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
