[lxc-users] How to set default volume size using the "volume.size" property on the pool

[Kees Bakker]

This is a follow up of https://github.com/lxc/lxd/issues/5069
(( Sorry for creating the issue, Stéphane. I thought that "issues"
were not just for bugs. ))

You said: "lxc profile set default root size 50GB should do the trick"

Alas, ...

root at maas:~# lxc profile set default root size 50GB
Description:
  Set profile configuration keys

Usage:
  lxc profile set [<remote>:]<profile> <key> <value> [flags]

Global Flags:
      --debug         Show all debug messages
      --force-local   Force using the local unix socket
  -h, --help          Print help
  -v, --verbose       Show all information messages
      --version       Print version number
Error: Invalid number of arguments

Furthermore.
Somewhere else I read your suggestion to set volume.size but
I was not able to get anything useful result. I did set the
volume,size of my storage pool, but new containers were still
created with the 10GB default.

And, perhaps related, if I have a container with a bigger volume than 10GB,
then it fails to copy that container. (Copying that container to another LXD
server with BTRFS, succeeds without problem.)

Notice that I'm using LVM storage, on Ubuntu 18.04 with LXD/LXC 3.0.1
