Hi All.
I'm trying to configure lustre CFS on 2 servers (1 MDS, 1 OST - both
SUSE enterprise 10).
Everything seems to be fine, it's startup and I could see /mnt/lustre
mounted properly. However when I try to copy file after few seconds it
says "No space left on device", even so there is a bunch of free space.

Here is what I have on those servers:
foma - MDS, susen - OST

Here is my config:
#!/bin/sh

# config.sh
# SuSen - MDS,OTS1 and client1
# Foma - OTS2 and client2

# Create nodes
rm -f config.xml
lmc -m config.xml --add node --node susen
lmc -m config.xml --add net --node susen --nid susen --nettype tcp
lmc -m config.xml --add node --node foma
lmc -m config.xml --add net --node foma --nid foma --nettype tcp
#lmc -m config.xml --add net --node client --nid '*' --nettype tcp

# Cofigure MDS
lmc -m config.xml --add mds --node foma --mds mds-test --fstype ext3
--dev /tmp/mds-test --size 50000

# Configures OSTs
lmc -m config.xml --add lov --lov lov-test --mds mds-test --stripe_sz
1048576 --stripe_cnt 0 --stripe_pattern 0
lmc -m config.xml --add ost --node susen --lov lov-test --ost ost1-test
--fstype ext3 --dev /tmp/ost1-test --size 100000
lmc -m config.xml --add ost --node susen --lov lov-test --ost ost2-test
--fstype ext3 --dev /tmp/ost2-test --size 100000
lmc -m config.xml --add ost --node susen --lov lov-test --ost ost3-test
--fstype ext3 --dev /tmp/ost3-test --size 100000

# Configure client (this is a 'generic' client used for all client
mounts)
lmc -m config.xml --add mtpt --node foma --path /mnt/lustre --mds
mds-test --lov lov-test



Any suggestion ?
