Pesky volume snapshot schedule
Hello,
I was hoping someone could help me investigate and fix the issue that I am having with one of the volume snapshots schedules. I am running ACS version 4.6.2 on Ubuntu 14.04 with latest updates, etc.
I've got a 200 gig vm root disk image which I am snapshotting on a daily basis. I've created the schedule to take a snapshot at 9:30pm every day and keeping 8 snapshots. The schedule is executing and the image is being snapshotted and placed on the nfs secondary storage. However, ACS does not remove the old snapshots at all and I am ending up with dozens and dozens of snapshots of this particular volume. I have to manually remove them to keep the secondary storage from filling up. The problem is with this particular volume. I've got several other daily snapshots schedules which are working perfectly well and their clean up works well as well.
I've compared db values for this particular volume with other volumes and I can't find any difference apart from the disk size. The db values for the schedule are also correct and look similar to a properly working schedule (apart from the start time). I've also tried to remove the schedule and create a new one at no avail.
Could someone help me fix the issue?
Many thanks
Andrei

If its not available then set “job.cancel.threshold.minutes" to value greater than “backup.snapshot.wait”. Make sure you are setting them up properly as per your environment. This will effect all the jobs.

Hi Anshul,
Had a look in ACS GUI and I can't find the 'volume.snapshot.job.cancel.threshold' option. Has it been introduced in ACS 4.7 or 4.8 versions? I am running 4.6.2 at the moment.
Thanks

Try setting "volume.snapshot.job.cancel.threshold" value greater than
"backup.snapshot.wait" value. This will make sure that backup snapshot is
cancelled before job cancellation. This in turn will take care of cleanup of
old snapshots.
