Hi.
Now i'm trying this and it works! for now...
Two nodes: node3 & node4
node4 export his /dev/sdb2 with gnbd_export as "node4_sdb2"
node3 import node4's /dev/sdb2 with gnbd_import (new /dev/gnbd/node4_sdb2)
on node3: gfs_mkfs -p lock_dlm -t node3:node3_gfs -j 4 /dev/gnbd/node4_sdb2
mount -t gfs /dev/gnbd/node4_gfs /users/home
on node4: mount -t gfs /dev/sdb2 /users/home
and both nodes can read an write ths same files on /users/home!!!
Now i'm going for this:
4 nodes on a dedicated 3com 1Gbit ethernet switch:
node2 exporting with gnbd_export /dev/sdb2 as "node2_sdb2"
node3 exporting with gnbd_export /dev/sdb2 as "node3_sdb2"
node4 exporting with gnbd_export /dev/sdb2 as "node4_sdb2"
node1 (main) will import all "nodeX_sdb2" and create a logical volume named
"main_lv" including:
/dev/sdb2 (his own)
/dev/gnbd/node2_sdb2
/dev/gnbd/node3_sdb2
/dev/gnbd/node4_sdb2
Next I will try to export the new big logical volume with "gnbd_export" and
then do gnbd_import on each node.
With that each node will see "main_lv", then mount it on /users/home as gfs
and get a big shared filesystem to work toghether.
Is this the correct way to do the work??? possibly a deadlock???
Sorry if my english isn't very good ;)
