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!! Fábio
