[Gluster-users] "Failed to get IB devices" and "Extended attribute not supported"

[shacky]

Hi.
I'm installing a three nodes GlusterFS cluster on three OpenVZ VPS.
I enabled the FUSE support on the VPSes and I succesfully created a
new volume with replica 3, but I'm still having some problems:

Apr 18 08:50:36 web1 udevd[94]: specified group 'fuse' unknown
Apr 18 08:50:37 web1 GlusterFS[24729]: [2015-04-18 08:50:37.269336] C
[rdma.c:3934:rdma_init] 0-rpc-transport/rdma: Failed to get IB devices
Apr 18 08:57:07 web1 GlusterFS[24950]: [2015-04-18 08:57:07.289529] C
[posix.c:4723:init] 0-data-posix: Extended attribute not supported,
exiting.

The filesystem on the physical node the VPS in running on has extended
attributes:

root at node1:~# tune2fs -l /dev/mapper/system-data
tune2fs 1.42.5 (29-Jul-2012)
Filesystem volume name:   <none>
Last mounted on:          /var/lib/vz
Filesystem UUID:          cb09a3dc-e280-48ab-af96-ca057287fbff
Filesystem magic number:  0xEF53
Filesystem revision #:    1 (dynamic)
Filesystem features:      has_journal ext_attr resize_inode dir_index
filetype needs_recovery extent flex_bg sparse_super large_file
huge_file uninit_bg dir_nlink extra_isize

The volume is not syncing of course.

Could you help me please?

Thank you very much!
