This isn't a bug against Launchpad (i.e. the launchpad.net site itself). Judging from the history of https://github.com/lxc/lxd/issues/5962, it seems as though Stéphane's view was that it's a kernel bug, so reassigning there.
** Bug watch added: LXD bug tracker #5962 https://github.com/lxc/lxd/issues/5962 ** Project changed: launchpad => linux (Ubuntu) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1836707 Title: LXD Storage pool on an NFS share strange user mapping Status in linux package in Ubuntu: New Bug description: Hi Ref: 18.04 LTS I originally posted this problem on JUJU discourse (https://discourse.jujucharms.com/t/lxc-with-nfs-storage-pool-fail- bootstrap-and-deploy/1654) but then move to LXD issue (https://github.com/lxc/lxd/issues/5962). The problem is when an LXD container has a storage pool on an NFS share is dir mode creating files either touch, vim, ... the UID of the file is set to nobody but chown of the file to root fixes the problem. I am in the process of testing 19.04 and 19.10 as well.
