All,
I have a small ceph cluster with 4 OSDs and 3 MONs on 4 systems.
I was rsyncing about 50TB of files and things get very slow. To the point I
stopped the rsync, but even with everything stopped, I see:
health HEALTH_WARN
80 requests are blocked > 32 sec
The number was as high as 218, but they seem to be draining down.
I see no issues on any of the systems, CPU load is low, memory usage is low.
How do I go about finding why a request is blocked for so long? These have been
hitting >500 seconds for block time.
