Turns out, I really messed up when changing the EC profile. Removing the
pool did not get rid of it's PGs on the OSDs that have crashed.
To get my OSDs back up I used ceph-objectstore-tool like this:
for PG in $(ceph-objectstore-tool --data-path $DIR --type=bluestore
--op=list-pgs |grep '^$POOL_ID'); do
ceph-objectstore-tool --data-path $DIR --type=bluestore --op=remove
--force --pgid=$PG
done
$DIR is the data path of the crashed OSD.
$POOL_ID is the ID of the pool with the messed up EC profile.
I'm now curious if there is an easier way to do this?
After getting rid of all PGs the OSD were able to start again. Hope this
helps someone.

Hi,
a lot of our OSD have crashed a few hours ago because of a failed
assertion:
/build/ceph-15.2.3/src/osd/ECUtil.h: 34: FAILED ceph_assert(stripe_width
% stripe_size == 0)
Full output here:
https://pastebin.com/D1SXzKsK
All OSDs are on bluestore and run 15.2.3.
I think I messed up when I tried to change an existing EC profile (using
--force) for an active EC pool.
I already tried to delete the pool and the EC profile and start the OSDs
but they keep crashing with the same assertion.
Is there a way to at least find out what the values are for stripe_width
and stripe_size?
Regards,
Michael
