Hi, (un)fortunately I can't test it because I managed to repair the pg.
snaptrim and snaptrim_wait have been a part of this particular pg's status. As I was trying to look deeper into the case I had a watch on ceph health detail and noticed that snaptrim/snaptrim_wait was suddenly not a part of the status anymore. So I gave it another try with ceph pg repair 18.19a and suddenly the pg's status changed to active+clean+inconsistent+repair. It repaired successfully. Is snaptrim somehow blocking repair instructions? I would have thought that repair instructions will be queued up until they can be performed but it does not seem to work as I expected it to. Anyway I'll keep your script in mind and give it a shot if it happens again.
