Description Gordon Watson 2018-03-27 14:20:28 UTC
Description of problem:

The 'Active VM' snapshot does not exist in the snapshots table in the database for a specific VM. The uuid does exist however in the 'vm_snapshot_id' fields of the active images for each disk of that VM.

A volume creation error occurred at the time when a snapshot was taken in which this uuid was generated as the Active VM snapshot id.


Version-Release number of selected component (if applicable):

RHV 4.1.8
RHEL .4 hosts;
  vdsm-4.19.45-1.el7

Verify according to https://bugzilla.redhat.com/show_bug.cgi?id=1584993#c20

Comment 9 Kevin Alon Goldblatt 2018-10-17 13:16:53 UTC
Verified with the following code:
----------------------------------------
ovirt-engine-4.3.0-0.0.master.20181012165724.gitd25f971.el7.noarch
vdsm-4.30.0-640.git6fd8327.el7.x86_64

Verified with the following scenario:
----------------------------------------
1. Create VM with disk
2. Block access to storage from host
3. Create snapshot - fails to create snapshot and the Active snapshot is still in tact
4. Unblock the access to the storage domain from the host
5. Create a new snapshot now >>>>> Works fine
