Dear list,
After an upgrade from package-based cluster running 16.2.9, to cephadm
with docker (following
https://docs.ceph.com/en/pacific/cephadm/adoption/), I have a strange
discrepancy between the running versions:
/ceph versions//
//{//
// "mon": {//
// "ceph version 16.2.9
(4c3647a322c0ff5a1dd2344e039859dcbd28c830) pacific (stable)": 3//
// },//
// "mgr": {//
// "ceph version 16.2.9
(4c3647a322c0ff5a1dd2344e039859dcbd28c830) pacific (stable)": 2//
// },//
// "osd": {//
// "ceph version 16.2.9
(4c3647a322c0ff5a1dd2344e039859dcbd28c830) pacific (stable)": 181//
// },//
// "mds": {//
// "ceph version 16.2.5-387-g7282d81d
(7282d81d2c500b5b0e929c07971b72444c6ac424) pacific (stable)": 3//
// },//
// "overall": {//
// "ceph version 16.2.5-387-g7282d81d
(7282d81d2c500b5b0e929c07971b72444c6ac424) pacific (stable)": 3,//
// "ceph version 16.2.9
(4c3647a322c0ff5a1dd2344e039859dcbd28c830) pacific (stable)": 186//
// }//
//}//
/
I tried asking cephadm to upgrade to 16.2.9 ( /ceph orch upgrade start
--ceph-version 16.2.9/ ), but it only seems to cycle between the active
managers (about every 15 to 20s), without doing anything more. Here is a
part of the logs from one of the MGR:
/7f599cbe9700 0 [cephadm INFO cephadm.upgrade] Upgrade: Need to upgrade
myself (mgr.inf-ceph-mds)//
//7f599cbe9700 0 log_channel(cephadm) log [INF] : Upgrade: Need to
upgrade myself (mgr.inf-ceph-mds)//
//7f599cbe9700 0 [cephadm INFO cephadm.services.cephadmservice] Failing
over to other MGR//
//7f599cbe9700 0 log_channel(cephadm) log [INF] : Failing over to other
MGR//
/
Something strange as well, it seems that it is looking for more daemons
(191) to upgrade than the 189 (from 186 in 16.2.9 and 3 in 16.2.5-387-nnnn):
/ceph orch upgrade status//
//{//
// "target_image":
"quay.io/ceph/ceph@sha256:5d3c9f239598e20a4ed9e08b8232ef653f5c3f32710007b4cabe4bd416bebe54",//
// "in_progress": true,//
// "services_complete": [//
// "mgr",//
// "mon"//
// ],//
// "progress": "187/191 daemons upgraded",//
// "message": ""//
//}/
So I have two questions:
1. Do you have any pointers as to where I could look for information on
what is going on (or not, actually)?
2. Would it be safe to stop the upgrade, and ask it to safely move to
17.2.1 instead?
Best regards,
Stephane
