XenServer 7 - unable to delete specific snapshots

DustinB3403

I haven't tried to delete the snap created by XO (if I have to I will, of course that will break the backup chain) and require a new full.

The VM pictured is 150GB in total size.

Is this the only VM affected? How is it that you have 26TB allocated on 14TB of storage?

This host is running 3 VM's one is our file server. The file server isn't effected by this issue (also I haven't done anything with it for some time).

With this VM and another I was working to setup CR using XO to my second host.

The storage allocation is because of the nightly Delta that creates and leaves a snap on the host.

How much free space on the SR?
Has that vdi been used to clone for another vm?
If XS wont erase snapshots it is usually one of those two reasons.

DustinB3403

There is an almost 5TB free (even with 22tb allocated). The VM has been used to clone to my second host which is planned for the Continuous Replication job.

Danp

Is this XS 6.5 or XS 7?

@Danp XS7

Danp

Have you tried rescanning the SR to see if it will reclaim some of the used space?

DustinB3403

I have, the scan completes without issue.

The snap is still there.

Danp

@DustinB3403 I wouldn't expect it to magically disappear. However, the scan could result in some diskspace being freed up.

Danp

Have you looked at /var/log/SMlog on your XS to try to identify the underlying issue?

@DustinB3403
When did you clone this? December 9 @ 1244?

DustinB3403

@momurda Yea.

Which should take an exact copy of it, put it on my remote and then dump the snap once its done.

momurda

Did you do a fast copy or a full clone? If you did a fast copy that is the problem and you will have to do things.
Like export the clone then import it again to erase the snapshot chains is probably the easiest and least risky.

I used the copy function within XO to replicate it to my second host.

So delete and reimport the VM.
