Title:
LXD Storage pool on an NFS share strange user mapping
Status in linux package in Ubuntu:
Confirmed
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.
Matthew

UID mapping incorrect when creating a file.
When touching or creating a file with vim (or any other method) is
created with the UID on nobody (65534) but other files are all correct
the startup. The correct UID can be set by chown of the file
Steps to reproduce
Create container (lxc launch -s nfs ubuntu:18.04)
Access container ( lxc exec modest-ladybug -- sudo /bin/bash )
touch file (touch test)
list dir (ls -la)
