Konstantin,

A quick thought: Did you deliberately remove your file system name and replace it with <fsname> in your email?  Otherwise, you probably want to change the file system name in the format command and try again.  I’ think the ‘<‘ and ‘>’ symbols may cause problems.  (If not now, they probably will for some other software at some point.)

Subject: [HPDD-discuss] Can't Mount MDT on MDS/MGS server

Hello, I am new to Lustre and am trying to setup a simple environment (1 of each Client, MDS, OSS) to test basic functionality and to familiarize myself with the installation procedures.

I currently have 3 VM’s each running CentOS 6.5. I have 3 nic in each box, with eth0 being used for ssh and eth1 and 2 being teamed under bond0. I want all LNET communication going through the bond0 interface.

My lustre.conf:

# cat /etc/modprobe.d/lustre.conf)

options lnet networks=tcp0(bond0)

 

I have disabled iptables, selinux, etc. I can load and start lnet. I can ping each machine’s bonded interface using normal ping  so I know the networking is fine. Right now the MDS is the only server on.

 

# lctl ping 100.100.100.10@tcp0

12345-0@lo

12345-100.100.100.10@tcp

 

When I try to mount the MDT, I get this error:

# mount –t lustre /dev/sdb /mnt/mdt

LustreError: 11-0: <fsname>-MDT0000-lwp-MDT0000: Communicating with 0@lo, operation mds_connect failed with -11

 

Any help would be appreciated.

 

Thank You,

-Konstantin
