[lustre-discuss] MDS Config Help: Are the lustre modules loaded?

[Sangeetha Banavathi Srinivasa]

Hi,

Below are the steps I executed in configuring MDS.

1. mkfs.lustre --fsname lustre --mdt --mgs /dev/vg00/mdt
2. mkdir /mdt

3. mount -t lustre /dev/vg00/mdt /mdt

I see the below error after step 3:

mount.lustre: mount /dev/mapper/vg00-mdt1 at /mdt failed: No such device
Are the lustre modules loaded?
Check /etc/modprobe.conf and /proc/filesystems
[root at amaranth3 lustre]# 


I tried modprobe lustre and retried mounting but it resulted in the same error.  Any help will be appreciated.
