 ===== Note =====
 Ubuntu server 10.04.1 installer has a known bug that prevents new installation on software RAID system from booting correctly (see [[http://ubuntuforums.org/showthread.php?t=1474950]] for more details). One possible solution to get around this problem is to setup disk partition and software RAID using 9.10 installation CD before installing 10.04.
+===== Sample partition =====
+  * HD: 500Gb * 3 (RAID 1, 1 hot spare)
+    * /dev/md0: /boot, 200Mb, primary, ext2
+    * /dev/md1: swap, 8G, primary
+    * /dev/md2: /, 200Gb, primary, ext4
+    * /dev/md3: /var, 150Gb, logical, ext4
+    * /dev/md4: /home, 100Gb, logical, ext4
+    * /dev/md5: /tmp, max, logical, ext4
