Well, what I would have done in your situation would have been to boot from CD, mount the filesystems, and clean up your root partition, including copying parts of your root filesystem to your almost empty /export/home partition,creating some temporary symbolic links and getting your system to boot before trying to reorganize your disk geometry.

Some of the advise given was well intended, but it was not given in a safe step-by-step way to insure a novice would not make a serious error. I apologize that the earlier advice from forum posters was not easy for you to follow. You may have made an error that will cause you to have to reinstall. On the other hand, before doing so, I recommend you boot from CD, set your disk partition back to the original size, and run a filesystem check / repair against your entire filesystem first. If that works without problems, we can then offload some of your space problem with symbolic links to get you booted.

... From my mobile..... Sorry for any typos.

Thanks Neo, i will have to do another installation again. For future purpose when you say that i should boot from cd to rectify this problem, do you mean that i
* should boot in to the single user and then rectify using command prompt
or
* I should pretend doing an installation and then using the preserve data option before doing another custom layout the slice sizes.

Pls if this above are wrong can you pls enlighten.

Thanks all for your input

Before you try to reinstall, unless you really want to reinstall, you should attempt to repair by the above.

Boot from CD and change the disk partition back to the original size, mount the partition and run fsck to check and repair errors.

If all is OK, proceed to the next step I mentioned.
