[Centos] What's the biggest software raid partition?

[chawming at pacific.net.sg (Ho Chaw Ming)]

Hi

I just installed CentOS 3.3 (Will try 4 later). I have 10 x 250GB harddisk
which I build in a Raid-5 Config. 

/proc/mdstat:
Personalities : [raid5]
read_ahead 1024 sectors
Event: 2
md0 : active raid5 hdl1[9] hdk1[8] hdj1[7] hdi1[6] hdh1[5] hdg1[4] hdf1[3]
hde1[2] hdd1[1] hdb1[0]
      -2088962752 blocks level 5, 64k chunk, algorithm 0 [10/10]
[UUUUUUUUUU]
      [>....................]  resync =  2.8% (6954048/245111616)
finish=387.2min speed=10249K/sec
unused devices: <none>


/etc/raidtab:

/dev/md0              57601604     32828  54642732   1% /volume1


/dev/md0 shows as 50GB when I did a df. 

Is there a size limitation to the biggest software raid on a default kernel
installation? 

Thanks in advance. 

Regards.
