My scheme is: |
2 |
100 M /boot on ext3 (I was going to store some other info there, but |
3 |
its mostly "space" att) |
4 |
|
5 |
2G swap |
6 |
|
7 |
4G reiserfs with a complete, basic gentoo rescue install - if all goes |
8 |
pear shaped, I have a backup including a functioning /boot on this |
9 |
partition. Particularly useful with things like a gateway: you can come |
10 |
up on the rescue partition and provide near normal service/network |
11 |
access while fixing the main problem in a chroot etc. Maintenance of |
12 |
this partition is done offline in a chroot so other than an occasional |
13 |
test, its rarely run in its own right. |
14 |
|
15 |
4G / on reiserfs with /etc, /root etc |
16 |
|
17 |
remainder (200G is below, and on my main desktop system similarly |
18 |
arranged I have 200G + an extra 60G drive) is all LVM |
19 |
containing /home, /var, /tmp and /usr. |
20 |
|
21 |
This system is mainly a LAMP server/gateway for a home network. it also |
22 |
contains mostly file storage and backups in /home |

There are probably performance issues, but they are not noticeable in |
40 |
practise. hdparm actually shows a slight speed advantage for the LVM |
41 |
partitions, but there are also error messages so I dont really trust it! |
