Well,I used 'systemctl restart ceph-mon@qbs-monitor-online009-hbaz1.service' and 4 MDSs did update to v12.2.9 from 12.2.8. The mons'version is v12.2.9.Actually ,the mgr and the OSDs' version is v12.2.9 now. But the mon still failed What I am confused about is that when I used 'ceph-mds --version' at each MDS ,it returned 'v12.2.9',but when I used 'ceph versions', it seems that I have 5 MDSs, and one's version is 12.2.8.( I only have 4 mds in fact) Thanks Loukaiyi -----Original Message----- From: Patrick Donnelly [mailto:pdonnell@xxxxxxxxxx] Sent: Thursday, November 22, 2018 2:17 AM To: 楼锴毅 Cc: Ceph Users Subject: Re: mon:failed in thread_name:safe_timer On Tue, Nov 20, 2018 at 6:18 PM 楼锴毅 <loukaiyi_sx@xxxxxxxx> wrote: > Hello > Yesterday I upgraded my cluster to v12.2.9.But the mons still failed > for the same reason.And when I run 'ceph versions', it returned " > "mds": { > "ceph version 12.2.8 (ae699615bac534ea496ee965ac6192cb7e0e07c0) luminous (stable)": 1, > "ceph version 12.2.9 (9e300932ef8a8916fb3fda78c58691a6ab0f4217) luminous (stable)": 4 > }, > " > But actually I only have four MDS , and their versions are all v12.2.9 .I am confused about it. How did you restart the MDSs? If you used `ceph mds fail` then the executable version (v12.2.8) will not change. Also, the monitor failure requires updating the monitor to v12.2.9. What version is the mons? -- Patrick Donnelly _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
