[Xen-users] ERROR: -91 after Kernel Upgrade

[Mike Fröhner <mikefroehner@xxxxxx>]

Hey guys,

I have a OCFS2 Cluster mounted at 4 xen-server (gentoo). Today I 
upgraded the xen-kernel for tests at one server (server2) from 
2.6.34-xen to 2.6.38-xen-r1. After reboot the server couldn't mount the 
ocsfs2 device anymore.
ocfs2-tools version: sys-fs/ocfs2-tools-1.4.3

Modules are loaded and /config type configfs and /dlm type ocfs2_dlmfs 
are mounted.
server2 ~ # mount /data/
mount.ocfs2: Protocol not available while mounting /dev/sdb1 on /data. 
Check 'dmesg' for more information on this error.
server2 ~ # dmesg

Does anybody know this problem? Is this error caused by different kernel 
/ module versions?

Regards,
Mike
