Using the rest of my hard drive

UNIX Solaris

Hi

When I installed opensolaris, I installed it on a 20GB partition. How do I make use of the other 300GB I have spare?

format shows:-

-bash-3.2# format

Your slice2 (whole disk space) shows only 20G from the partition table.
Did you do a clone or at least did you assigned the remaining size to any unused partition during install ? I'm not sure if you can expand beyond this now, and afraid that you might loose your data if you try purging the disk to get back its original volume of 300G

you can use "fdisk" to make use of the rest of your harddrive... add a new partition to use for solaris. don't try to grow your existing partition!

Thanks DukeNuke2

             Total disk size is 38913 cylinders
             Cylinder size is 16065 (512 byte) blocks

i just installed a bunch of x4200m2 servers from sun with solarisx86 and i've to use fdisk alot ;).

Ouch.
You can't have more than one Solaris/Solaris2 partition. It might make your system unbootable.

Set partition 2 type to something else and create a ZFS pool on it if you are running Solaris 10. If you aren't, you can create a ufs partition on c3d0p2 but that's not straightforward.

Edit: just noticed your root partition is on ZFS, so you are definitely using Solaris 10u6 or Solaris Express, so just create a ZFS pool and you are set.

Ok, I've changed it to 'UNIX System' how would I make a zfs pool named 'minisan'?

8

read the manpage of "zpool".

# zpool create yourpool dev
9

zpool create yourpool /dev/dsk/c3d0p2 ??

10

cool, it all works :slight_smile:

11

it's easy, isn't it? :wink:

12

indeed, I was expecting it to be harder, I've already installed VirtualBox, and installed XP Pro in 11 minutes!

zfs is a beautiful thing!! they really got the initial setup of this fs right. super easy.
