Hi,

I installed Ubuntu on my pc which is having 1TB HDD,
I created /,/home,/boot,swap,/opt, and /var partitions.
After completing of installation i checked with df -h command it gives output like this

/dev/sda1 184G 3.3G 171G 2% /
none 1.7G 268K 1.7G 1% /dev
none 1.7G 4.7M 1.7G 1% /dev/shm
none 1.7G 1.8M 1.7G 1% /var/run
none 1.7G 0 1.7G 0% /var/lock
none 1.7G 0 1.7G 0% /lib/init/rw[/B]
/dev/sda5 4.6G 198M 4.2G 5% /boot
/dev/sda6 161G 191M 153G 1% /home
/dev/sda8 92G 436M 87G 1% /opt
/dev/sda7 276G 21G 241G 8% /var

what's this none partitions and why these partitions created automatically, what data store here,
if we create partitions manually is these partitions are compulsary.
In linux we cant create only 2 or 3 partitions (like in windows C, and D) ?

Thanks

you can create only a couple of partitions, you only need / and /boot really, and if you're using LVM, you can make two partitions, one tiny one for /boot and then an LVM partition to contain all the other filesystems. The point is that it's better to use multiple filesystems in a well built system for all sorts of reasons.

the "none" ones are virtual filesystems where hardware devices and kernel hooks are mapped to filesystems. They do not exist on your disk at all.

and can I suggest you take time to ask yourself "What the F&*% is C:?? What?? and D:? That's rubbish!". The more you see UNIX filesystems, the more painful and arbitrary you're likely to think windows bizarre unquestioned and highly inflexible conventions really are.

You actually only need / and SWAP. It is advisable to have /, SWAP, and /home.

I do all of mine with a 10GB /, 2 GB SWAP, and the rest as /home.

k3lt01, I would suggest that that is a pretty poor layout if these are long term server installations. I'm only basing that on the word "all" though... and you don't actually *need* swap at all...

@ acid_kewpie, this is posted in Linux newbie, the OP as far as I can see hasn't mentioned a server.

I'm not going to get into a picky discussion about this when all I was trying to do is help. Have a good day.

hey uuuu
what that language ur using........
R u dont understand what i mentioned,
Is that's the way u will give replay, if you dont understand post the replay but this is not fair.

To be fair to acid_kewpie he is using understandable English, which is very different to what you typed up. Please try your best in technical forums to use correct literary English instead of resorting to txt spk.
