Hey Alexandre,
Sorry for the late reply here. I believe Anthony can give you a response on why
we chose a matrix rating scale type instead of rank.

Don't do this if you have a large cache. It will make your MDS
unresponsive and replaced by a standby if available. There is a PR to
fix this:
Thanks Dan and Anthony your suggestions have pointed me in the right
direction. Looking back through the logs at when the first error was
detected I found this:

Unless there's some magic I'm unaware of, there is no way to
dynamically change this. Each OSD must be recreated with the new
min_alloc_size setting. In
Anyone running octopus (v15)? Can you please share your experience of
radosgw-admin performance?
A simple 'radosgw-admin user list' took 11 minutes; if I use a v13.2.4
radosgw-admin, it can be finished in a few seconds.
This sounds like a performance regression to me. I've already filed a bug
Nope !

Hi all,
I have a cluster with 116 disks (24 new disks of 16TB added in december
and the rest of 8TB) running nautilus 14.2.16.
I moved (8 month ago) from crush_compat to upmap balancing.
But the cluster seems not well balanced, with a number of pgs on the 8TB
disks varying from 26 to 52 ! And
Thank you. This helps a lot.

Usually the ceph.log prints the reason for the inconsistency when it
is first detected by scrubbing.

Hi Chris
Having also recently started exploring Ceph. I too happened upon this problem.
I found that terminating the command witch ctrl-c seemed to stop the looping.
Which btw. also happens on all other mgr instances in the cluster.

Doing some more testing.
I can demote the rbd image on the primary, promote on the secondary and the
image looks great. I can map it, mount it, and it looks just like it should.
However, the rbd snapshots are still unusable on the secondary even when
promoted. I went as far as taking a 2nd
Hi,
In our experience failovers are largely transparent if the mds has:
mds session blacklist on timeout = false
mds session blacklist on evict = false
And clients have
client reconnect stale = true

Hello fellow CEPH-users,
currently we are updating our CEPH(14.2.16) and making changes to some
config settings.
TLDR: is there a way to make a graceful MDS active node shutdown without
loosing the caps, open files and client connections? Something like
handover active state, promote standby
