[lustre-discuss] luster client mount issues

Sun Jul 17 01:19:18 PDT 2016

Hi,

try 'lctl ping' from your clients to the MDS to check if you get through on lnet, e.g.

lctl ping ping 192.168.200.52 at o2ib

or

lctl ping 192.168.111.52 at tcp

and vice versa from the MDS to the clients' nids.

Regards,
Thomas
