Hi,

The iSCSI RAID we have is about 26TB netto and I'm again faced with the question: How many partitions, which filesystem, which mount options etc.

My favourite for now is 3 to 4 filesystems with the default ext4 settings. (Redhat EL 5.7, may be soon 6.1)

You should seriously consider XFS (supported natively in RHEL and hence Centos 6) for any single filesystem >16TB. (EXT4 supports only upto 16TB)

BTW 2 . I thought, the max. filesystemsize is 1EB and not 16TB.

The max FILEsize should be 16TB ...
