Reconfigure root disk and upgrade OS

[thomgreen]

I have not been working too long with Solaris but lately have had many issues giving me a crash course. Here are my issues:

o root,usr and opt directory is too small - I need to resize the disk for these mount points:
/dev/md/dsk/d10 91919 81277 1451 99% /
/dev/md/dsk/d30 864751 797395 6824 100% /usr
fd 0 0 0 0% /dev/fd
/dev/md/dsk/d20 124330 73542 38355 66% /var
/dev/md/dsk/d40 124330 3468 108429 4% /tmp
/dev/md/dsk/d50 756655 688444 7679 99% /opt
/dev/md/dsk/d60 6644069 5804738 839331 88% /u01

o need to upgrade OS from Solaris 7 to Solaris 8. I would like to not have to re-install my Oracle Applications. Should I:
-Reconfigure the disk and upgrade.
-Install Solaris 8 and restore non-system(OS) mount points

o My system is a SUN E450 has 2G memory. 2 db's with a total of instance size of 1G. How much space should I have allocated to root,usr,opt,var,swap,tmp. Available space for these mount points would be 3G or 9G. I am working on the 9G and hopefully that is what I will have to use.

Hopefully this is enough info for a knowledgable reply. Any help would be appreciated.

save your data on tape or an other disk
reinstall OS
nota sol8 will place swap on the slice 0
you don't need a /usr partition, let it on /
you save space and you normally do not write on usr.
if you install forein soft (usually in /usr/local)
make a link to an other partition or mount an other
part on /usr/local, next time you reinstall the os
this partition will not be concerned.
