Hi !
How should I partiton the volume group:
vg00: 8678 MB
swap: 1024 MB

How many MB??s should I use for:
/usr/local
/opt
/usr
/
e.g.:
/stand: 100MB
/var: 160 MB
/root: 30 MB
/usr: 220-771MB
/opt: 225-685MB

Please give me a example for partitioning the disk !

What are you going to be using this server for?
And what applications will be used.

Assuming that you have only one disk on the system.

/ -250MB
/stand -100MB
/var -400MB
/usr -1000MB
/tmp -250MB
/opt -1000GB
/home - 2000MB
swap 1024M

Still -2.0 to 2.5Gb free which can be used to create a seperate lvol.

I like T.G.'s recommendations with the exception of /var. Since /var gets all the patch traffic, 400MB can end up being full as soon as you put the Quality Packs on after the initial install. I generally go for around 1000MB.

Pete,
when I read your answer first time I read this as
can end up being full moon
and not as
can end up being full as soon

Anyway you are right,put some more with /var

Thanks

Thanks for your requests !
The values witch I have writedat first,were from the HPUX Installation Docs.
Can you describe me the directories funktion in system for:
/var
/opt
Should I create a volume /usr/local ?

main functions of the file systems

/var --accounting,auditing information,patch installations.

/opt -- software/application installations hold this file system.

/usr --This holds all man pages,executables of OS.

There is no need to create a seperate volume for /usr/local unless it becomes huge making administration job hard.

Thanks

/var contains log files, some configuration information, patch data, print spool data - things that need to be kept on a semi-permanent basis. /opt contains application software. As far as /usr/local is concerned, it's pretty much up to you. I don't create one.

I think the forum's recommendation for /usr is a bit tight. I'm running HP-UX 11i on an s700 (C3650) and all I've got is MTOE plus MirrorDisk/UX (plus CD recording s/w, but that's in /opt). Anyway, having installed from the March 2002 installation media, my /usr utilisation is 907880. Even if it installs OK, with just 1 GB of /usr, you may find a big set of patches will transiently blow the limits.

I also tried the December 2002 media, which increased /usr utilisation by about 200 MB. Since this also sets the HFS blocksize to 64K, which then stops dce working (needs an updated libdce.2, which at the time (April 2003) was not available as a patch) I've reverted to the March 2002 media.

I currently set /usr to 1600 MB, but I could probably reduce this to 1300MB.

If you want to run mathematical applications, you might want to consider TCOE, because this comes with high-performance maths libraries. I haven't installed TCOE, but I'd be surprised if it required less in /usr than MTOE.

I wouldn't trust the filesystem sizes calculated by the installation utility - I've had cases where they didn't leave enough space in /var and/or in /usr. The errors aren't always easy to see, either.

Hi,
Sorry for my late reply. Do you use an external fileserver for data storage. If not, I would create one volume for stand (100MB) and the rest in root volume / . FEM rograms as Abacus is extremly data intensive and dividing your disk in small partitions will perhaps result in that the data from one single job will not fit in any of the partitions.
