I installed ceph 0.56 on Red Hat Enterprise Linux Server release 6.0 (Santiago). It works well.
but, when I follow the " block device quick start", I get a problem.
[root@crt24 ceph]# rbd create foo --size 4096
[root@crt24 ceph]# rados ls -p rbd
foo.rbd
rbd_directory
[root@crt24 ceph]# modeprobe rbd
--------------------------------------------------------------------------------------------------
Then. An error occurred!
--------------------------------------------------------------------------------------------------
[root@crt24 ceph]# rbd map foo --pool rbd --name client.admin
rbd: /sys/bus/rbd/add does not exist!
Did you run 'modprobe rbd' or is your rbd module too old?
rbd: add failed: (2) No such file or directory
--------------------------------------------------------------------------------------------------
So I check lsmod first. but no" rbd moudule" found.
--------------------------------------------------------------------------------------------------
[root@crt24 fs]# lsmod |grep rbd
[root@crt24 fs]#
--------------------------------------------------------------------------------------------------
Then, I try to find rbd.ko. but no rbd.ko too.
--------------------------------------------------------------------------------------------------
[root@crt24 ceph]# cd /lib/modules/2.6.34.14/kernel/drivers/block
[root@crt24 fs]# ls
aoe cciss.ko cryptoloop.ko drbd nbd.ko sx8.ko umem.ko
brd.ko cpqarray.ko DAC960.ko floppy.ko pktcdvd.ko ub.ko
So my idea is that recompile the kernel. And compile the RBD module into the kernel.
While, unfortunately，I can't find the RBD module when I “make menuconfig”.
Now, I want to know that Is there another solution to add the RBD module,
or what I exactly went wrong！ thanks a lot！
