Dear list,
I got this error when I was trying to mount our MDT, which shares the
same partrition with MGS.
[r...@mds01 lustre]# mount -t lustre -L besfs-MDT0000 /lustre/besfs/mdt
mount.lustre: mount /dev/sda1 at /lustre/besfs/mdt failed: Invalid argument
This may have multiple causes.
Are the mount options correct?
Check the syslog for more info.

There is nothing in /proc/fs/MGS /proc/fs/MDT, what can I do ?
