File System Sizes

Faisal Aljundi — Sun, 31 Mar 2002 10:01:11 GMT

Hi,

I need to know how to configure the /, /opt, /var, /storage, /faisal, /database at the bigging while i'm reboot the system and reinstall 11.0 from the CDRom [not from the SAM].

What about if I decide to make the first Hard Disk for the OS and Openview Operation application and second hard disk for Oracle Database.

How I can do this?

I know it in NT and Solaris env. but HP-UX look like very diffecult when i'm installing the new OS [HP-UX]

In the installation you have the chance to configer and resize those.

You can create 2 Volume group. One for the OS the other for Oracle.

Are both disks in use? pvdisplay /dev/dsk/cxtydz on both disk,what do you see.

If one disk has not been assigned to a vg.
You can vgcreate a new VG then lvcreate/lvextend and newfs to create a new file system.

Hope this helps.

Hi

thanks for getting back with the spec. Now subject to the Oracle database not being big I personally would take one of the two following options: one disk with o/s and oracle mirrored to second disk if MDUX is available. Second option disk1 for o/s disk2 for oracle.

start off by booting from the installation CD and doing a standard default installation using one disk. The installation procedure will build all the standard file systems for you.

If you have the mirror disk s/w utility create a new file system for oracle on the first disk using sam otherwise create a new file system on the spare disk.

If you dont wish to use sam for the later please let us know what the size of the filesystem needs to be for oracle and if you have mirror disk and we will post a set of instructions to build the oracle filesystem.

When you are installing, you are presented with a text menu with tabs across the top. Since the install is only concerned about VG00, there is no need to worry about Oracle at this point. Once you have picked the bootable disk, move the cursor over to the FILESYSTEMS tab and start changing the values for the different mount points. Some useful sizes:

/ = 200 megs
/stand = 85 megs
/usr = 1000 megs
/opt = 1000 megs
/var = 1500 megs
/tmp = 250 megs
/home =

Now these assume a big system (the L1000) with big disks (9gb minimum). Be generous with /var especially if the L1000 will be a PC printer server or a lot of email goes through the machine or other applications need a lot of temp space.

NOTE: In the menu, once you select a filesystem to be changed, be sure to change the source-computation to FIXED, then enter a value, press tab and then type m (for Modify) so the changes will 'stick'.
