A while ago - before ceph balancer - probably on Jewel
We had a bunch of disks with different re-weights to help control pg
We upgraded to luminous
All our disks are the same, so we set them all back to 1.0 then let them fill
accordingly
Then ran balancer about 4-5 times, letting each run finish
I talked to some guys on IRC about going back to the non-1 reweight
OSD's and setting them to 1.
I went from a standard deviation of 2+ to 0.5.
Awesome.

If I understand that command correctly, it's tells MDS 'c' to disappear, the
same as rebooting would, right?
Let me just clarify something then...
When I run ceph fs dump I get the following:
110248: [v2:10.2.80.10:6800/1470324937,v1:10.2.80.10:6801/1470324937] 'S700041'

Hi all,
I just want to report that I was able to recover from the incomplete PG after
exporting the PGs and using the dangerous
osd_find_best_info_ignore_history_les option on the appropriate OSDs :) Things
seem okay for now, fingers crossed.
When marking hit set archive objects lost, I was u
Thanks for pointing that out, I must have missed it searching earlier.
I'll look forward to upgrading when 14.2.8 comes out and see if that
addresses the issue.

All;
We just started really fiddling with CephFS on our production cluster (Nautilus
- 14.2.5 / 14.2.6), and I have a question...
Is there a command / set of commands that transitions a standby-replay MDS
server to the active role, while swapping the active MDS to standby-replay, or
even just
Hi all,
I'm looking for the best way to merge/remap existing host buckets into one.
I'm running a Ceph Nautilus cluster used as a Ceph Cinder backend with 2
pools "volume-service" and "volume-recherche" both with dedicated OSDs :

Hi everyone,
we currently have 6 OSDs with 8TB HDDs split across 3 hosts.
The main usage is KVM-Images.
To improve speed we planned on putting the block.db and WAL onto NVMe-SSDs.
The plan was to put 2x1TB in each host.
