Hi all,
I was trying out openvz and ended up in trouble.

I was trying install glusterfs on a centos VM (over centos base machine).
For this i needed to install a kernel module called fuse.

I compiled it & installed it. The kernel module file fuse.ko gets created,
but when i try to do "modprobe fuse" I get :
FATAL: Error inserting fuse
(/lib/modules/2.6.18-53.1.19.el5.028stab053.14/kernel/fs/fuse/fuse.ko):
Operation not permitted

There is no permission related issue (i am working as root). The bad thing
is that when i do lsmod on any VM the output is null (I see no kernel
modules at all).  This prompted me on thinking that whether modprobing any
kernel module is allowed or not. ?

Kindly help me sort this problem

Regards
Ritesh

inside container - isn't allowed due to security reasons. You need to load 
fuse.ko on the hardware node.

Hey thanks for the reply. Highly appreciated !
So as you suggested I installed the fuse kernel module on base system. And
could get the glusterfs to install. But even after its installation the
glusterfs was not working. Whenever i tried to mount a remote partition, I
fail, and the logs will say :
2008-05-30 11:00:00 E [xlator.c:120:xlator_set_type] xlator:
dlopen(//lib/glusterfs/1.3.8/xlator/mount/fuse.so): libfuse.so.2: cannot
open shared object file: No such file or directory

i feel this is not a gluster specific problem, and has more to do with
openvz's virtual machines.

Any help ?

I saw similar error during attempt to mount not provided yet filesystem over 
sshfs.

Maybe trying to copy the libs (.so files) from the hardware node into  
the virtual machines? just a guess ...

Point is that the .so file is very much available at refered location. (that
was the main point). Inspite of it being present, all permissions being
available .... it gives error saying, permission denied.
