Hi Daniel,
indeed, this is the root cause, but I do not understand what's wrong
here and the real cause of the failure. Since I was suspicious about the
ceph.conf setup I've already checked that it all works, and it does
indeed. I can issue ceph -s or rados df without any problem.
Here I give you a couple of examples:
$ ceph -s
cluster aac2c2c4-5953-44d7-b90c-9922a8ccd77a
health HEALTH_OK
monmap e4: 3 mons at
{mon1=<ipmon1>:6789/0,mon2=<ipmon1>:6789/0,mon3=<ipmon3>:6789/0}
election epoch 124, quorum 0,1,2 mon3,mon2,mon1
fsmap e42: 1/1/1 up {0=mds1=up:active}, 1 up:standby
mgr no daemons active
osdmap e16477: 54 osds: 52 up, 52 in
flags sortbitwise,require_jewel_osds,require_kraken_osds

Any other hint? Of course, having more verbosity from the rados init
would be very helpful, but even with FULL_DEBUG I always get the same
messages and nothing more.
Thanks,
Alessandro
