ThankYou Ilya!
I have built Centos6.5 kernel 3.6.3 using source linux-3.16.3.tar.gz from
www.kernel.org
[root@root ~]# uname -a
Linux root 3.16.3 #1 SMP Fri Oct 10 06:48:44 PDT 2014 x86_64 x86_64 x86_64
GNU/Linux
The kernel modules (includes rbd.ko hopefully…are still compiling….
Since building a FedoraCore20 Client hosts is much faster that building a
kernel and modules from sources.
I have built a FedoraCore20 Client hosts machine and below are the
results…Enjoy!!:
[root@localhost ceph]# uname -a
Linux localhost.localdomain 3.16.3-200.fc20.x86_64 #1 SMP Wed Sep 17 22:34:21
UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
Created RBD:
[root@root ceph]# rbd create rbd1 --size 40960 --pool vsmpool_hp1 -id admin
[root@root ceph]# rbd create rbd1 --size 40960 --pool vsmpool_perf1 -id admin
List the RBD’s:
[root@localhost ceph]# rbd ls vsmpool_hp1
rbd1
[root@localhost ceph]# rbd ls vsmpool_perf1
rbd1
[root@localhost ceph]# rbd map vsmpool_hp1/rbd1 --id admin
Successful…
Note: this is where we have an I/O error in Centos6.5 kernel 3.10.25
[root@localhost ceph]# rbd showmapped

Format the RBD:

I’ll share results of centos6.5 running kernel 3.16.3 once module finish
compiling….
Enjoy!!!

Make sure it's 3.16.3 or later.
Thanks,
