This bug was fixed in the package zfs-linux - 0.6.5.6-0ubuntu24 --------------- zfs-linux (0.6.5.6-0ubuntu24) xenial; urgency=medium
* Allow multiple mounts of zfs datasets (LP: #1759848) - Change zpl_mount() to call sget() directly with it's own test callback. Passing the objset_t object as the fs data allows checking if a superblock already exists for the dataset, and in that case we just need to return a new reference for the sb's root dentry. -- Colin Ian King <colin.k...@canonical.com> Thu, 25 Jun 2018 14:31:14 +0100 ** Changed in: zfs-linux (Ubuntu Xenial) Status: Fix Committed => Fix Released -- 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/1759848 Title: Allow multiple mounts of zfs datasets Status in linux package in Ubuntu: Fix Released Status in zfs-linux package in Ubuntu: Fix Released Status in linux source package in Xenial: Fix Committed Status in zfs-linux source package in Xenial: Fix Released Status in linux source package in Bionic: Fix Released Status in zfs-linux source package in Bionic: Fix Released Bug description: === SRU Justification, Xenial == An attempt to mount an already mounted zfs dataset should return a new mount referencing the existing super block, but instead it returns an error. Operations such as bind mounts and unsharing mount namespaces create new mounts for the sb, which can cause operations to fail which involve unmounting and remounting the dataset. == Fix == Backport of upstream fix https://trello.com/c/l89Ygj28/352-allow- multiple-mounts-of-zfs-datasets to allow multiple mounts This fix from Seth addresses this issue == Regression potential == Like all backports, this has a potential to be incorrectly backported and break the ZFS mounting. However, any breakage should be picked up via the ZFS smoke tests that thoroughly exercise mounting/dismounting options. At worst, the mounting won't work, but this has been tested, so I doubt this is a possibility.
