I tried reproducing this (admittedly with a downstream SUSE build), and TERM seemed to have no effect, while KILL did result in ganesha stopping, but it was restarted automatically after a couple of seconds. One possible difference is that the downstream SUSE deployment passes --container-init to `cephadm bootstrap`. Not sure if that makes a difference here.

The two sets of logs in the previous comment look pretty much identical to me, aside from the various IDs.

How was your test cluster deployed (vstart/cstart/something else)? I'd like to see if I'm able to reproduce myself with the latest upstream.

Thanks Tim for looking into it. I tested using vstart cluster.

Sebastian, do we have documentation somewhere about which situations cephadm will restart services? I think there needs to be a clear outline of what triggers restart of a service.

(I think this is a somewhat unfortunately situation as cephadm wasn't necessarily intended to provide HA via respin of services; services like MDS/OSDs already provide HA as part of their protocol. Still, something needs to be done for NFS.)
