Hi again..

mail flood today :)


Extremely simple setup, 3 nodes cluster, no services or anything fancy. One
shared block device (aoe + vblade) on 2.6.24-rc1.

node1# mkfs.gfs -j 6 -p lock_dlm -t gutsy:gfs /dev/etherd/e0.0

mount -t gfs /dev/etherd/e0.0 /mnt/gfs

/dev/etherd/e0.0      256M   20K  256M   1% /mnt/gfs

the device is a 1GB exported disk.

root at node1:~# cat /proc/partitions
major minor  #blocks  name

   8     0    1048576 sda
   8     1     931738 sda1
   8     2          1 sda2
   8     5     112423 sda5
 152     0    1048576 etherd/e0.0

Cheers
Fabio

Default journal size is 128M so 128M x 6 = 768M, leaving only 256M for
the data.
