Description Spindel Ljungmark 2018-04-24 22:03:58 UTC 
The default configuration for btrfsmainenance is to do scrub and balance on / .  With transactional server profile, / is read-only and /var is read-write, thus maintenance fails and never runs.

I'd suggest either changing the default to `auto` or making a read-write path the default ( /var).

/var is a bad choice, depending on your installation this could also be read-only.

We use /.snapshots as fallback, if / is read-only everywhere else.

issue is still present and it makes MicroOS and its derivative not running scrub operation by default, which is wrong (even if / is read-only).

Since scrub can be run in RO mode (/etc/sysconfig/btrfsmaintenance can be configured this way) , it would be better to btrfs-scrub.sh to detect this automatically and run in RO mode if partition is mounted RO.
