[Lustre-discuss] getting "Not a directory" when accessing mount point

I'm running lustre 1.8.1.1 on CentOS 5.4.

 

I ran the following:

mkfs.lustre --mgs --mdt /dev/hdb

mount -t lustre /dev/hdb /mnt/lustre

 

And everything worked without errors and I got the following messages in
my logs:

Nov 25 11:23:58 localhost kernel: Lustre: lustre-MDT0000: new disk,
initializing

Nov 25 11:23:58 localhost kernel: Lustre: MDT lustre-MDT0000 now serving
lustre-

MDT0000_UUID (lustre-MDT0000/58b19442-2b9c-b7b6-4afc-c75a269effbc) with
recovery enabled

Nov 25 11:23:58 localhost kernel: Lustre:
2792:0:(lproc_mds.c:271:lprocfs_wr_group_upcall()) lustre-MDT0000: group
upcall set to /usr/sbin/l_getgroups

Nov 25 11:23:58 localhost kernel: Lustre: lustre-MDT0000.mdt: set
parameter group_upcall=/usr/sbin/l_getgroups

Nov 25 11:23:58 localhost kernel: Lustre: Server lustre-MDT0000 on
device /dev/hdb has started

 

And "df -h" shows the correct size of my lustre filesystem. However, if
I try to ls (or access in other ways) to /mnt/lustre I get:

 

ls: /mnt/lustre: Not a directory

 

I was under the impression I didn't need to create OSTs.  Any ideas what
I'm doing wrong?  How do I access the lustre storage?
