Proxmox tries to import ZFS Pool belonging to TrueNAS VM?

[JackSpidy]

So I've got Proxmox running with a TrueNAS VM, I've followed the Proxmox Wiki page for passing disks through, and then set those disks up in TrueNAS, and works great, but when the node is rebooted, Proxmox seems to try and fail to grab the ZFS pool that TrueNAS has created, and on the TrueNAS VMs first autostart it doesn't seem to launch correctly, on a second bootup of the VM however, it seems fine, the VM picks up the drives and the pool is available over network with no problems.

Is there any way to stop Proxmox from seeing and trying to grab these drives? It's not like the node gets shut off too often, but I do occasionally turn it off when I'm out for weekends or know I won't be accessing any of it's services, and it just concerns me a bit with the drives getting dragged around like that and all. Thanks in advance!

I am in the same situation after a power failure. The difference is, that my Proxmox doesn't start anymore (it starts, but I have no zfs or VMs)

could you be more specific what proxmox seems to do here?

what's the name of the truenas pool?

any output from the logs/console with the appropriate error?

afaik, proxmox does not automatically import zfs pools on boot which are in use by different system. zfs also has some mechanism inside to avoid this

check if zfs-import-scan service is disabled


# systemctl list-unit-files --all|grep scan
lvm2-pvscan@.service static -
zfs-import-scan.service disabled disabled

I have disabled the service
root@proxmox:~# systemctl list-unit-files --all|grep scan
zfs-import-scan.service disabled disabled

but still systamctl say its enabled:

root@proxmox:~# systemctl status zfs-import-cache
× zfs-import-cache.service - Import ZFS pools by cache file

zfs-import-cache and zfs-import-scan are two different services...
