Hi,
I'm using RBD to store VM image and they're accessed through the
kernel client (xen vms).
In the client dmesg log, I see periodically :
Nov 29 10:46:48 b53-04 kernel: [160055.012206] libceph: osd8
10.208.2.213:6806 socket closed
Nov 29 10:46:48 b53-04 kernel: [160055.013635] libceph: osd8
10.208.2.213:6806 socket error on read
And in the matching osd log I find :
2012-11-29 10:46:48.130673 7f6018127700 0 -- 192.168.2.213:6806/944

Note that this doesn't seem to pose any operational issue (i.e. it
works ... when it retries it eventually connects).
My configuration: The client currently runs on a debian wheezy and use
a custom built 3.6.8 kernel that contains all the latest ceph rbd
patch AFAIK but the problem was also showing up with earlier kernel
versions. The cluster is a 0.48.2 running on Ubuntu 12.04 LTS.
Cheers,
Sylvain
