Yes, but that's still not how a TrueNAS (and most other low- to
mid-range SANs) works, so is not relevant. The TrueNAS on

-seamless.
-no service interruption.
-not locked to any storage solution.
multipath was designed exactly for that.

TrueNAS HA is active/standby, so multipath has nothing to do with
rebooting/upgrading a TrueNAS.

I think its not related to something on the trueNAS side. if you are using
iscsi multipath you should be using round-robin , if one of the paths goes
down you still have the other path with your information., so no sanlock .
unfortunately if you want iscsi mpath on ovirt, its prefered to edit the

That's the way TrueNAS failover work

As soon as yous NAS goes down, qemu running the VMs will start getting EIO
errors and VMs will pause, so as to not lose any data. If the NAS upgrade
isn't a very long procedure, you might as well complete the updates, enable
the NAS, and unpause the VMs.

I'm using two TrueNAS HA SANs (FreeBSD-based ZFS) to provide storage via NFS to
7 oVirt boxes and about 25 VMs.
For SAN system upgrades I've always scheduled a maintenance window, shut down
all the oVirt stuff, upgraded the SANs, and spun everything back up. It's
pretty disruptive, but I assume
