Re: Module rbd not found on Ubuntu 13.04

[Prasanna Gholap <prasanna@xxxxxxxx>]

Hi,

I don't have rbd module in given location
ubuntu@ubuntu:~$ ls /lib/modules/3.8.0-19-generic/kernel/drivers/block
cryptoloop.ko  floppy.ko  nbd.ko
ubuntu@ubuntu:~$ modinfo rbd
ERROR: Module rbd not found.

By the link about aws, rbd.ko isn't included yet in linux aws . I'll try to build the kernel manually and proceed for rbd.

Thanks for your help.

Remove on AWS images ?

For me, the module is here (ubuntu 13.04) :
$ ls /lib/modules/$(uname -r)/kernel/drivers/block/

$ modinfo rbd

Hi Laurent,

Thanks for reply. I checked in my machine:
ubuntu@ubuntu:~$ grep CONFIG_BLK_DEV_RBD /boot/config-3.8.0-19-generic
CONFIG_BLK_DEV_RBD=m

It is not a custom kernel. It is an AWS instance.

    You can verify that rbd module is enable in your kernel config :
    $ grep CONFIG_BLK_DEV_RBD /boot/config-3.8.0-19-generic
    CONFIG_BLK_DEV_RBD=m
