Public bug reported:
$ apt list lxc lxd
Listing... Done
lxc/xenial-updates,xenial-updates,now 2.0.5-0ubuntu1~ubuntu16.04.2 all
[installed]
lxd/xenial-updates,now 2.0.5-0ubuntu1~ubuntu16.04.1 amd64 [installed]
I was changing the memory limits of a container and mistyped a suffix:
lxc config set docker limits.memory 512M
and now that setting is in lxd.db and prevents me from doing anything to
that container:
$lxc list
+--------+-------+------+------+------------+-----------+
| NAME | STATE | IPV4 | IPV6 | TYPE | SNAPSHOTS |
+--------+-------+------+------+------------+-----------+
| docker | ERROR | | | PERSISTENT | 0 |
+--------+-------+------+------+------------+-----------+
$lxc start docker
error: Unsupported suffix: 2M
$lxc config set docker limits.memory 512MB
error: Unsupported suffix: 2M
$lxc stop docker
error: Unsupported suffix: 2M
Try `lxc info --show-log docker` for more info
$lxc info --show-log docker
error: Unsupported suffix: 2M
$ lxc delete docker
error: Unsupported suffix: 2M
I could possibly use a (purely guessing) sqlite client to fix
/var/lib/lxd.db entry that has the memory setting that is bad.
/var/lib/lxd$ grep 512M lxd.db
Binary file lxd.db matches
/var/lib/lxd$ grep 512MB lxd.db
This appears to be a data sanity check (bad data got into container
setting) that lxd doesn't like but then won't allow one to override /
remove / fix
I haven't checked backports for the newer 2.5 releases of lxd/lxc but it
could be a problem in that code branch as well.
Just thought somebody would want to know that this simple-to-make typo
(M instead of MB) has completely made the container unusable.
