Hello Mario,
This kind of problem usually happens for following reasons:
1-) One of the OSD nodes has network problem.
2-) Disk failure
3-) Not enough resource for OSD nodes
4-) Slow OSD Disks
This happened before me. The problem was network cable problem. As soon as I replaced the cable, everything was fine and dandy.

1 osds have slow requests
Problem is that when I try to read or write to pool "rbd" (where I have all
my virtual machines) ceph starts to log "slow reads" and system hungs.
If in the same cluster I create another pool and inside it I create an
image I can read and write correctly (and fast) so it seems the cluster is
working and only the pool is not working.
Can you help me?
Thanks,
Mario
