Hi,
I ran a small test two node ceph cluster - 12.2.0 version. It has
28 osds, 1 mon and 2 mgr. It runs fine, however I noticed this
strange thing in output of ceph versions command:
# ceph versions
{
"mon": {
"ceph version 12.2.0
(32ce2a3ae5239ee33d6150705cdb24d43bab910c) luminous (rc)": 1
},
"mgr": {
"ceph version 12.2.0
(32ce2a3ae5239ee33d6150705cdb24d43bab910c) luminous (rc)": 1,
"unknown": 1
},
"osd": {
"ceph version 12.2.0
(32ce2a3ae5239ee33d6150705cdb24d43bab910c) luminous (rc)": 28
},
"mds": {},
"overall": {
"ceph version 12.2.0
(32ce2a3ae5239ee33d6150705cdb24d43bab910c) luminous (rc)": 30,
"unknown": 1
}
}
As you can see one ceph manager is in unknown state. Why is that
? FYI, I checked rpms versions and did a restart of all mgr and I
still get the same result.
Kind regards,
Piotr Dzionek
