Hey folks,
I have a Sun J4400 SAS1 disk array with 24 x 1T drives in it connected
to a Sunfire x2250 running 5.8 ( 64 bit )
I used 'arcconf' to create a big RAID60 out of (see below).
But then I mount it and it is way too small
This should be about 20TB :
[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 :
./arcconf create 1 logicaldrive name J4400-1-RAID60 max 60 0 0 0 1 0 2
0 3 0 4 0 5 0 6 0 7 0 8 0 9 0 10 0 11 0 12 0 13 0 14 0 15 0 16 0 17 0
18 0 19 0 20 0 21 0 22 0 23 noprompt
[root@solexa1 StorMan]# ./arcconf getconfig 1 ld
Controllers found: 1

Make 1 big partition :
sfdisk /dev/sdb <<EOF
,,L
EOF
[root@solexa1 StorMan]# sfdisk -l /dev/sdb
Disk /dev/sdb: 2430685 cylinders, 255 heads, 63 sectors/track
Units = cylinders of 8225280 bytes, blocks of 1024 bytes, counting from 0
Device Boot Start End #cyls #blocks Id System

/dev/sdb2 0 - 0 0 0 Empty
/dev/sdb3 0 - 0 0 0 Empty
/dev/sdb4 0 - 0 0 0 Empty
And then make an ext4 filesystem on that :
[root@solexa1 StorMan]# mke4fs /dev/sdb1

This filesystem will be automatically checked every 30 mounts or
180 days, whichever comes first. Use tune4fs -c or -i to override.
