more examples of rampant OSD memory consumption:

The OOM-killer is on the rampage and striking down hapless OSDs when
the cluster is under heavy client IO.
The memory target does not seem to be much of a limit, is this intentional?
root@cnx-11:~# ceph-conf --show-config|fgrep osd_memory_target
osd_memory_target = 4294967296

Hi all,
I'm running a Ceph Mimic cluster 13.2.6 and we use the ceph-balancer
in upmap mode. This cluster is fairly old and pre-Mimic we used to set
osd reweights to balance the standard deviation of the cluster. Since
moving to Mimic about 9 months ago I enabled the ceph-balancer with
upmap mode

Hi,
is it possible to run MDS on a newer version than the monitoring nodes?
I mean we run monitoring nodes on 12.2.10 and would like to upgrade
the MDS to 12.2.13 is this possible?
Best,

Hello Casper,
did you found an answer on this topic?
my guess is, that with "ceph pg repair" the copy of primary osd will
overwrite the 2nd and 3rd - in case it is readable.. but what is when it
is not readable? :thinking:
Would be nice to know if there is a way to tell ceph to repair pg with

You should do a "ceph versions" on a mon and ensure all your OSDs are
nautilus and if so set "ceph osd require-osd-release nautilus" then try to
increase pg num. Upgrading to a more recent nautilus release is also
probably a
Possible without downtime: Configure multi-site, create a new zone for
the new pool, let the cluster sync to itself, do a failover to the new
zone, delete old zone.
