Hello all, Here is the script i use to create the config.xml file -------------------------------------------------------------------------- #!/bin/sh # Create nodes lmc -o config.xml --add net --node n001 --nid n001 --nettype tcp lmc -m config.xml --add net --node n002 --nid n002 --nettype tcp lmc -m config.xml --add net --node n003 --nid n003 --nettype tcp lmc -m config.xml --add net --node n004 --nid n004 --nettype tcp lmc -m config.xml --add net --node client --nid ''*'' --nettype tcp # Cofigure MDS lmc -m config.xml --add mds --node n001 --mds mds1 --fstype ext3 --dev /tmp/mds --size 900000 # Configures OSTs lmc -m config.xml --add lov --lov lov --mds mds1 --stripe_sz 1048576 --stripe_cnt 0 --stripe_pattern 0 lmc -m config.xml --add ost --node n002 --lov lov --ost ost1 --fstype ext3 --dev /tmp/ost1 --size 900000 lmc -m config.xml --add ost --node n003 --lov lov --ost ost2 --fstype ext3 --dev /tmp/ost2 --size 900000 lmc -m config.xml --add ost --node n004 --lov lov --ost ost3 --fstype ext3 --dev /tmp/ost3 --size 900000 # Configure client (this is a ''generic'' client used for all client mounts) lmc -m config.xml --add mtpt --node client --path /mnt/lustre --mds mds1 --lov lov ------------------------------------------------------------------------------- I then successfully started the OST s and then the MDS. The issue occurs when I try to mount lustre on the clients. I issue the following command on the clients: mount -t lustre n001:/mds/client /mnt/lustre The following error occurs: /sbin/mount.lustre: No such device Please let me know what I am doing wrong... Thank you !!
