Hello,

Finally the DRBD is running, I made the tests :

@server01#mount -t ext3 /dev/drbd0 /mnt
@server01#cd /mnt/ ; echo running > newfile
@server01#cd / ; umount /dev/drbd0
@server01#drbdadm secondary all
@server02#drbdadm primary all
@server02#mount -t ext3 /dev/drbd0 /mnt
@server02#ls /mnt
@server02#cat /mnt/newfile

Then the file crated in server01 go to server02, but when I try cat /proc/drbd in two servers :

root at server1:~# cat /proc/drbd
version: 8.2.5 (api:88/proto:86-88)

I saech about Inconsistent in http://www.linux-ha.org/DRBD/FAQ, but I don't understanded.

It can to bring problems ?

Other doubts: 
* I must the put the line in /etc/fstab of /dev/drb0 in my primary server ?

* I read that drbd cant be begin when the machine is reset.
  Why it's happen ?

* How I can to start drbd ? 

Best regards

Faria


ps : I think thso is not done manually
