XOCE misidentifing Orphaned Snapshots with XCP-ng 8.1
-
Hi @Anonabhar
Thank you for your report.
The XO logic is based on the
snapshot_ofproperty which indicates if a snapshot is attached to a VM or not.After looking at your issue, it means that this property isn't correctly updated on migrating a VM with snapshots to a freshly installed XCP 8.1.
I'm not able to reproduce it on migrating a VM with a snapshot from an old XCP 8.1 to a freshly installed XCP 8.1.

Hi @badrAZ ,
Thanks for the info. Is there any way I can view what properties are on the snapshot to check this? (and report back)
As a side-note, I have also just taken a snapshot of a VM that was not migrated in and it is also showing the same behavior in the "Dashboard -> Health" screen.
Kind Regards,
~Peg -
Yes, you can get the snapshot's record using the xo-cli.
The command is
xo-cli list-objects id=snapshotId
I'll need also the record of its VM. Thank you

Hi @badrAZ ,
Ok.. I think I got the information you are wanting..
This is the dump from the VM:

Thank you for your response,
The field

Hi @badrAZ
Thanks for your help. I got a really strange response (as in... Nothing...)
[09:18 shineyg8-2-1 ~]# xe vm-list uuid=c830ce0b-d03d-9cb4-53ce-fbd0bc258208 params=snapshot-of [09:19 shineyg8-2-1 ~]#But if I do it against the original (base) VM I get:

That's because you need to use
xe snapshot-param-list. -
Ah, that is better 8-) This is what I get this time...

@Anonabhar It seems that the property
snapshot-ofisn't correctly reported byXO. Did you tried to disconnect/reconnect the server containing this snapshot to see if it resolves your issue?And please give me the version of your
xo-server. -
Hi @badrAZ
Well.. Monkey Poo!!!!!
Disconnecting the server and re-enabling the server did clear the issue. I have made a few snapshots and run a few backups to cause snapshots to be rotated and all is looking good..
Something must have been stuck in the original connection?
FYI:
Please mark this as solved...
~Peg

Which isn't normal is the fact XO should "reset" the connection and fetch all objects again to avoid "partial" object info… @badrAZ we should investigate on that, we can't rely on just disconnect/reconnect in such situations.
