You basically want to have only static files on the root partition, not files that are in a general state of flux. ACK. This will also keep fragmentation down and thus performance up. For Gentoo, it may be a good idea to put portage stuff on a separate partition because it uses tens of thousands of small files that provoke fragmentation. On my laptop I have one partition with two directories usr-portage and var-cache-edb that are symlinked to the respective places in the root FS. regards Matthias -- I prefer encrypted and signed messages.

[gentoo-user] Suggestions on partitioning HD
Hi again, I have 10G HD which I would like to use for my new LVM2 install following this guide: http://www.gentoo.org/doc/en/lvm2.xml I've decided to go with this doc using my physical partitions for /boot /swap and / and give the rest to LVM. So partitions /usr /home /opt /var /tmp will be using LVM I will also use JFS filesystems on all of them, except /swap offcourse. What is your suggestions regarding how much space to give to each? Your replies are appreciated as always. And yes, I know that my drive is small and old and I can shrink and expand those in the future, but, theoretically, this is developement laptop and I want to use it. -- gentoo-user@gentoo.org mailing list

Re: [gentoo-user] Suggestions on partitioning HD
1. Boot should be at most ext3, but ext2 is just fine (the only thing on this partition is kernel images and grub stages). Keeping to this will mean less problems at boot time (grub users can tell you nightmares about reiserfs /boot partitions, and I'd guess that jfs would be in the same category). 50 meg is a nice round number although you can do with half that (I personally use 100mb but I've got a number of kernels installed there). 2. /opt does not need to be a separate partition. Few gentoo things go there, so it is not worth maintaining a separate partition for (and wasting the possible space). 3. /home should be a separate partition, sized to your needs. 4. I'm from the old school where we believe /var/tmp and /tmp should be separate partitions. This is primarily before they were made partitions as a norm and were on the root partition; filling them meant filling / and also meant you would lose access to your box. 5. For gentoo I recommend using a separate partition for /usr/portage. It's hard to nail down a size for this as portage tree keeps growing and the number of distfiles you might have is in flux. Isolating it ensures that any growth issues are isolated to that branch. 6. /var is your choice whether to parrtition separately or not, but is probably a good idea. /var/logs will grow over time, /var/spool is in constant flux, but the rest will typically remain kinda static (note this depends upon the apps you use; mysql houses it's databases under /var by default, and apache/tomcat use /var/www so that can chane also. Sizing each of the areas is really personal preference; if you ask 10 different gentooers you'll probably get 11 different responses at least. Dave -- gentoo-user@gentoo.org mailing list

Re: [gentoo-user] Suggestions on partitioning HD
Thanks for your reply. So, if that were your system, how much space you would give to /boot /swap / ( eliminating /opt) /home /var /tmp and /usr? I just need rough numbers, so that my fresh install wouldn't get in trouble. I have 256 RAM and this is 10GIGs. Thanks again.

Ah, but it is a disaster waiting to happen. If you fill your root partition you'll have difficulty getting back into the box (you'll need your live cd to chroot into your system and clean out the disk). How can something like this happen? Syslog filling up /var/log. An influx of spam filling /var/spool/mail. Never cleaning /usr/portage/distfiles but continually downloading package updates.

I have 256 RAM and this is 10GIGs. Thanks again. General rule of thumb is swap = 2 x ram, so 512mb swap. That will leave about 9.25 gb left (must account for partitioning overhead). I would probably do as follows: /home - 2gb /var - 1gb, rebind a section as /tmp to keep it all under this partition. Assumes you are not using the PORT_LOGDIR option, if you are add another 1gb. /usr/portage - 1gb but you'll need to clean out distfiles regularly. Whatever is left goes to / Note that regardless of your partitioning, you're going to want to be very selective over what is installed on the system. For example, choose gnome or kde, but not both (and set appropriate disabling use flags), or better yet a thinner window manager like icewm or something without the bulk/overhead of gnome/kde (which will struggle anyway due to low memory).

It needs a minimum of around 35MB for the journal, not a good thing when space is at a premium and you want a small partition. Under the circumstances, I wouldn't have a separate /boot at all.
