc82c92e8cb12e1d1-latest /ifs, for i in `isi snapshot snapshots list | grep /ifs | grep -v "SIQ-" | awk '{print $2}'`; echo isi snapshot snapshots delete --snapshot=$i --force; isi snapshot snapshots delete --snapshot=$i --force;done. I am trying to clean up snapshots and when I list and grep on a certain snapshot schedule that I am trying to clean up I wanted to be able to delete multiple snapshots with one command. not sure what you are doing with your script but if you just want to list of the first 161 snapshots, you can run this command: I am trying to clean up snapshots and when I list and grep on a certain snapshot schedule that I am trying to clean up I wanted to be able to delete multiple snapshots with one command. These snapshots are listed in the 'isi snap snaps list' output that you posted above, but have very distinctive names.
Total Number of Snapshots Pending Deletion Indicates the total number of snapshots that were deleted on the cluster since the last snapshot delete job was run.
If i had 175 snapshots and I was performing a snapshot clean up and wanted to delete all but the latest 14 snapshots how would I formulate that within the snapshot delete command? Therefore, deleting a snapshot might not free the entire amount of space displayed because another snapshot might be referencing the data stored by the snapshot.
In the list of snapshots, select the snapshot or snapshots that you want to delete. You can delete a snapshot if you no longer want to access the data that is contained in the snapshot.
Again, I will try on a Isilon VM before performing it on the production cluster. Drop to bash and repeat your comands and it will work (type bash and hit enter).
