Hello list,
we have found that the active mgr process in our 3-node CEPH cluster
takes a lot of memory. After start the memory usage is constantly
increasing. After 6 days the process takes ~67GB:
~# ps -p 7371 -o rss,%mem,cmd
RSS %MEM CMD
71053880 26.9 /usr/bin/ceph-mgr -n mgr.hostname.nvw
Hello list,
forget to mention the CEPH version:
17.2.6 (d7ff0d10654d2280e08f1ab989c7cdf3064446a5)
quincy (stable)

Hi,
there was a change introduced [1] for cephadm to use dashes for
container names instead of dots. That still seems to be an issue
somehow, in your case cephadm is complaining about the missing
directory:
/var/lib/ceph/d0a3b6e0-d2c3-11ed-be05-a7a3a1d7a87e/grafana-fl31ca104ja0201/unit.run
Hi,
can the cephfs "max_file_size" setting be changed at any point in the
lifetime of a cephfs?
Or is it critical for existing data if it is changed after some time? Is
there anything to consider when changing, let's say, from 1TB (default)
to 4TB ?

Hi,
there was a thread [1] just a few weeks ago. Which mgr modules are
enabled in your case? Also the mgr caps seem to be relevant here.

Good morning Eugen!
Thank you, this allowed me to succcessfully migrate my OSDs to ports
above 6830. This in turn prevents the conflict with slurmd.
Cordially,

I found that I could get much more aggressive with the
osd_mclock_cost_per_byte_usec_hdd values if my
osd_mclock_max_capacity_iops_hdd numbers were set to sane values. If I used
the (very wrong) default calculated values I would start getting slow ops.

There are tags for placement, so any user that has the tag is allowed to access
the placement.
But I can't find how to do it for storage class?
Anyone have any ideal? Thanks.

Hi Venky,
thank you for your help. We managed to shut down mds.1:
We set "ceph fs set max_mds 1" and waited for about 30 minutes. In the first
couple minutes, strays were migrated from mds.1 to mds.0. After this, the stray
export hung. The mds.1 remained in the state_stopping. After about 30 min
In addition, i would like to mention that the number of "strays_created"
also increases after this action, but the number of num_strays is lower
now. If desired, we can provide debug logs from mds at the time the mds
was in stopping state and we did a systemctl restart mds1.

Hello Igor,
just reporting, that since last restart (after reverting changed values
to their defaults) the performance hasn't decreased (and it's been over
two weeks now). So either it helped after all, or the drop is caused
by something else I'll yet have to figure out.. we've automated the test

Just to be clear, these were the settings that you changed back to the
defaults?
Non-default settings are:

"mon": "4294967296",
"final": "4294967296"

Thanks for replying, Greg. I'll give you a detailed sequence I did on the
upgrade at below.
Step 1: upgrade ceph mgr and Monitor --- reboot. Then mgr and mon are all up
running.
Step 2: upgrade one OSD node --- reboot and OSDs are all up.
Step 3: upgrade a second OSD node named OSD-node2. I did
