Public bug reported: I've got a ZFS volume on an ISCSI target, once the system boots I can bring it online.
My ISCSI target shows up as: root@test:/home/rob# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 8.1T 0 disk root@test:/home/rob# zpool status pool: data2 state: ONLINE scan: none requested config: NAME STATE READ WRITE CKSUM data2 ONLINE 0 0 0 sda ONLINE 0 0 0 errors: No known data errors root@test:/home/rob# df -h Filesystem Size Used Avail Use% Mounted on ------------------- snip -------------------------- data2 3.1T 0 3.1T 0% /data2 data2/backup 3.2T 165G 3.1T 6% /data2/backup data2/test 7.7T 4.7T 3.1T 61% /data2/test However in the case of a system shutdown/reboot the system tries to unmount the disk after the network has been brought down which obviously fails. When booting the system the zpool never gets imported as the 'zfs- import-cache.service' runs before the iscsi target is initiated. ** Affects: systemd (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1594634 Title: ZFS on iscsi target fails at boot/shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1594634/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
