Backup in iSCSI - FS corruption

["Fábio R. Medeiros"]

Hello,

I'm creating a backup solution with Bacula running on FreeBSD10. The 
storage device is an iSCSI NAS (it's one made by Enhance Inc.) running 
RAID-5.

The array of disks are using UFS2+J. Now I know this was a bad choice... 
I've got issues with FS corruption probably due concurrency and 
different OS managing the iSCSI target.

I've searched about clustered file systems but I haven't any experience 
on them. I don't know if these FS could solve the issues addressed above.

And a concern is that FreeBSD ported just some of these clustered FS 
(probably I'll use MooseFS). Well, are they stable? Work fine with iSCSI 
devices?

Best regards!!
