image map failed

[Ishmael Tsoaela <ishmaelt3@xxxxxxxxx>]

Hi All,

I  have created an image but cannot map the image, anybody know what could be the problem:

sudo rbd map data/data_01

rbd: sysfs write failed

RBD image feature set mismatch. You can disable features unsupported by the kernel with "rbd feature disable".

In some cases useful info is found in syslog - try "dmesg | tail" or so.

rbd: map failed: (6) No such device or address

cluster_master@nodeC:~$ dmesg |tail
