We backported a wrong patch to 13.2.2. downgrade ceph to 13.2.1, then run
'ceph mds repaired fido_fs:1" .
Sorry for the trouble

Hi
Ideally we'd like to undo the whole accidental upgrade to 13.x and ensure that
ceph-deploy doesn't do another major release upgrade without a lot of warnings
Either way, I'm currently getting errors that 13.2.1 isn't available / shaman
is offline / etc
What's the best / recommended way o

fyi, downgrading to 13.2.1 doesn't seem to have fixed the issue either :(

I've experimented and whilst the downgrade looks to be working, you end up with
errors regarding unsupported feature "mimic" amongst others

cephfs is recoverable. Just set mds_wipe_sessions to 1. After mds recovers,
set it back to 0 and flush journal (ceph daemon mds.x flush journal)

Gents,
My cluster had a gap in the OSD sequence numbers at certain point.
Basically, because of missing osd auth del/rm" in a previous disk
replacement task for osd.17, a new osd.34 was created. It did not really
bother me until recently when I tried to replace all smaller disks to
bigger disks.
Hi
After I recreated one OSD + increased pg count of my erasure-coded (2+1) pool
(which was way too low, only 100 for 9 osds) the cluster started to eat
additional disk space.
First I thought that was caused by the moved PGs using additional space during
unfinished backfills. I pinned most of
Is there a way to force OSDs to remove old data?

Hi list,
I have a situation that I need to reinstall the O.S. of a single node in my
OSD cluster.
This node has 4 OSDs configured, each one has ~4 TB used.
The way that I'm thinking to proceed is to put OSD down (one each time),
stop the OSD, reinstall the O.S., and finally add the OSDs again.

Hi all,
Recently our cluster lost a drive and a node (3 drives) at the same
time. Our erasure coded pools are all k2m2, so if all is working
correctly no data is lost.
However, there were 4 PGs that stayed "incomplete" until I finally
took the suggestion in 'ceph health detail' to reduce
min_size should be at least k+1 for EC. There are times to use k for
emergencies like you had. I would suggest seeing it back to 3 once your
back to healthy.
As far as why you needed to reduce min_size, my guess would be that
recovery would have happened as long as k copies were up. Were the PG's
Set noout, reinstall the OS without going the OSDs (including any journal
partitions and maintaining any dmcrypt keys if you have encryption),
install ceph, make sure the ceph.conf file is correct,zip start OSDs, unset
noout once they're back up and in. All of the data the OSD needs to start
is on
Evening,
I am looking to decrease our max mds servers as we had a server failure and
need to remove a node.
When we attempt to decrease the number of mds servers from 5 to 4 (or any other
number) they never transition to standby. They just stay active.
