Ceph on RHEL 7 with multiple OSD's

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

It it looks like your osd.0 is down and you only have one osd left (osd.1) which would explain why the cluster cannot get to a healthy state. The "size 2" in  "pool 0 'data' replicated size 2 ..." means the pool needs at least two OSDs up to function properly. Do you know why the osd.0 is not up ?

Cheers
