A long time ago I had to install a new ftp server. I chose FreeBSD having in mind past experience with a crash of a squid proxy sever.
After the motherboard of the proxy server crashed, I moved the NIC (Intel based kernel, compiled with “options DEVICE_POLLING”) and the HDD to a new system). I was amazed that no other actions were required…
So, I have installed FreeBSD 5.5-STABLE and setup pure-ftpd. A few days ago I had to do a little bit of work at the hardware and setup a new RAID1 array for two of its disks.
Beacuse it is so simple, I just want point it out here:
Step 1 (“mark the master” disk):
# gmirror label -v -b round-robin gm0 /dev/ad0Metadata value stored on /dev/ad0
Step 2 (force load of gmirror module):
# echo geom_mirror_load="YES" >> /boot/loader.conf (please note the ">>")
Step 3 (modify /etc/fstab):
/dev/ad0s1a becomes /dev/mirror/gm0s1a
Step 4 (reboot):
# reboot
Step 5 (instert the second disk):
# gmirror insert gm0 /dev/ad1
Hit gmirror status to check if it’s ok…
Easy! Isn’t it?

Add extra disks space in freebsd 
buy another pair of 500gb disks
stick them into your server
build a hardware raid1
boot freebsd
mount /dev/ar1s1d on /files/hdd2
edit /etc/fstab
happy users…
Add extra disks space in freebsd (how a bored admin will do it):
buy two big disks for raid1 mirroring
stick them into the fscking old server
boot freebsd
