Filesystem Size Cap

Hi,

I'm running SuSE 10.3-64 Bit, Kernel 2.6.22.16-0.1
It's main purpose is a RAID Server using a Promise RAID Controller.
Everything works fine, I'm able to partition the 6 TB of available space given by the controller. I wanted to make 3 partitions,
1 TB + 1 TB + 4 TB and use ReiserFS or EXT3 (yet not sure about that).
While formatting, it turned out that the 1 TB partitions work well but the 4 TB partition is cut off to 1.6 TB. This holds for both, EXT3 and ReiserFS.
The RAID is set up having 4 KB blocks, as well as both filesystems. If I partition the 4 TB to two 2 TB partitions, I have the full 2 TB available. Next I'll try the LVM to add both of the 2 TB partitions to get the 4 TB one, but this is only my alternative solution.

I thought the 64Bit System should overcome the 32Bit limits. I know the size is limited by 2^32 * Blocksize and sometimes by the kernel. Can someone confirm some limits or give me a hint what to do? :unsure:

The two Commands:
mkfs.reiserfs -b 4096 /dev/sdb3
mkfs.ext3 -b 4096 /dev/sdb3

Btw. autosensing uses 4 KB blocks as well. The command "df . " then reports only 1.6 TB with a block count corresponding to the reported size.

Looking forward,

(un)Lucky

funny: I thought LVM joins x preformatted partitions/devices to a new logical device. Instead it takes x partitions/devices, presenting a new logical device which has to be formatted afterwards. Ok, I didn't thought of this first but seems to be most reasonable - my fault
The new logical volume I get with LVM can be formatted either with EXT3, ReiserFS or XFS without any problems. :blink:

Nevertheless, because I'm able to format the new LVM device having 4TB without problems, I can't see why this shouldn't be possible without using LVM.

Any ideas or comments?
