Hi,

Using v1.0.4, pre-patched kernel, RH8.0.
 I've successfully configured the 0-config setup with 1 filesystem, but
cannot get a file system to mount when 2 or more file systems are
configured.
Are 2 or more file systems possible with 0-config or is there something
wrong with the following configuration?

The setup is:

node0 has 2 mds devices, 1 for each file system.
node10 has 2 ost's (1 ost per  file system)
node2 is the client

The error when attempting to mount the first file system is:

[root@node2 lustre]# mount -t lustre -o nettype=tcp node0:/mds1/client
/mnt/lustre1
/sbin/mount.lustre: Invalid argument

and the errors in /var/log/messages on node2:

'lwizard' was used to create config.xml and config.sh.
lconf on node10 (ost server) and node0 (mds server) runs without errors.

config.sh created from lwizard looks like:

[root@node0 lustre]# cat config.sh
--add node --node node0
--add net --node node0 --nid node0 --nettype tcp
--add mds --node node0 --mds mds1 --fstype ext3 --dev /tmp/mds1 --size
100000
--add lov --lov lov1 --mds mds1 --stripe_sz 1048576 --stripe_cnt 1
--stripe_pattern 0
--add node --node node10
--add net --node node10 --nid node10 --nettype tcp
--add ost --node node10 --lov lov1 --fstype ext3 --dev /scratch/ost1 --size
100000
--add node --node client
--add net --node client --nid client --nettype tcp
--add mtpt --node client --mds mds1 --lov lov1 --path /mnt/lustre1
--add mds --node node0 --mds mds2 --fstype ext3 --dev /tmp/mds2 --size

--add lov --lov lov2 --mds mds2 --stripe_sz 1048576 --stripe_cnt 1

--add ost --node node10 --lov lov2 --fstype ext3 --dev /scratch/ost2 --size

--add mtpt --node client --mds mds2 --lov lov2 --path /mnt/lustre2
