isi snapshot snaphosts delete

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:

isi snapshots list | head -161

I will try this on a test system first, but it looks like its a keeper.

Thank you,

Dynamox,

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.

i.e. 

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

I want to be able to delete multiple snapshots greping on this a little at a time.  How might I do that using the isi snapshot snapshots delete command?

Thank you,

Gentlemen, please be very careful if you script something like this on a cluster that utilizes SyncIQ for Data Protection.  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.  These snapshots are listed in the 'isi snap snaps list' output that you posted above, but have very distinctive names.

Here are two from my lab cluster.  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.

8781 SIQ-Failover-rep-azone1-2014-07-18_11-44-45 /ifs/isi02/azone1

good luck stopping that loop if you notice an error.

Thks for the precaution addition to the script.

Klosterman,

I agree.  That is why I am glad that dynamox provided a way for me to be able to see an output before I run the command.

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

Thanks for the heads up.  Again, I will try on a Isilon VM before performing it on the production cluster.

NDMP creates snaps, too...  naming schemes can change over releases...

Better choose a naming style for YOUR snapshots and positively filter for your scheme.

ctrl + c generates an interrupt. But of course you are right. My oneliner is more dangerous - but easier to use in an automated process with no user interaction.

Additionally Peter has a good point by saying you should do positive-filters on your snaps.

Dynamox,

I am need to grep on the naming convention of the snapshot gather then the path location.  I need to be sure I am grabbing specific items from certain time frames.  I dont want to delete everything from a specific path.  For some reason I keep getting this output:

What am I doing wrong?  again I need to delete only a snapshots from a certain time frame not all of the existing snapshots from a path location.

Thank you,

Ok this is completely complicated to explain, but I will try... I am working on a boot camp MAC with a Windows OS.  The tick key is not correct... Needless to say I will have to see if I can figure out how to get the tick key back.  I will let you know how it goes once I get the tick key back.

Thank you
