Large Filesystem (about 24TB)

Hi,

I want to create a filesystem on a 24 TB partition, but I can't.
So what filesystem should I use, and how should I create and mount it?

I'm using Centos 5.5 on a x86 Machine, partition table is GPT, created with parted.

I tried the following:

1. Create the praised ext4 filesystem:

Code:

# mkfs.ext4 /dev/sde3

mke4fs 1.41.9 (22-Aug-2009)

mkfs.ext4: Size of device /dev/sde3 too big to be expressed in 32 bits

        using a blocksize of 4096.

--> failed
Then I forced a block size of 8192 .. worked but mounting crashed the machine.
AFAIK, the mkfs does not support > 16 TB.

2. Create xfs which should handle it:

Code:

# mkfs.xfs /dev/sde3

meta-data=/dev/sde3              isize=256    agcount=32, agsize=175303405 blks

        =                      sectsz=512  attr=0

data    =                      bsize=4096  blocks=5609708960, imaxpct=25

        =                      sunit=0      swidth=0 blks, unwritten=1

naming  =version 2              bsize=4096  

log      =internal log          bsize=4096  blocks=32768, version=1

        =                      sectsz=512  sunit=0 blks, lazy-count=0

realtime =none                  extsz=4096  blocks=0, rtextents=0



# mount /dev/sde3 /data

mount: Argument list too long

Any ideas?

PS: I don't care about what filesystem to use, but it should support quota.

Searching Google for argument too long shows quite a few hits. Evidently you are hitting a limitation of x86 architecture. Switching to _64 (if possible) and using XFS should work for you.

Also have a look at jfs.

xfs is not capable of >16TB without a 64bit system and like you have found out the ext utilities can not support >16TB yet.

D'oh, you're right :study:

Thanks a lot ... I'll go and buy a x86_64-Bit system now and get xfs running. :)
