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
  1 UP ost OSS OSS_uuid 3
  2 UP obdfilter lustre-OST0006 lustre-OST0006_UUID 5
  3 UP obdfilter lustre-OST0007 lustre-OST0007_UUID 5
  4 UP obdfilter lustre-OST0008 lustre-OST0008_UUID 5
  5 UP obdfilter lustre-OST0009 lustre-OST0009_UUID 5
  6 UP obdfilter lustre-OST000a lustre-OST000a_UUID 5
  7 UP obdfilter lustre-OST000b lustre-OST000b_UUID 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:
lnet/klnds/socklnd/ksocklnd.o lnet/lnet/lnet.o libcfs/libcfs/libcfs.o
[root at lustreclient2 ~]#
[root at lustreclient2 ~]# modprobe lustre
[root at lustreclient2 ~]# modprobe lnet
[root at lustreclient2 ~]# ping 192.168.1.1
PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data.
64 bytes from 192.168.1.1: icmp_seq=1 ttl=64 time=0.233 ms
^C
--- 192.168.1.1 ping statistics ---

rtt min/avg/max/mdev = 0.233/0.233/0.233/0.000 ms
[root at lustreclient2 ~]# mount -t lustre 192.168.1.1 at o2ib0:/lustre
/mnt/lustre
mount.lustre: mount 192.168.1.1 at 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)
[root at lustreclient2 ~]# ^C
[root at lustreclient2 ~]#


Any idea how to fix it?
