[ovirt-users] Re: VMs hang periodically: gluster problem?

Hello. I did a full backup using veeam but I recorded many errors in the gluster log. This is the log (https://cloud.ssis.sm/index.php/s/KRimf5MLXK3Ds3d). The log is from the same node where veeam-proxy and the backupped VMs resides. Both are running in the gv1 storage domain. See that hours are reported in GMT and the backup started at 15:55:48 GMT and ended at 16:04:35. The log is full of errors that I cannot understand: ...
