Hi,

I have a Ceph cluster and I am trying to create a block device. I execute the 
following command, and get errors:

èsudo rbd map cephblockimage --pool rbd -k /etc/ceph/ceph.client.admin.keyring

libkmod: ERROR ../libkmod/libkmod.c:556 kmod_search_moddep: could not open 
moddep file '/lib/modules/3.18.0-02094-gab62ac9/modules.dep.bin'

modinfo: ERROR: Module alias rbd not found.

modprobe: ERROR: ../libkmod/libkmod.c:556 kmod_search_moddep() could not open 
moddep file '/lib/modules/3.18.0-02094-gab62ac9/modules.dep.bin'

rbd: modprobe rbd failed! (256)

What distro/release is this?

Does /lib/modules/3.18.0-02094-gab62ac9/modules.dep.bin exist?

Can you run the command as root?


Need help with what is wrong. I installed the Ceph package on the machine where 
I execute the command. This is on ARM BTW.  Is there something I am missing?

I am able to run Object storage and rados bench just fine on the cluster.

Thanks

Pankaj
