Hi,
We operate a Ceph Nautilus (15.2.13) cluster with ~400 OSDs and 4
which one is it Nautilus (14.2.X) or Octopus (15.2.X)?
A few months back a similar question was asked for multiple rgw
daemons per host [1] and there was no real answer, only that the docs
[2] are ahead of the implementation. I don't think there's a solution
for multi-mds-per-node for cephadm yet.

Zitat von "McLennan, Kali A." <kali_ann@xxxxxx>:
We operate a Ceph Nautilus (15.2.13) cluster with ~400 OSDs and 4
dedicated MDS servers. Currently we are running 2 active, 2 standby
MDS, but would like to scale the MDS containers horizontally on each
of the physical MDS servers.
The MDS servers in question have dual 16-core Xeon processors with
128GB of physical RAM. Active resource utilization is around the
expected 1-core and 8GB of RAM based on MDS cache settings. Ceph
documentation from prior to cephadm suggest to scale the number of
MDS daemons per node, but attempts to work out how to do this on a
containerized cluster have not been productive. Has anyone worked
out how to run multiple MDS containers on the same physical server?
Thanks!
