Unfortunately Ceph 16.2.4 is still not working for us.  We continue to have
issues where the 26th OSD is not fully created and started.  We've
confirmed that we do get the flock as described in:

https://tracker.ceph.com/issues/50526

-----

*I have verified in our labs a way to reproduce easily the problem:*

*0. Please stop the cephadm orchestrator:*


*In your bootstrap node:*

*# cephadm shell
# ceph mgr module disable cephadm
*

*1. In one of the hosts where you want to create osds and you have a big
amount of devices:*


*See if you have a "cephadm" filelock:for example:*

*# lslocks | grep cephadm
python3         1098782  FLOCK   0B WRITE 0     0   0
/run/cephadm/9fa2b396-adb5-11eb-a2d3-bc97e17cf960.lock
*

*if that is the case. just kill the process to start with a "clean"
situation*

*2. Go to the folder: /var/lib/ceph/<your_ceph_cluster_fsid>*

*you will find there a file called "cephadm.xxxxxxxxxxxxxx".*


*execute:*

*# python3 cephadm.xxxxxxxxxxxxxx ceph-volume inventory
*

*3. If the problem is present in your cephadm file, you will have the
command blocked and you will see again a cephadm filelock*

*4. In the case that the modification was not present. Change your
cephadm.xxxxxxxxxx file to include the modification I did (is just to
remove the verbosity parameter in the call_throws call)*

*https://github.com/ceph/ceph/blob/2f4dc3147712f1991242ef0d059690b5fa3d8463/src/cephadm/cephadm#L4576*
<https://github.com/ceph/ceph/blob/2f4dc3147712f1991242ef0d059690b5fa3d8463/src/cephadm/cephadm#L4576>

*go to step 1, to clean the filelock and try again... with the modification
in place it must work.*

*-----*

For us, it takes a few seconds but then the manual execution does come
back, and there are no file locks, however we remain unable to add any
further OSDs.

Furthermore, this is happening as part of the creation of a new Pacific
Cluster creation post bootstrap and adding one OSD daemon at a time and
allowing each OSD to be created, set in, and brought up.

How is everyone else managing to get past this, or are we the only ones
(aside from David) using >25 OSDs per host?

Our luck has been the same with 15.2.13 and 16.2.4, and using both Docker
and Podman on Ubuntu 20.04.2

Thanks,
Marco
