Extend / (root) in HPUX 10.20

[Silvio Pioli]

Hi to everybody,
I was trying to install gcc compiler on a HP-UX 10.20 Server when I encountered the following problem:

ERROR: The used disk space on filesystem "/" is estimated to increase
by 192468 Kbytes.
This operation will exceed the absolute limit on this volume
by 129717 Kbytes. You should free up at least 137254 Kbytes
to avoid installing beyond the minimum free threshold of
available user disk space.

My root seems to be too small and the only thing to do is expand it, I guess. There are alternative solutions?

Now, here are a list of information about my system:

I thought to move all LVs preceding to the lvol3 (lvol4, 5, 6, 7 and 8). However the c3t5d0 belongs to another VG, so I tried to create a spare disk but that failed:

# pvcreate -f /dev/rdsk/c6t8d0
Couldn't stat physical volume "/dev/rdsk/c6t8d0":
pvcreate: Couldn't open physical volume "/dev/rdsk/c6t8d0":
No such file or directory

What can I do to solve this?

Any suggestion will be really appreciated.
Thanks

Your problem is that gcc is trying to install into the root volume (/). It should not be doing this. Check the install, find out exactly where it is installing to and change it to some place with enough free space.

What is the output of "vgdisplay -v"?

It looks like you have two 18.2GB hard disks. The boot disk is probably used up completely, I counted 16.3GB in use and you probably are using some for SWAP.
The second disk is used exclusively by /home2 and may have some unallocated space. /home2 has a lot of free space, if you don't need that exclusively for user space you could install gcc there.

@Pete Randall:
What do you exactly mean with "Check the install, find out exactly where it is installing to and change it to some place with enough free space"?


I have a depot file and I'm trying to install with "swinstall" command. I don't know how to change it.

[Dennis Handly]

>I have a depot file and I'm trying to install with "swinstall" command.

From where? Is it trying to install in /opt/?
You might be able to create a symlink under /opt/ to use space elsewhere.

[Silvio Pioli]

As you can see above, in the fstab file I 've already done something similar, in fact the lvol5 is mounted on /home/opt, not in /opt as it was before.

This is the installation log file:

You'll need symlinks for each /opt/ tree. In fact you may want to move some existing trees there before you start.

Unfortunately the DSA will not realize that you have symlinks in place for your new software, so you may have to use "-x enforce_dsa=false", provided you have all the symlinks in place for each new tree.
You can see your new files by:
swlist -l file -s /path-to-depot

[Silvio Pioli]

I did it by installing under /home2 where I had much more disk space. I used swinstall command and selected the right target by selecting Actions->Change Target from the main toolbar.
Thank you everybody.
