Dante,

   Your old debian is running OCFS 1.4 and your new Centos is running OCFS
1.2, right?

   If you are running Centos 5.0 you should be able to install OCFS 1.4. 

   If not you will need to umount your debian before mounting the Centos.
Beware that there are functionalities on OCFS 1.4 that are not available on
1.2, that might impact your applications.

   Also I am not sure if the disk layout is fully compatible if certain OCFS
1.4 filesystem options were enabled on your old cluster. The best option
would be to upgrade to OCFS 1.4 on the Centos cluster.

Regards,
Luis

Thanks Tao, I've setup the same on both nodes and the cluster becomes
online.
Now, when I try to mount the following errors appears on node 1 (new
CentOS):
(2512,1):o2net_connect_expired:1585 ERROR: no connection established with
node 0 after 30.0 seconds, giving up and returning errors.
(3022,1):dlm_request_join:901 ERROR: status = -107
(3022,1):dlm_try_to_join_domain:1049 ERROR: status = -107
(3022,1):dlm_join_domain:1321 ERROR: status = -107
(3022,1):dlm_register_domain:1514 ERROR: status = -107
(3022,1):ocfs2_dlm_init:2024 ERROR: status = -107
(3022,1):ocfs2_mount_volume:1133 ERROR: status = -107
ocfs2: Unmounting device (147,0) on (node 1)

And the following

 on node 0 (old Debian)

 (2228,0):o2net_check_handshake:1093 node nodo2 (num 1) at
192.168.168.2:7777 advertised net protocol version 103 but 2 is required,
disconnecting

I believe the Debian message is clear, protocol version incompatibility.

Are there a way to resolve it?

Thanks

Dante

Node1 start connection with node0, so you see the messages related to node0
on node1. It looks like your configuration in

 node1 is wrong.
Please make sure that value of O2CB_HEARTBEAT_THRESHOLD in
/etc/sysconfig/o2cb of node1 is the same as that in node0.

Tao
