You could try flushing out the FileStore journals off the SSD and creating
new ones elsewhere (eg, colocated). This will obviously have a substantial
impact on performance but perhaps that’s acceptable during your upgrade
window?

Hi Erik,
The thing is that the rbd-mirror service uses the /etc/sysconfig/ceph file to
determine which configuration file to use (from CLUSTER_NAME). So you need to
set this to the name you chose for rbd-mirror to work. However setting this
CLUSTER_NAME variable in /etc/sysconfig/ceph makes it

I think I have to re-install ceph v13 from scratch then.

If, in the above case, osd 13 was not too busy to respond (resource
shortage) then you need to find out why else osd 5, etc. could not
contact it.

Hi,
I have upgraded to 12.2.7 , 2 weeks ago,
and I don't see anymore memory increase ! (can't confirm that it was related
to your patch).
Thanks again for helping !

I looked at this a bit and it turns out anybody who's already in the slack
group can invite people with unrestricted domains. I think it's just part
of Slack that you need to specify which domains are allowed in by default?

There is an undocumented part of the cephx authentication framework called
the 'auid' (auth uid) that assigns an integer identifier to cephx users
and to rados pools and allows you to craft cephx capabilities that apply
to those pools. This is leftover infrastructure from an ancient time in

TBH, I'm not expert enough on the kernel-side implementation of fuse

Hi John,
With regard to memory pressure; Does the cephfs fuse client also cause a
deadlock - or is this just the kernel client?
We run the fuse client on ten OSD nodes, and use parsync (parallel
rsync) to backup two beegfs systems (~1PB).
Ordinarily fuse works OK, but any OSD problems can cause
You can only try to remount the cephs dir. It will probably not work,
giving you I/O Errors, so the fallback would be to use a fuse-mount.
If I recall correctly you could do a lazy umount on the current dir (umount
-fl /mountdir) and remount it using the FUSE client.
it will work for new sessions
Hi,
Is there any other way excpet rebooting the server when the client hangs?
If the server is in production environment, I can't restart it everytime.

I'm not using this feature, so maybe I'm missing something, but from
the way I understand cluster naming to work...
I still don't understand why this is blocking for you. Unless you are
attempting to mirror between two clusters running on the same hosts
(why would you do this?) then systemd
Hi Zhenshi,
if you still have the client mount hanging but no session is connected, you
probably have some PID waiting with blocked IO from cephfs mount.
I face that now and then and the only solution is to reboot the server, as
you won't be able to kill a process with pending IO.

Hi Webert,
That command shows the current sessions, whereas the server which I get the
files(osdc,mdsc,monc) disconnect for a long time.
So I cannot get useful infomation from the command you provide.

Hi again Frederic,
It may be worth looking at a recovery sleep.
osd recovery sleep
Description:
Time in seconds to sleep before next recovery or backfill op. Increasing this
value will slow down recovery operation while client operations will be less
impacted.
Type:
Float
Default:
0
osd
You could also see open sessions at the MDS server by issuing `ceph daemon
mds.XX session ls`

So your OSDs are really too busy to respond heartbeats.
You'll be facing this for sometime until cluster loads get lower.
I would set `ceph osd set nodeep-scrub` until the heavy disk IO stops.
maybe you can schedule it for enable during the night and disabling in the
morning.

Thx for the command line, I did take a look too it what I don’t really know
what to search for, my bad….
All this flapping is due to deep-scrub when it starts on an OSD things start to
go bad.
I set out all the OSDs that were flapping the most (1 by 1 after rebalancing)
and it looks better

That message is harmless -- it just means that the userspace mount.ceph

Hi All, exactly the same story today, same 8 OSDs and a lot of garbage
collection objects to process
Below is the number of "cls_rgw.cc:3284: gc_iterate_entries end_key="

Do you see "internal heartbeat not healthy" messages in the log of the
osd that suicides?

What is the load like on the osd host at the time and what does the
disk utilization look like?
Also, what does the transaction look like from one of the osds that
sends the "you died" message with debugging osd 20 and ms 1 enabled?

Thank you for your suggestion, tried it, really seems like the other
osds think the osd is dead(if I understand this right), however the
networking seems absolutely fine between the nodes(no issues in graphs
etc).
