Re: Stuck PGs blocked_by non-existent OSDs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Stuck unclean and stuck inactive. I can fire up a full query and
health dump somewhere useful if you want (full pg query info on ones
listed in health detail, tree, osd dump etc). There were blocked_by
operations that no longer exist after doing the OSD addition.

Side note, spent some time yesterday writing some bash to do this
programatically (might be useful to others, will throw on github)
