Hello Ceph experts,
In the last day or so, we had a few nodes randomly reboot and now unfound
objects are reported in Ceph health during cluster during recovery.
It appears that the object in question is a hit set object, which I now cannot

We are relying on the pg autoscaler to set the PGs, and so far it
seems to do the right

It should be possible to use an EC pool for CephFS data:
Right, but should I be proactively returning any reweighted OSD's that
are not 1. to 1.?

hi there,
recently, we've come across a lot of advice to only use replicated rados
pools as default- (ie: root-) data pools for cephfs¹.
unfortunately, we either skipped or blatantly ignored this advice while
creating our cephfs, so our default data pool is an erasure coded one
with k=2 and m=4,
We've been running into a strange problem repeating every day or so with
a specific HPC job on a Mimic cluster (13.2.8) using ceph-fuse
(14.2.7). It seems like some cephfs clients are stuck (perhaps
deadlocked) trying to access a file and are not making progress.
Ceph reports the following
Yes in the end we are in the process of doing it, but we first
upgraded the MDSs which worked fine and it solved the problem we had
with CephFS.
Best,
Martin

Hi Patrick,
we have performed a minor upgrade to 12.2.13 which resolved the issue.
We think it was the following bug:

Have you tried dumping the mempools? The memory autotuner will grow or
shrink the bluestore caches to try to keep the total OSD process mapped
memory just under the target. If there's a memory leak or some other
part of the OSD is using more memory than it should, it will shrink the
caches

I made a bucket named "test_lc" and ran `s3cmd expire
--expiry-date=2019-01-01 s3://test_lc` to set the lifecycle (2019-01-01 is
earlier than current date so every object will be removed).
Then I ran `radosgw-admin
Hi,
The Ceph Berlin MeetUp is a community organized group that met
bi-monthly in the past years: https://www.meetup.com/Ceph-Berlin/
The meetups start at 6 pm and consist of one presentation or talk and a

Just upgrade your cluster to 12.2.13. Luminous is safe and very stable.
