Yes, exactly, I scheduled a cron job which parse files to rsync them 
with another server. When the script parsed the corrupted files the logs 
said there were I/O error with the SAN.

My problem wasn't on iscsi layer but on the file system layer and a 
e2fsck resolve it properly.

You probably wants to know why I got some errors on the file system in 
my iscsi SAN. It's my fault : before to plug the SAN on the production 
server, it was plugged on the test server. And this test server freezed 
because of a bad memory chip issue (now I have changed the bad chip and 
memtest the new one to prevent future errors) and that happened of 
course during a iscsi session was opened.
When I rebooted the server, I thinked that recovering the journal of 
ext3 file system was sufficient, and it wasn't. Shame on me, I didn't 
tell this fact in the mail before, and I can't explain why I didn't 
realize before that it was the source of this problem. It' so logical.

I don't use multipath for the while, but I will remember.
