what is the max size of a disk for 32bit arch?

russianwizard · 2009-06-05 16:27:02

I'm looking to add alot of hard disk space to my dell poweredge 2450 server. Since it has dual pentium 3's 64bit arch is out of the question. I've heard that 32bit windows XP can only have disks up to 2tb in size. Does this apply to arch 32bit as well?

I think it depends on the filesystem you pick?

Googling gives me this as second (!) hit:

In the latest version of arch, would LFS be enabled by default?

Are you running Arch on it already? If not, why dont you check? Kernel configuration is in /boot and probably in /proc/config.gz too.

Edit: your sig says you are... Show some initiative .

The limit is marked by the filesystem.

here:
http://en.wikipedia.org/wiki/Comparison_of_file_systems

fs supported by linux and maximum file/partition size:
xfs supports 8EB/8EB
ext4 supports 16TB/1EB
jfs supports 4PB/32PB

that is more, much more that you need

Not sure where you heard this about XP (unless XP on FAT32)
NTFS 16EB/16EB
There is a catch here though: windows XP partitioner is only 32 bit so to format extremerly large partitions for NTFS, you need third party formatter.

Wikipedia contains lots of info, too.

The maximum volume size of for instance ext3 depends on what blocksize you chose for that filesystem; with blocksize 8 KiB, you can create partitions of up to 16 TiB.

In case you need to store extreme amounts of data, or perhaps you just want the scalability, it's worth noting that Wikipedia claims ext4 can support a partition of size 1 EiB (=1024*1024 TiB), and XFS supports volume sizes of 8 EiB (and can actually fill that whole partition with only one file, if desired.)

Thanks good to know. I'm prob gonna raid 3 1.5tb disks in raid 5 to get 3tb of storage

Lol.... I have a 3x 1 TB RAID 5 here in my server - frankly I never thought for a minute that would give a problem. You can call that rash, but I don't think it is - while it may be 'big' even for today's desktop standards, it's nothing uncommon in servers, and that's an area where Linux traditionally shines. So nothing to worry about I'd say. You'd have to drop in a lot of big HDs to get to that critical point (eight 2 TB HDs anyone?).
