[Lustre-discuss] Issue regarding lustre client mountpoint

[linux freaker]

Yes, I checked lctl ping command. It is working on lustreclient1 but not on
lustreclient2:

LustreClient1:

 lctl list_nids
192.168.1.4 at o2ib


 lctl ping 192.168.1.1 at o2ib0
12345-0 at lo
12345-192.168.1.1 at o2ib


LustreClient2:

lctl network up
LNET configured

lctl ping 192.168.1.1 at o2ib0
failed to ping 192.168.1.1 at o2ib: Input/output error
