 |
|
i have a fair number of installations under the belt. initially i followed a particular partitioning scheme, but now i been trying to change up.
how do you guys typically partition a drive? 20G, 40G, 60G, 100G, 250G?
curious on what everyon else does |

My 160 GiB so only about 150 GB
10 for /
30 for /usr
105 for /home
4 for swap
64 megs for /boot
I don't run a webserver or anything, so I didn't make /var a separate partition.

gohmdoree,
Thats what I have.
| Code: | $ df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/md/1 9629624 1700288 7440172 19% /
/dev/md/2 57685372 45850924 8904204 84% /usr
/dev/md/3 3857992 977608 2684404 27% /usr/local
/dev/md/4 11543192 1197312 9759520 11% /tmp
/dev/md/5 30771648 16010400 13198140 55% /var
/dev/md/6 461357848 281486876 156435364 65% /home
none 518072 0 518072 0% /dev/shm
/dev/md/0 38792 18683 18106 51% /boot |
In addition, swap is two equal priority 1Gb partitons

I typically use separate partitions for: | Code: | /boot
/
/tmp
/usr
/usr/portage
/usr/local
/var
/var/log
/home
/opt
swap |
And with more than one drive I place the swap partition as the first primary on one of the them.
An important consideration, especially for servers, that I discovered the hard way is to always have a separate /var/log partition. One of the earlier servers I set up many moons ago as a 'nix noob was a SuSE 7.3 system where I accepted the default partitioning scheme (maybe 3 partitions if you're lucky) ran fine for years but then one day decided to have a problem. The problem was not that bad and easily solvable but the system basically crashed/halted, not directly because of the problem, but indirectly because of the constant error logging causing all of the hard drive space to fill. If there had been a separate /var/log partition the customer would not have been impacted so.
With Gentoo I use that separate /usr/portage partition to avoid accidently filling up /usr with downloaded 'distfiles'.

I have an 18Gb drive like so: | Code: | Filesystem Size Used Avail Use% Mounted on
/dev/sda2 84M 14M 66M 17% /boot
/dev/sda3 297M 177M 90M 67% /
/dev/sda5 8.0G 4.6G 3.5G 57% /usr
/dev/sda7 2.0G 7.8M 2.0G 1% /tmp
/dev/sda8 2.0G 1.4G 702M 66% /opt
/dev/sda9 4.0G 2.7G 1.4G 66% /home/portage |
sda1 is a Dell utility partition, sda6 is swap (~512M) and is near the seek-center of the disk (which hardly matters as the system rarely swaps nowadays). I have my own peculiar reasons for sda9 being what it is, but effectively it's /usr/portage/distfiles.
/usr is mounted read-only. I'd do the same with /opt but some apps installed there expect to be on a writable filesystem  .
My second drive (73GB) is simpler: | Code: | /dev/sdb1 50G 39G 12G 78% /home
/dev/sdb4 6.0G 903M 5.1G 15% /var |
These are physically at the ends of the disk, on either side of the remaining unpartitioned space. When possible, I highly recommend setting aside a large chunk of unallocated space for future needs. Better to keep one's options open than try to predict the future.
When you have multiple disks but no RAID, it can be worthwhile to arrange partitions to keep the spindles busy or at least minimize contention, which is why I put /var and /home on the second drive.

| 4G for swap is an whole lot, I know what the rule of thumb is, but that rule does not really apply if you have a lot of RAM. If you have more than 1GB of RAM, then anything more than 512MB of swap total is probably a waste, and even 512MB probably is as well. On my system, I have 2 GB of RAM, and I have never used more than about 100MB of swap. |
