[ovirt-users] Re: iSCSI multipath with separate subnets... still not possible in 4.4.x?
I second that, I’ve tirelessly talked about this and just given up, it’s a basic feature that keeps oVirt lagging behind. > On 18 Jul 2020, at 04:47, Uwe Laverenz wrote: > > Hi Mark, > > Am 14.07.20 um 02:14 schrieb Mark R: > >> I'm looking through quite a few bug reports and mailing list threads, >> but want to make sure I'm not missing some recent development.

[ovirt-users] Re: VDSM HOST ISSUE - Message timeout which can be caused by communication issues
Hm... then you need to play on a TEST ovirt with the options described in in https://www.ovirt.org/develop/developer-guide/engine/engine-config-options.html Some of the more interesting options are: SSHInactivityTimoutSeconds TimeoutToResetVdsInSeconds VDSAttemptsToResetCount VdsRecoveryTimeoutInMintues VdsRefreshRate vdsTimeout Try them first in a test system before deploying on production.
