ZFS legacy mount fails
I'm trying to mount ZFS dataset with /etc/fstab file. Added string in it:
doublediskpool/systemlog /mnt zfs relatime,defaults 0 2
Rebooted, and system fails to boot. In boot log I see that spl and zfs
modules loaded, than:
systemd: mnt.mount: Mount process exited, code=exited status=1
systemd: Failes to mount /mnt.
After this zfs.target successfully starts, and system fall into
Tryed to add in [Install] section of /lib/systemd/system/zfs.target such
but it does not help.
If I enter command (that systemd fail to execute) in emergency mode or
# mount doublediskpool/systemlog /mnt -t zfs -o relatime,defaults
than mount executed successfully.
Nothing changes if I set another mountpoint.
How this can be fixed?
