[Ocfs2-users] some wield file create issue???

[Alexei_Roudnev]

I had simular behavior, when
- we configured the same iSCSI initiator ID on 2 servers
- so each cluster conncted to the disk for 20 - 30 seconds, then was pulled 
out by second one server;
- and so on... (server 1 -> server 2 -> server 1 -> ...)

Both looked happy (except some IO delays) but they never knew about each 
other on the disk, and so disk changes was visible
on change owner only (and of course  FS was destroyed slowly).
