Public bug reported: Currently package zfsutils-linux contains systemd target file /lib/systemd/system/zfs.target that specifies following dependencies: Requires=zfs-mount.service Requires=zfs-share.service Wants=zed.service
zfs-share.service is not essential in setups where file sharing is not used, or when it is configured without the use of the zfs utility. The user may therefore choose to mask this service. However, doing so has an unexpected and confusing effect, preventing zfs from starting on boot at all. This is because zfs.target is the only zfs-related unit that is wanted by multi-user.target, and if one of its required services is masked, zfs.target is skipped, together with zfs-mount.service. A solution is to replace "Requires=zfs-share.service" with "Wants=zfs- share.service". Steps to reproduce: systemctl mask zfs-share.service reboot Expected results: Module zfs is loaded zfs-mount.service is active and ZFS filesystems are mounted ZFS filesystems are not shared Observed results: Module zfs is not loaded ZFS filesystems are not mounted zpool status produces an error: "The ZFS modules are not loaded. Try running '/sbin/modprobe zfs' as root to load them." $ lsb_release -rd Description: Ubuntu 16.04.1 LTS Release: 16.04 $ apt-cache policy zfsutils-linux zfsutils-linux: Installed: 0.6.5.6-0ubuntu10 ** Affects: zfs-linux (Ubuntu) Importance: Undecided Status: New ** Package changed: autofs (Ubuntu) => zfs-linux (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1614789 Title: zfs.target should not require zfs-share.service To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/zfs-linux/+bug/1614789/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
