Hello!
I'm not much experiensed in ceph troubleshouting that why I ask for help.
I have multiple warnings coming from zabbix as a result of ceph -s
REQUEST_SLOW: HEALTH_WARN : 21 slow requests are blocked > 32 sec
I don't see any hardware problems that time.
I'm able to find the same strings in ceph.log and ceph-mon.log like
2018-05-07 12:37:57.375546 7f3037dae700 0 log_channel(cluster) log
[WRN] : Health check failed: 12 slow requests are blocked > 32 sec
(REQUEST_SLOW)
Now It's important to find out the root of the problem.
How to find out:
1. which OSDs are affected
2. which particular requests were slowed and blocked?
I assume I need more detailed logging - how to do that?
Appreciate your help.
