Say one is forced to move a production cluster (4 nodes) to a different
datacenter. What options do I have, other than just turning it off at
the old location and on on the new location?
Maybe buying some extra nodes, and move one node at a time?

Osd's do not even use bonding effenciently. If it were to use 2 links
concurrently it would be a lot better.

Hi Philipp
You can optimize ceph-osd for this of course. It would benefit people
that like to use the 1Gbit connections. I can understand putting time
into it now does not make sense because of the availability of 10Gbit.
However, I do not get why this was not optimized already 5 or 10 years
ago.

I didn't have such drop in performance testing 'rados bench 360 write -p
rbd' on 3x replicated (slow)hdd pool. Sort of near the average,
sometimes drops to 90. But I guess the test hits than an osd that is
scrubbing and being used by other processes.

ceph mgr module ls does not show the rbd_support, should this not be
listed?

Say I think my cephfs is slow when I rsync to it, slower than it used to
be. First of all, I do not get why it reads so much data. I assume the
file attributes need to come from the mds server, so the rsync backup
should mostly cause writes not?
I think it started being slow, after enabling s
been looking at the mds with 'ceph daemonperf mds.a'

I have default centos7 setup with nautilus. I have been asked to install
5.5 to check a 'bug'. Where should I get this from? I read that the

How do you check if you issued this command in the past?

Hi Peter,
could be a totally different problem but did you run the command "ceph
osd require
-users] centos7 / nautilus where to get kernel 5.5
from?

cephfs is considered to be stable. I am using it with only one mds for
2-3 years in low load environment without any serious issues.
