Hi Patrick,

Hi,

After a power outage on my test ceph cluster, 2 osd fail to restart.  The log file show:

This is not critical as it is a test cluster and it is actually rebalancing on other osd but I would like to know how to return to HEALTH_OK status.

Smartctl show the HDD are OK.

So is there a way to recover the osd from this state ? Version is 15.2.17 (juste moved from 15.2.13 to 15.2.17 yesterday, will try to move to latest versions as soon as this problem is solved)

Thanks

Patrick
