You can't mount ext3 from more than one node (unless all mounts are read-only).  You will immediately corrupt the volume.
 
You have to use a clustered filesystem.  If for some reason you don't want to implement GFS, try another:  http://en.wikipedia.org/wiki/Shared_disk_file_system

Subject: iscsi doubt

Hello,

I have a 2-nodes cluster. I have a shared partition mounted via iscsi. Only one node is active at a time but I see that when I write in one node in the other node I cant see the files created,

ie:

node1
  /dev/sda                972404    107592    815416  12% /iscsivol

node2
/dev/sda                972404    107596    815412  12% /iscsivol

 first the numbers are different and /dev/sda is the same partition. When I create a file with

#touch test
root@node2 iscsivol]# ll
total 24
drwx------ 2 root  root  16384 mar 23 17:25 lost+found
-rw-r--r-- 1 root  root      0 abr 20 10:39 test

in the other node:
[root@node1 iscsivol]# ll
total 24
drwx------ 2 root  root  16384 mar 23 17:25 lost+found

and after a time i get:
[root@node1 iscsivol]# ll
total 24
drwx------ 2 root  root  16384 mar 23 17:25 lost+found
?--------- ? ?     ?         ?            ? test


the filesystem on it is ext3 and I dont want to implement gfs.

Is necessary any special configuration to update de iscsi targets when one client writes to it and with correct info?

Thanks in advance

ESG
