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

Make sure it's 3.16.3 or later. Thanks, Ilya |
