Hi everybody.
I early have studies Solaris/OpenSolaris....
My problem: My partition is using 86% of Hard Disk. I want to expand my partition to use 100% of Hard Disk, but don't error data on that partition. Can everyone help me???

Thanks.

format> fdisk

Total disk size is 3583 cylinders
Cylinder size is 4096 (512 byte) blocks

Cylinders
Partition Status Type Start End Length %
========= ====== ============ ===== === ====== ===
1 Active Solaris2 1 3070 3070 86

SELECT ONE OF THE FOLLOWING:
1. Create a partition
2. Specify the active partition
3. Delete a partition
4. Change between Solaris and Solaris2 Partition IDs
5. Exit (update disk configuration and exit)
6. Cancel (exit without updating disk configuration)
Specify the percentage of disk to use for this partition
(or type "c" to specify the size in cylinders). ^Cformat> ^C

Have you looked into growfs ? I think that what you are looking for
growfs(1M) – non-destructively expand a UFS file system (man pages section 1M: System Administration Commands) - Sun Microsystems
