Moving directories to their own partitions

[bxb32001]

Greetings everyone,

After reading the Debian install and security howtos, I've decided that I should move /var, /usr and /tmp to their own partitions, using the Knoppix home directory howto as a guide. Thing is, I don't know how my fstab should look like and how big the partitions should be.

I would like to ask for input for the layout I plan (below).

Partition sizes:

/tmp – 50 mb (or 500?)
/var – 3 gb (or 2?)
/usr – 4 gb
/ – 500 mb

Am I on the right track? Are these partition sizes okay or are they excessive? This computer is the one I'll be using for home. In the future I do plan on setting it up to host web pages as well.

fstab additions:

/dev/hda9 /usr ext2 rw 0 2
/dev/hda6 /tmp ext2 rw 0 2
/dev/hda7 /var ext2 rw 0 2


Do these entries look okay? Or should it be:

/dev/hda9 /usr ext2 defaults 1 2
/dev/hda6 /tmp ext2 defaults 1 2
/dev/hda7 /var ext2 defaults 1 2

I don't know what the numbers at the end mean... I just took these from various sample I found in LQ and Google.

Any thoughts?

How much space do you have to work with?

/usr is where most of the "weight" is; make it bigger if your planning on installing more packages.

60 gigs... It's an 80 gig hard drive but Win2K has the first 20.... I also have a second 60 gig drive I just mainly use for storing mp3s, pictures and virtual CD files... and that's around 30 gigs so I have around 30 gigs more to spare on that other drive.

I know that's a lot of room but I don't want to over do it though. I'd rather use the (spare) room for my work, my scans, mp3s and other stuff everyone else at home puts into my box.

Right now, I have an installfest bonanza on my box... Fedora, Knoppix, Gnoppix, Morphix... but enough of that. I just want one to get some work done.

I was actually planning on installing Woody but then it hit me that I may just as well install Knoppix and move the partitions around.

It also just hit me that I probably can't opt for a 500 mb / partition since the / directory is what I have to start with (can you resize that using qtparted?).

[turbinater]

can you resize that using qtparted?
Yes I believe so, although I have never tried it.


60 gigs
How much space is being used of that 60?

Do you have a home directory for every distribution, or a single home directory used by all distributions? If you're planning on having millions of distributions on the same box, it is a good idea to have an extra partition for your home directory.

By tha way, make sure your partitions(/usr and all that) are taggged for auto in fstab, otherwise you may have a few unexpected surprises.

[bxb32001]

Right now all of them have their own /home directories (and/or partitions).

I was trying them out so the scheme I used sufficed... now I'm past that and just plan on having one.

One sounds good. You may even want a second so in case something goes wrong, you'll have something to fall back on.

True, but I can always rely on the live CD can't I? I also have Knoppix on a FAT32 partition which I boot from a floppy... I think it's what you call a 'Poor man's install'.

Right now I'm worried about resizing the / partition. I've managed to resize my swap partition before so I know qtparted can do the job... it's just that the / partition has real data on it. Hmmm...

/tmp is really tiny on both my systems, 50MB should be fine. Everything else looks Ok, however I would go with journalled filesystems for *everything* except /boot. This is what my fstab entries look like:



/dev/hdb1 / reiserfs defaults,noatime,rw 0 1
/dev/hde11 /mnt/squid reiserfs defaults,noatime,noexec 0 0
/dev/hda2 /mnt/extra2 ext3 defaults,noatime,noexec,rw 0 0
/dev/hda12 /mnt/bkps reiserfs defaults,noatime,notail,rw 0 0


--The two numeric entries at the end are for dump and fsck, see ' man fstab '.

--I'd recommend two things with all that hard drive space: Dedicate a partition (20Gig?) for backups, and consider setting up a Squid proxy server. ;-)

--If you want more info on that, I'll be happy to send you a copy of my config and some basic instructions.
