HOWTO: Install FreeBSD 9.0 over software raid 1 mirror using gpart and gmirror

June 3, 2012

Boot FreebSD Installation media , Execute shell on Partitioning menu option.

start with my second hdd, cuz the first is already ready, just repeat .

1. Create GPT partitions on the hard disks first

# gpart create -s gpt ada2

# gpart add -s 700G -t freebsd-ufs -l ada2p1 ada2  /first index will be for the jails/

# gpart add -s 64k -t freebsd-boot -l ada2p2 ada2 /the bootcode partition/

# gpart add -s 200G -t freebsd-ufs -l ada2p3 ada2 /root/

# gpart add -s 400M -t freebsd-ufs -l ada2p4 ada2 /boot/

2. Install bootcodes:

# gpart bootcode -b /boot/pmbr -p /boot/gptboot -i2 ada2 /bootcode on ada2 index 2 – bootcode partition/

# gpart bootcode -b /boot/pmbr -p /boot/gptboot -i2 ada1 /bootcode on ada1 index 2 – bootcode partition/

3. Active and check gpts:

# true > /dev/ada1 && true > /dev/ada2 ; ls /dev/gpt/  <- gpts must be here if everything is ok

4. Active and Create geom mirrir a.k.a. gmirror

# kld_load geom_mirror /load geom mirror module/

#gmirror label jails /dev/gpt/ada1p1 /dev/gpt/ada2p1 /jails partition/

#gmirror label bootcode /dev/gpt/ada1p2 /dev/gpt/ada2p2 /bootcode place/

#gmirror label root /dev/gpt/ada1p3 /dev/gpt/ada2p3 /root partition/

#gmirror label boot /dev/gpt/ada1p3 /dev/ada2p4 /boot partition/

5. Create root filesystem and mount it and config fstab in the way the bsdinstaller expects:

# newfs -U /dev/mirror/root

# mount /dev/mirror/root /mnt

# vi /tmp/bsdisntall_etc/fstab >> /dev/root/mirror / ufs rw 1 1

6. Exit to return back to installer and continue to install the system

# exit

7. Execute shell BEFORE installer end and restart the system!!

Put the geoms in the boot loader.conf 🙂

# echo ‘geom_mirror_load=”YES”‘ >> /boot/loader.conf

#echo ‘daily_status_gmirror_enable=”YES”‘ >> /etc/periodic.conf


That’s it
