How to set up disk space on Sun Sparc machine correctly. Please help.
I am not very good at UNIX and seek help here. I tried to install
Oracle 10g on a 64 bit Sun sparc machine with solaris 10 as OS. After I installed solaris 10, the current file system on the machine looks like this:
/dev/dsk/c0t0d0s05104758 4854293 19941897%/
/devices0 000%/devices
ctfs0 000%/system/contract
proc0 000%/proc
mnttab 0 000%/etc/mnttab
swap9718561024 9708321%/etc/svc/volatile
objfs00 00%/system/object
fd 00 00%/dev/fd
swap971184 3529708321%/tmp
swap970896649708321%/var/run
/dev/dsk/c0t0d0s73285899732601 324978071%/export/home
Then, I created oracle directory as /u01/app/oracle. It automatically
mount from /dev/dsk/c0t0d0s0. Now disk space in that partition is almost full (97%). I need to use /dev/dsk/c0t0d0s7 because this partition got enough space. If I create /u01/app/oracle under /dev/dsk/c0t0d0s7, will the mount point
be under /export/home? From file system angle, it will show directory
like: /export/home/u01/app/oracle? Please help me to figure out this part correctly. Thanks for your help.

Try to backup the data from /export/home to som safe place.
Unmount /export/home.
Resice slice 7.
Use format to create a slice 6 (for instance) with whats left.
Label the disk.
Do a newfs on slice 6 and slice 7
Remount /export/home on the original slice 7 and restore the data.
mkdir /u01
mount /dev/dsk/c0t0d0s6 /u01 (add it to the vfstab aswell)

Hi,
If You have the posibility to reinstall the OS, this
will be the easiest way if You're unsure about
the utilities. Use manual layout from the installation.
Anyway, here is an example of the other way to do it.
1-Add a second disk. (ie.) c0t1d0
2-Modify the vtoc as required (format)
ie.
root on c0t1d0s0
swap on c0t1d0s1
/export/home on c0t1d0s5
/u01 on c0t1d0s6
leave 32MB on c0t1d0s7 for metadatabase (SVM) - optional
3-newfs on s0, s5, s6
# newfs /dev/rdsk/c0t1d0s0
etc.
4-copy contents of /export/home to the new slice
# mount /dev/dsk/c0t1d0s5 /mnt
# cd /export/home; tar cf - . |(cd /mnt;tar xf -)
# umount /mnt
5-copy root filesystem to new root
# mount /dev/dsk/c0t1d0s0 /mnt
# ufsdump 0f - / | (cd /mnt; ufsrestore -xf )
6- Modify /mnt/etc/vfstab so that it will mount correctly
slice 5 for /export/home
slice 6 for /u01
# umount /mnt
7-Create the bootblock
# cd /usr/platform/`uname -i`/lib/fs/ufs
# installboot bootblk /dev/rdsk/c0t1d0s0
Now You would be able to boot from the other disk.
(might be typos above so please verify from man pages)
Good Luck
