In fact, it's curious:
~# ceph mon dump
dumped monmap epoch 3
epoch 3
fsid f875b4c1-535a-4f17-9883-2793079d410a

~# ceph tell mon.1 version
ceph version 9.2.0 (17df5d2948d929e997b9d320b228caffc8314e58)
~# ceph tell mon.2 version
ceph version 9.2.0 (17df5d2948d929e997b9d320b228caffc8314e58)
~# ceph tell mon.3 version
Error ENOENT: problem getting command descriptions from mon.3
[2] root@ceph03 06:35 ~
~# ceph tell mon.0 version
ceph version 9.2.0 (17df5d2948d929e997b9d320b228caffc8314e58)
Concerning monitors, I have this in my ceph.conf:
[mon.1]
host = ceph01
mon addr = 10.0.2.101
[mon.2]
host = ceph02
mon addr = 10.0.2.102
[mon.3]
host = ceph03
mon addr = 10.0.2.103
So the ID of my monitors are 1, 2, 3. But there is a little
problem because I have :
~# ceph tell mon.0 version
ceph version 9.2.0 (17df5d2948d929e997b9d320b228caffc8314e58)
So what is this mon.0 ??
