Hello everyone,
I'm about to start digging through the mailing list archives in search of a
solution but thought I would post to the list as well. I'm running oVirt
3.6 on a 2 node CentOS7 cluster backed by fiber channel storage and with a
separate engine VM running outside of the cluster (NOT hosted-engine).
When I try to move the SPM role from one node to the other I get the
following in the web interface:
[image: Inline image 1]
When I look into /var/log/ovirt-engine/engine.log I see the following:
2017-01-18 13:35:09,332 ERROR
[org.ovirt.engine.core.vdsbroker.vdsbroker.HSMGetAllTasksStatusesVDSCommand]
(default task-26) [6990cfca] Failed in 'HSMGetAllTasksStatusesVDS' method

(default task-26) [6990cfca] Correlation ID: null, Call Stack: null, Custom
Event ID: -1, Message: VDSM v6 command failed: Logical Volume extend failed
When I look at the task list on the host currently holding the SPM role (in
this case 'v6'), using: vdsClient -s 0 getAllTasks, I see a long list like
this:
dc75d3e7-cea7-449b-9a04-76fd8ef0f82b :
verb = downloadImageFromStream
code = 554
state = recovered
tag = spm
result =
message = Logical Volume extend failed
id = dc75d3e7-cea7-449b-9a04-76fd8ef0f82b
When I look at /var/log/vdsm/vdsm.log on the host in question (v6) I see
messages like this:
'531dd533-22b1-47a0-aae8-76c1dd7d9a56': {'code': 554, 'tag':
u'spm',
'state': 'recovered', 'verb': 'downloadImageFromStreaam',
'result': '',
'message': 'Logical Volume extend failed', 'id':
'531dd533-22b1-47a0-aae8-76c1dd7d9a56'}
As well as the error from the attempted extend of the logical volume:

The logical volume in question is an OVF_STORE disk that lives on one of
the fiber channel backed LUNs. If I run:
vdsClient -s 0 ClearTask TASK-UUID-HERE
for each task that appears in the:
vdsClient -s 0 getAllTasks
output then they disappear and I'm able to move the SPM role to the other
host.
This problem then crops up again on the new host once the SPM role is
moved. What's going on here? Does anyone have any insight as to how to
prevent this task from re-appearing? Or why it's failing in the first
place?
