Good morning,

Any advice on how to remove those stale device mapper entries?

Thank you,

Sahina,

I believe you're correct regarding the stale devicemapper entries.

Before this started happening, I added a new iscsi storage domain. Host 1 couldn't communicate with it and the engine kept setting host 1 as non-operational. I removed the iscsi domain to get host 1 working again but the other two host must still think the iscsi storage is attached.

Below is the ouput from both hosts.

I almost forgot about python-blivet. All 3 hosts are on version 0.61.15.59-1.

The hosts and engine were updated using the snapshot repo last week. I updated them just now. I just noticed that host 2 and required the same 20 updates but host 1 required an additional update, ovirt-engine-appliance.

Hello Sahina,

Thanks for the response.

Attached are the requested supervsdm logs from both hosts.

Seems to be an error returned by lvm module.

" lvm lvs -a --unit k --nosuffix --nameprefixes --unquoted --noheadings -ovg_name,lv_name,lv_uuid,lv_size,lv_attr,segtype" - seems to throw this error. Can you check?

Do you have stale devicemapper entries on these hosts?

Could you provide the supervdsm.log from either host2 or host3.

Were the packages on these hosts updated?
What's the version of python-blivet? Is this different from host1?

Good morning oVirt community,
I need some assistance.
I am running a 3 host, hosted engine, gluster environment. The hosts are running centos 7.3 and the engine is version 4.1.2.3
Since yesterday, every 2 hours, the engine reports the error below on host 2 and 3.
event ID 10802
VDSM <host> command GetStorageDeviceListVDS failed: 'gluster_vg_sdb-/dev/mapper/36589cfc000000f05aea0f2b50f8d76e5: read failed after 0 of 4096 at 0: Input/output error'
I've attached logs from both hosts. Hosts 3 is the SPM and holds the arbiter brick of all 4 gluster volumes.
As always, your help is appreciated.
Joel
