Hello Eugen,
recovery and rebalancing was finished however now all PGs show missing OSDs.
Everything looks like the PGs are missing OSDs although it finished
correctly.
As if we shut down the servers immediately.
But we removed the nodes the way it is described in the documentation.
We just added new disks and they join the cluster immediately.
So the old OSDs removed from the cluster are available, I restored
OSD.40 but it does not want to join the cluster.
Following are the outputs of the mentioned commands:
ceph -s

Hi,
Yes, we drained the nodes. It needed two weeks to finish the
process, and yes, I think this is the root cause.
So we still have the nodes but when I try to restart one of those
OSDs it still cannot join:
if the nodes were drained successfully (can you confirm that all
PGs were active+clean after draining before you removed the nodes?)
then the disks on the removed nodes wouldn't have any data to bring
back. The question would be, why do the remaining OSDs still
reference removed OSDs. Or am I misunderstanding something? I think
it would help to know the whole story, can you provide more
details? Also some more general cluster info would be helpful:
$ ceph -s
$ ceph osd tree
$ ceph health detail

Hello Eugen,
thank you. Yesterday I thought: Well, Eugen can help!
Yes, we drained the nodes. It needed two weeks to finish the

OSDs it still cannot join:

Same messages on all OSDs.
We still have some nodes running and did not restart those OSDs.

Hi,
can you share more details what exactly you did? How did you
remove the nodes? Hopefully, you waited for the draining to
finish? But if the remaining OSDs wait for removed OSDs it sounds
like the draining was not finished.
Zitat von Malte Stroem <malte.str...@gmail.com>:
Hello,
we removed some nodes from our cluster. This worked without problems.
Now, lots of OSDs do not want to join the cluster anymore if we
reboot one of the still available nodes.
It always runs into timeouts:
--> ceph-volume lvm activate successful for osd ID: XX
monclient(hunting): authenticate timed out after 300
MONs and MGRs are running fine.
Network is working, netcat to the MONs' ports are open.
Setting a higher debug level has no effect even if we add it to
the ceph.conf file.
The PGs are pretty unhappy, e. g.:
7.143 87771 0 0 0
0 314744902235 0 0 10081 10081
down 2023-06-20T09:16:03.546158+0000 961275'1395646
961300:9605547 [209,NONE,NONE] 209 [209,NONE,NONE]
209 961231'1395512 2023-06-19T23:46:40.101791+0000
961231'1395512 2023-06-19T23:46:40.101791+0000
PG query wants us to set an OSD lost however I do not want to do this.
OSDs are blocked by OSDs from the removed nodes:
ceph osd blocked-by
osd num_blocked
152 38
244 41
144 54
...
We added the removed hosts again and tried to start the OSDs on
this node and they also failed into the timeout mentioned above.
This is a containerized cluster running version 16.2.10.
Replication is 3, some pools use an erasure coded profile.
Best regards,
Malte
