Hello,

Today I was checking the hard-disks on my Fuel with irix 6.5.28m. There are 2 harddisks.
- Hard-disk one containing one partition and mounted as the usr/people.
- Hard-disk two is the 'systemdisk'.
However it has two partitions.
+ The first partition is mounted as '/'.
+ The second partition is unmounted and has a size of 20MB.

I didn't find the use of this 20 MB partition. Did I something wrong at the installation, or is a swap partition, or has it some other functions ?

Thanks in advance for the info.

What does mount say?

That's not the question. I know perfectly what mount means.

I only want to know why IRIX made this partition, or does I made an error in the installation process.
And if IRIX made this partition, what's the reason ?

Hello,

I decided to reinstall the OS and repartition the HD.
Installation is to be done over network. Now I got new -other- problems (with sash and fx.64), but no time to solve.

irix doesn't create any partitions. that's up to you before starting the installation. the first post there has details: viewtopic.php?f=10&t=11322&p=7348669

in addition to that i'd recommend before leaving fx to resize swap and sync the label.

Chances are it's swap and is where your miniroot goes. dksxdys0 is usually root and dksxdys1 is usually swap. Should be in the fx manpage.

Seems small for swap - from memory, though it's a while since I've had to fx a disk, swap starts at 128MB by default (but perhaps smaller if the disk is small?). That said, in this case a previous user might have reduced swap, thinking they had enough RAM and a better use for 108MB of storage!

Mark,
In what context do the two partitions show up? what were you using to check the disks?

That's definitely too small to be useful as swap, by way of example my Blade 2500 came configured from Sun with 10 gig of swap.

I've wondered about this ... in the days of 4 megs of RAM, a big swap made sense. But with 8 gigs of RAM and you haven't written memory to disk since dinosaurs roamed the earth, what's the point of a big swap ?

Har... :lol:

I think it's paranoia; since Solaris has the authority to start killing user applications when RAM and swap are maxed out. Where I work, we load some truly gigantic models into apps like DYNA3D and even with 12 gig of RAM on my Blade 2500 it does occasionally thrash... :shock:

the 20mb are the / partition if the usr template of fx is used.

During use IRIX usually mounts a swap file on the main filesystem for swap (similar to what Windows does). You can enlarge the swap partition in fx if you know you'll be using swap often and save some time (since it doesn't have to go through the filesystem), but most people have enough RAM to not need to bother.
