Issue with Lustre Client setup

MDS:

Code:

#mount
/dev/mapper/vg00-mdt on /mnt/mdt type lustre (rw)

lctl list_nids
192.168.1.1@o2ib

OSS1 and OSS2:

Code:

# lctl list_nids >> Can we run this command on OSS end. No idea?

192.168.1.2@o2ib

 cat /proc/fs/lustre/devices
  0 UP mgc MGC192.168.1.1@o2ib fe161cab-092e-5a7b-0ac1-6081653d099e 5

LustreClient:

Code:

[root@lustreclient1 ~]# mount -t lustre 192.168.1.1@o2ib0:/lustre /mnt/lustre
mount.lustre: mount 192.168.1.1@o2ib0:/lustre at /mnt/lustre 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)

#lctl list_nids
10.94.214.188@tcp
[root@lustreclient1 ~]# ^C
[root@lustreclient1 ~]#

Why client is not mounting

Fixed it through:

lustre_rmmod to unload module and load lustre through modprobe with correct x.x.x.x at o2ib

I am facing issue with another lustreclient:

[root at lustreclient2 ~]# lustre_rmmod
Modules still loaded:

Any idea how to fix it?
