Snapshot failure - Multi-schedule collision

Question

Hi, when we try to create a manual snapshot its working just fine. but scheduled snapshot is failing with below error. at 10PM schedule time we have only one other  share snapshot schedules so basically we have 2 shares snapshot schedules at same time , is this a problem ? Message: The snapshot daemon failed to create snapshot 'ScheduleName_duration_2013-05-23-_23-00' in schedule 'prod_nfs_share': error: Multi-schedule collision i look up in admin guides couldn't find any of this issue.

OK　I think you have same snapshot patterns for different snapshots schedule.

Change the Naming Pattern for Generated Snapshot as follows to each policy.

Snap1 Snap1_%Y-%m-%d-_%H-%M

Snap2 Snap2_%Y-%m-%d-_%H-%M

Snap3 Snap3_%Y-%m-%d-_%H-%M

By default "ScheduleName_duration" parts wouldn't change even if you modified the policy name.
You have to modify it by yourself.

I am using OneFSv7.0.2 for test but I can make different snapshots at same time. What is the results for following command: isi snapshot schedule list -v

Is OneFS version 7.0 or later, or 6.5?

I'm afraid have no experience of OneFS 7.0, but you probably find Snapshot logs in

/var/log/isi_snapshot_d.log in each nodes. Could you try to find anything?

thanks,

Hi go.y,

probably you right same schedule name for 2 shares at same time is the issue, i changed the naming pattern now will see how automated schedule works tonight at 11pm.

Question: u mentioned " I am using OneFSv7.0.2 for test but I can make different snapshots at same time. "

is onefsv7.0.2 is out already for GA ? i am waiting for 7.0.1.4 to this new version upgrade due to multiple issues

Go.Y · Answer

Oh, sorry it's just a typo.

Correct version I'm testing is OneFSv7.0.1.2.

I think OneFSv7.0.2 is not GA yet.

However, current RR is OneFSv7.0.1.5.

So I think you should get the OneFSv7.0.1.5 from downloads.

we are going to have large number of snapshots for both SMB & NFS so is there any crontab kind of job schedule available in isilon ? bec we don't want to login each day to findout how many snapshots are there and how much space they are occupied. we need email notification of these 2 components everyday.

dynamox · Answer

You can write perl/bash/korn scripts and use 'isi snapshot ….blah' commands to write your own reports and then email them out.

dynamox · Answer

Crontab is there ..not sure if Isilon folks support you using it.
