As I was installing patches on my Sun Blade 100 I received an error

The O/S. The system went to OK prompt. I have plenty space on 2 80 gig
drive. How can I go in and expand the partition so the O/S will load
at boot time without my having to reinstalling the solaris O/S.
Disk space problems usually come from /var partition being filled up.
If /var does not have a separate partition then /usr partition is used
up. The easiest way to do is to move /var folder to a partition that
has enough space.
# mv /var /export/home/var
Then mount this new folder as /var local filesystem (lofs). In /etc/
vfstab, add the following entry:
#device device mount FS
fsck mount mount
#to mount to fsck point type pass at
boot options
#
/export/home/var - /var lofs - yes -
If you had set up /var as a partition then you will have to remove
that mount point from /etc/vfstab.
Now this does not guarantee that your system will boot up. You may
still need to remove some patches.
That's neat, I didn't know you could it do it that way. I always
thought column 1 was for disk devices.
Still, I'd prefer to use a symbolic link:
cd /
ln -s export/home/var
I believe it will work as well as you'd like, without affecting
any patches.
I should also point out that with the new conventions in Solaris 10,
/opt is another partition that is likely to fill up. Every time you
add a new package, it wants to add itself to /opt. E.g., /opt/sybase,
/opt/apache, etc. If you didn't plan ahead, /opt will be in the
too-small root partition.
Same solution, tho. Move it to a partition with enough space and
create the symbolic link.
I thought using loopback mounts (lofs) was more robust than symlinks in
the face of broken package install scripts?


I don't know -- you broke over my knowlege barrier --

My quick research on the topic only shows it in reference
to mounting ISO images, so I'm entirely clueless.

<:-(
I would say avoid symlinks whenever possible, thats a old dirty fix for a problem from old times.

That is also one thing about ZFS I miss, no lofs instead one have to remount the fs but then it "disapears" from the original location (:

lofs makes it a easy to have the same filesystem on the servere as on the clients se below where tools is to be mounted in /opt/tools on all machines.

/export/u1/opt/tools/SunOS/5.10/Sparc
/export/u1/opt/tools/SunOS/5.10/i386

The if the server is a Sparc you lofs /export/u1/opt/tools/SunOS/5.10/Sparc -> /opt/tools

And the clients mounts /export/u1/opt/tools/SunOS/5.10/Sparc if they are a sparc to /opt/tools or i386
