Hi,
we have a problem with some VMs which cannot be started anymore due to
an illegal disk status of a snapshot.
What happend (most likely)? we tried to snapshot those vms some days ago
but the storage domain didn't have enough free space left. Yesterday we
shut those vms down - and from then on they didn't start anymore.
What have I tried so far?
1. Via the web interface I tried to remove the snapshot - didn't work.
2. Searched the internet. Found (among other stuff) this:
https://bugzilla.redhat.com/show_bug.cgi?id=1649129
3. via /vdsm-tool dump-volume-chains/ I managed to list those 5
snapshots (see below).
The output for one machine was:
image: 2d707743-4a9e-40bb-b223-83e3be672dfe
- 9ae6ea73-94b4-4588-9a6b-ea7a58ef93c9
status: OK, voltype: INTERNAL, format: RAW, legality:
LEGAL, type: PREALLOCATED, capacity: 32212254720, truesize: 32212254720
- f7d2c014-e8f5-4413-bfc5-4aa1426cb1e2
status: ILLEGAL, voltype: LEAF, format: COW, legality:
ILLEGAL, type: SPARSE, capacity: 32212254720, truesize: 29073408
So my idea was to follow the said bugzilla thread and update the volume
- but I didn't manage to find input for the /job_id/ and /generation/.
So my question is: Does anyone have an idea on how to (force) remove a
given snapshot via vsdm-{tool|client}?
Thanks in advance!
Daniel
