brezhnev# ls /dev/ad*
/dev/ad0 /dev/ad0s1a /dev/ad0s1c /dev/ad0s1e /dev/ad1s1 /dev/ad3s1
/dev/ad0s1 /dev/ad0s1b /dev/ad0s1d /dev/ad1 /dev/ad3
and then using mount to show what's already in use:
brezhnev# mount
/dev/ad0s1a on / (ufs, local)
devfs on /dev (devfs, local)
/dev/ad0s1e on /home (ufs, local, soft-updates)
/dev/ad0s1d on /usr (ufs, local, soft-updates)
So ad0 is take up with the base OS installation, which means that ad1 and ad3 must be the other two spare drives. One of them is a 60GB stack of empty platters (mmm) and the other is 40GB of CVS and project goodness (as yet unmounted).
Just running mount as you might on a linux system isn't too friendly with ext2. Here's what happens:
brezhnev# mkdir opt
brezhnev# mount /dev/ad3s1 /opt
mount: /dev/ad3s1 on /opt: incorrect super block
even if you specify the fs type, things aren't exactly pretty. The reason for this is that freeBSD comes with a suite of varients of the mount command designed for the different filesystems in question. So here's how to mount that big 60G device into /opt in a freeBSD stylie:
brezhnev# /sbin/mount_ext2fs /dev/ad3s1 /opt
Now, to make this persist and survive a reboot all we need to do is add entries to /etc/fstab. Here's what mine looks like after I have added these two new drives:
brezhnev# cat /etc/fstab
# Device Mountpoint FStype Options Dump Pass#
/dev/ad0s1b none swap sw 0 0
/dev/ad0s1a / ufs rw 1 1
/dev/ad0s1e /home ufs rw 2 2
/dev/ad0s1d /usr ufs rw 2 2
/dev/acd0 /cdrom cd9660 ro,noauto 0 0
/dev/ad1s1 /share ext2fs rw 1 1
/dev/ad3s1 /opt ext2fs rw 1 1
so now we just need to reboot and this is what we see in the console with df -h:
brezhnev# df -h
Filesystem Size Used Avail Capacity Mounted on
/dev/ad0s1a 2.3G 71M 2.1G 3% /
devfs 1.0K 1.0K 0B 100% /dev
/dev/ad0s1e 32G 42K 29G 0% /home
/dev/ad0s1d 2.3G 1.9G 202M 91% /usr
/dev/ad1s1 38G 34G 1.8G 95% /share
/dev/ad3s1 56G 4.0K 54G 0% /opt
Looks great - altho I'm not sure wny 4GB are reported as used. Might be a good time to try fdisk on that device, switch it over to ufs (freeBSD's native filesystem) and retreive that space...
