Help to Grow the Size of volume
I have a 146Gb drive and want to grow the size from 12G to the max available left. I think 20G is being used so I want to max out from 12 G to 126G. Is this possible? Can you help with the command.

Code:
root@WRPDWI6k-BU # df -h                               
Filesystem             size   used  avail capacity  Mounted on

To check how much you have etc. you should issue a vgdisplay and lvdisplay. Your VG will be the whole size of the PV ie. your disk. So the vgdisplay should show a lot of free units.
To actually increase the size of a FS you will have to use something like resize2fs for ext2/3. For ReiserFS you will have to use resize_reiserfs

Afaik you have to umount the FS you want to resize. Not sure if this is the case for all implementations of LVM2 on Linux but I think it will tell you when just fire off a resize 1st.

There are also graphical tools available to handle your LVM, for example gparted.

This looks like a Solaris system so these commands don't apply. I think your options are very limited because your not using using SVM and everything is in the root file system. The easiest thing to do is allocate space from a free slice and create a new file system. This may or may not meet your needs. Converting to SVM would give you the most flexability. In a nut shell: convert the root slice and then attach the slice with the remaining free slice, then growfs. Personally I don't like everything in the root file system though.
