I applied this patch and restarted vdsmd on both nodes
(maintenance->restart->activate).
The errors still occur, but it is limited to fewer machines ( see [1] ).
- Almost all VMs were imported with virt-v2v (not only the VMs with errors).
- Almost all VMs were migrated to another storage domain (offline).
- Migration to another host was done with all VMs
The current vdsm logs for both are attached to this e-mail.
Please let me know if you need any additional information.
[1]: unique sampling.py errors on both nodes.
