[Kernel-packages] [Bug 1581904] Re: File-based pools do not import on boot
I've just added "After=local-fs.target" to /lib/systemd/system/zfs- import-cache.service and now it starts almost normally. Only once I saw an error after boot saying that kernel module zfs is not loaded. So, this is not a good fix, but it shows that an issue is likely to be connected with some race condition between mounting local filesystems and zfs. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to zfs-linux in Ubuntu. https://bugs.launchpad.net/bugs/1581904 Title: File-based pools do not import on boot Status in zfs-linux package in Ubuntu: Confirmed Bug description: System: ubuntu: 16.04 zfsutils-linux: 0.6.5.6-0ubuntu8 Create sparse files and create pool: root@server:/# fallocate -l 100G /web/lxd/100gb.01 root@server:/# fallocate -l 100G /web/lxd/100gb.02 root@server:/# zpool create lxd /web/lxd/100gb.01 root@server:/# zpool add lxd /web/lxd/100gb.02 Check: root@server:/# zpool list NAME SIZE ALLOC FREE EXPANDSZ FRAGCAP DEDUP HEALTH ALTROOT lxc199G77K 199G - 0% 0% 1.00x ONLINE - After reboot: root@server:/etc/apt# zpool list no pools available Try to create another pool with that files: root@server:/# zpool create lxc /web/lxd/100gb.01 /web/lxd/100gb.02 invalid vdev specification use '-f' to override the following errors: /web/lxd/100gb.01 is part of potentially active pool 'lxd' /web/lxd/100gb.02 is part of potentially active pool 'lxd' ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: zfsutils-linux 0.6.5.6-0ubuntu8 ProcVersionSignature: Ubuntu 4.4.0-22.39-generic 4.4.8 Uname: Linux 4.4.0-22-generic x86_64 NonfreeKernelModules: zfs zunicode zcommon znvpair zavl nvidia_uvm nvidia_modeset nvidia ApportVersion: 2.20.1-0ubuntu2 Architecture: amd64 Date: Sun May 15 05:53:51 2016 InstallationDate: Installed on 2016-04-21 (23 days ago) InstallationMedia: Ubuntu 16.04 LTS "Xenial Xerus" - Release amd64 (20160420.1) ProcEnviron: LANGUAGE=en_US TERM=xterm-256color PATH=(custom, no user) LANG=en_US.UTF-8 SHELL=/bin/bash SourcePackage: zfs-linux UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/zfs-linux/+bug/1581904/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
