Could you please include output from dmesg or /var/log/messages from
MDS startup.

Hello,
 
I installed lustre 1.4.3 and it consist of one MDS, two OSTs.
 
Configuration likes below.
 --add net --node mds --nid mds --nettype tcp
 --add net --node ost1 --nid ost1 --nettype tcp
 --add net --node ost2 --nid ost2 --nettype tcp
 --add net --node client --nid * --nettype tcp
 
 --add mds --node mds --mds mds1 --fstype ldiskfs --dev /dev/hda5
 
 --add lov --lov lov1 --mds mds1 --stripe_sz 262144 --stripe_cnt 1
--stripe_pattern 0
 
 --add ost --node ost1 --lov lov1 --ost ost1 --fstype ldiskfs --dev
/dev/hda2
 --add ost --node ost2 --lov lov1 --ost ost2 --fstype ldiskfs --dev
/dev/hda2
 
 --add mtpt --node client --path /mnt/lustre --mds mds1 --lov lov1
 

OSTs started well. but, MDS had a message like below and then suspended
processing.
