[solved] boot messages: failed to start zfs import

[Peter Altherr]

dear proxmox experts,

since a while i am getting two error lines when booting up my pve (please see screenshot). after boot everything runs fine. checking my 3 zfs pools in the webui shows their status as online and green. the 4tb pool does no longer exist, the 12tb pool exists but my guess is the error messages refers to a former 12tb pool which has been deleted and recreated. any clues are most welcome how to get rid of these lines.

error messages:


my current pools in pve webui:

Hi,
Proxmox VE imports the ZFS pools by cache file. From what you describe, it seems that these services are leftovers, which can be disabled by running systemctl disable --now zfs-import@ZFS_4Tb_HDD_RAIDZ.service zfs-import@ZFS_12Tb_HDD_RAIDZ.service.

Also, please double check afterwards, that the improt by cache file service is indeed enabled and active by running systemctl status zfs-import-cache.service

thanks a lot chris. before i give it a try: the command does not harm my existing 12tb pool as it has the same name?

No, the service only handles zpool imports. It does not touch anything else. You can see what it does by running cat /usr/lib/systemd/system/zfs-import@.service. Note that this is a template service, so systemd replaces %i and %I with the argument provided after the @, see https://www.freedesktop.org/software/systemd/man/systemd.service.html#Service Templates
