CEPH 16.2.4. I was having an issue where I put a server into maintenance mode and after
doing so, the containers for the iSCSI gateway were not running, so I decided to do a
redeploy of the service. This caused all the servers running iSCSI to get in a state where
it looks like ceph orch was trying to delete the container, but it was stuck. My only
recourse was to reboot the servers. I ended up doing a ‘ceph orch rm iscsi.iscsi’ to just
remove the services and then tried to redeploy. When I do this, I’m seeing the following
in the cephadm logs on the servers where the iscsi gateway is being deployed:
2021-06-01 19:48:15,110 INFO Deploy daemon iscsi.iscsi.cxcto-c240-j27-02.zeypah ...

Later in the logs I see:

Obviously no such object because the container creation failed.
If I try to run that command that is in the logs manually, I get:
[root@cxcto-c240-j27-02 ceph]# /bin/docker run --rm --ipc=host --net=host --entrypoint
stat --init -e

-c %u %g /var/lib/ceph
stat: cannot stat '%g': No such file or directory
167
So the 167 seems to line up with what’s showing up in the script. I’m not clear on what
the deal is with the %g. What is supposed to be in that placeholder? Any thoughts on why
this is failing?
Right now all my iSCSI gateways are down and basically my whole environment is down as a
result 🙁
