I am having some trouble getting 4 x 2TB sata disks into one big single
softraid (raid 5) disk. I can create the softraid0 disk and it's 5.5TB
want would like to get a single 5.5TB partition but can only make one
single 1.5TB partition! Can someone tell me where I'm going wrong.
Thanks
Keith
===================
Start from fresh and delete softraid0 disk...
#bioctl -d sd0
## Wipe the first part of the disks.
#dd if=/dev/zero of=/dev/rwd0c bs=10m count=1
#dd if=/dev/zero of=/dev/rwd1c bs=10m count=1
#dd if=/dev/zero of=/dev/rwd2c bs=10m count=1
#dd if=/dev/zero of=/dev/rwd3c bs=10m count=1
#fdisk -iy wd0
#fdisk -iy wd1
#fdisk -iy wd2
#fdisk -iy wd3
## Make a partition of type RAID
#printf "a\n\n\n\nRAID\nw\nq\n\n" | disklabel -E wd0
#printf "a\n\n\n\nRAID\nw\nq\n\n" | disklabel -E wd1
#printf "a\n\n\n\nRAID\nw\nq\n\n" | disklabel -E wd2
#printf "a\n\n\n\nRAID\nw\nq\n\n" | disklabel -E wd3
#bioctl -c 5 -l /dev/wd0a,/dev/wd1a,/dev/wd2a,/dev/wd3a softraid0

#dd if=/dev/zero of=/dev/rsd1c bs=1m count=1
#fdisk -iy sd1
This give me....
# fdisk -e sd1
