Hi Jaroslaw, it's more important to find the root cause of the data loss , as this is definately not supposed to happen (I got myself several power outages without issues). Do you keep the logs ? For now , check if your gluster settings (gluster volume info VOL) matches the settings in the virt group (/var/lib/glusterd/group/virt - or somethinhg like that).

Gluster heal did not help and I could not start the VMs any more. Is there a way to make such setup bulletproof? Does it matter which volume type I choose - raw or qcow2? Or thin provision versus reallocated? Any other advise? _______________________________________________ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-leave@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/MRM6H2YENBP3AH...
