On the node in question Try: lsmod | grep lustre
followed by: modprobe lustre
I'm betting the modules aren't loaded for some reason, generally that
reason is found in dmesg.

Parag, I have not tested two FS using a common MGT and I don't know
whether it is supported.

Hi Raj,
But I have two file systems,
And I think I can use one mgt for two filesystems. Please correct me
if
I am wrong.

Parag

The following can contribute to this issue:
- Missing FS name in mgt creation (it must be <=9 character long):
--fsname=
mkfs.lustre --servicenode=10.2.1.204@o2ib
--servicenode=10.2.1.205@o2ib --FSNAME=HOME --mgs /dev/mapper/mpathc
- verify if /mdt directory exists

What options in mkfs.lustre did you use to format with lustre?

Hi Raj,
Yes, /dev/mapper/mpatha available.
I could format and mount using ext4.

Parag,
Is the device /dev/mapper/mpatha available?
If not, the multipathd may not have started or the multipath
configuration may not be correct.

Hi,
I am getting below error while mounting mdt. Mgt is mounted.
Please suggest
[root@mds2 ~]# mount -t lustre /dev/mapper/mpatha /mdt
mount.lustre: mount /dev/mapper/mpatha at /mdt failed: No such file
or directory
Is the MGS specification correct?
Is the filesystem name correct?
If upgrading, is the copied client log valid? (see upgrade docs)
Regards,
Parag
