File Server and Raid

[ruscook]

It's fairly  simple now, I did it in the graphical installer. Here's my
partitions including using LVM on a s/w mirror for /home.

Filesystem Type   1M-blocks Used Available Use% Mounted on
/dev/md0       xfs       9529M     4899M     4630M  52% /
/dev/md1      ext3        177M       32M      136M  19% /boot
/dev/mapper/home-home
               xfs     282060M   230613M    51448M  82% /home
/dev/md4       xfs       9505M        1M     9505M   1% /tmp

The only "trick" I can remember was during install:
1) ensure both HDDs were physically the same
2) partition EACH exactly the same (1 & 2 are the key to this)
3) go to the raid config section of the install, match each partition on hda with its corresponding one on hdb and make them a raid set.
4) make file systems and mount points of the newly created raid sets as necessary.
5) I did this for swap and tmp just to use the space equally on the 2 disks and ensure I could boot 100% if one failed.
6) leave partition section of installer and carry on.

As you can see I can use XFS in a raid set as root because /boot is on its own ext3 partition for use of grub in booting.

I think that was it - I did it a month ago so may have forgotten something.
