how to set the temporary disk space

[Nino Guba]

hi newbie question:

hp just installed fine. assigned 1GB for /tmp. but when I try to install using swinstall it keeps saying not enough disk space for temporary disk files.

I have tried changing /usr/tmp to link to a tmp directory on a different disk with ample space.

I was trying to do the same for /tmp but cant. Says drive is busy.

Is there an environment setting i can set to point to a different directory for tmp?

Thanks in advance.

Hi,

the env variable is TMPDIR.

export TMPDIR=/some_new_dir

Hope this helps.

Some progams will use the TEMP variable

TEMP=/other_location; export TERM


A 1 gig /tmp space seems plenty large.

When installing Oracle, I have had to remove left over files from failed installs to get enough space.

Look at /tmp and see if you need to remove some forgotten trash.
fuser -u /tmp/* Will show files that are open and that you should not delete.

I have a utility that remove /tmp files that have not been accessed for more than 12 hours. The utility also has an exclude list.

As Rory mentioned, 1 GB for /tmp should be plenty large enough - my /tmp is 204 MB and I have no problems with swinstall. What is it that you are trying to install and exactly what is the error message that you get?

I've tried setting those environment variables but still getting the error message:

A file I/O error has occured on this system. Make sure that you have enough disk space in the directory used for temporary disk files. This directory is usually "/usr/tmp" or "/tmp".

I check those directories and there are still almost 1GB free space.

This error message pops up when I click Ok after specifying the source for the swinstall (via SAM)

Any other suggestions?

What I want to install are UserLicenses from the Extension Software CD.

I dont think installing this requires my TMPDIR to be large. Maybe my mount parameters for the CDROM are at fault?

The entry in /etc/fstab is:
/dev/dks/c0t2d0 /cdrom cdfs ro,suid 0 2

[Pete Randall]

Take a look in /var/adm/syslog/syslog.log to see if there any error messages there related to I/O errors. Also check the output from the dmesg command for the same.

Can you write to /tmp /var/tmp from the command line.

echo "hello" > /tmp/xxx
echo "hello" > /var/tmp/xxx


I/O error doesn't sound like a space problem.

check perms on /tmp /var/tmp
drwxrwxrwt 3 bin bin 3072 Jan 28 08:20 /tmp

[Nino Guba]

ok i narrowed it down to selecting Local CDROM as having the problem.

no problems writing in /tmp and /var/tmp. permissions are ok.

can you see any problems with my mount options for the cdrom?

[Rory R Hammond]

I did not see you mount syntax

I have a directory:
/CDROM

My CD drive has an address:
/dev/dsk/c3t2d0

I mount the drive with the following command:
mount -r -F cdfs /dev/dsk/c3t2d0 /CDROM

and then run swinstall

I tried your mount options but still the same. I dont think my CDROM isn't working since I just used it to install the OS and mounting it and then listing the cdrom's contents is fine.

[Rory R Hammond]

If "mount" shows the CD mounted and you can do a ls /CDROM/* (or your location) and list the directory, And you can look at the contents of file. (cat README, etc) Then the I/O error might have to do with something like an incorrect path in your swinstall directory string

ioscan -fnC disk should show your CD hardware path


Rory

[Nino Guba]

No problems with hardware path either.

Anyway, I was able to workaround the problem. Just unmounted /cdrom from the console and had swinstall's "Find Local CD" to do the mounting for me.

Thanks to you all!
