Hi,
while doing my first tests with ceph i'm always struggling about these
kernel messages:

new mon
[ 472.226073] libceph: mon0 10.0.255.100:6789 session established
Always while stress testing the session to the mon's got lost. Any ideas?
These aren't a problem - it's just the connection to a monitor being
lost, and the client connecting to another one.
But what is causing this? I'm also seeing:
[ 623.554698] ceph: mds0 caps stale
[ 650.190504] ceph: mds0 caps renewed
My biggest problem is that random reads and writes are awfully slow.
