Thanks Rick, 1) Run "debugfs -c $MGT_DEVICE" on the MGS server, and then cd into the CONFIGS/ directory to check if the "client1-client" config file exists.
[root@mgs]# debugfs -c -R 'ls -l CONFIGS' /dev/mapper/mpathcp1 debugfs 1.42.12.wc1 (15-Sep-2014) /dev/mapper/mpathcp1: catastrophic mode - not reading inode or group bitmaps 32769 40755 (2) 0 0 4096 6-Jan-2015 13:09 . 2 40755 (2) 0 0 4096 6-Jan-2015 13:10 .. 12 100644 (1) 0 0 12288 6-Jan-2015 13:10 mountdata 81 100644 (1) 0 0 0 6-Jan-2015 13:10 params-client 82 100644 (1) 0 0 0 6-Jan-2015 13:10 params 83 100644 (1) 0 0 11200 6-Jan-2015 13:10 temp-client 84 100644 (1) 0 0 9792 6-Jan-2015 13:10 temp-MDT0000 104 100644 (1) 0 0 10600 6-Jan-2015 13:12 client2-client 105 100644 (1) 0 0 8880 6-Jan-2015 13:12 client2-OST0000 107 100644 (1) 0 0 10600 6-Jan-2015 23:38 client1-client 108 100644 (1) 0 0 8880 6-Jan-2015 23:38 client1-OST0000 2) Run a tool like wireshark to monitor the TCP traffic to see if you can determine where the communication is breaking down Is there an RPM package for this ? Let me know if you have that information on top of your head else will look for it. 3) Turn up the Lustre debug level to see if it gives you any more information.
