I have a Sun J4400 SAS1 disk array with 24 x 1T drives in it connected

I used 'arcconf' to create a big RAID60 out of (see below).
But then I mount it and it is way too small :
[root@solexa1 StorMan]# df -h /dev/sdb1
Filesystem Size Used Avail Use% Mounted on
/dev/sdb1 186G 60M 176G 1% /mnt/J4400-1
Here is how I created it :
*snip*
And then make an ext4 filesystem on that :
sfdisk's man page says "sfdisk doesn't understand the GUID Partition Table
(GPT) format and it is not designed for large partitions. In these cases use
the more advanced GNU parted(8)."
I'd try putting a gpt label on it and then redoing the mkfs
parted --script /dev/sdb mklabel gpt
parted --script /dev/sdb mkpart ext4 2048s -1s
mke4fs /dev/sdb1
Taking the block size * num blocks from the mke4fs output (and converting to
GB) matches up with the 186GB that df is reporting.
Note also that ext4 is limited to 16TB. You'll need to use XFS for a
filesystem larger than that.
