Hi Semih,
I do not know much about this issue with any practical experience to give
you an accurate shot. Checking the code (Apache CloudStack 4.6.2) I would
presume the following.
CloudStack handles a snapshot if can find a volume related to the given
snapshot. With that, the CS is able to discover the snapshot storage pool.
As in your case it could not find any volume (fails to find a "volume_id"
at table "snapshots" or the table "volumes" does not have the volume id
pointed by the snapshot); it tries to get the snapshot on the table
"snapshot_store_ref", checking for the snapshot id ("snapshot_id" column)
with the data store role of "primary" ("store_role" column).
This exception (StorageSystemSnapshotStrategy.canHandle, at line 461) is
thrown because:
- the volume has been deleted or the database has some inconsistency that
the CS cannot find a volume with the snapshot id;
- there is some inconsistency in the"snapshot_store_ref" table.
Hope I've helped,
Cheers Gabriel.
