Handling Andrew project disks

project disks: /afs/andrew/mcs/physics/stm_data, /afs/andrew/mcs/physics/stm_data2

backup:

To mount your backup volume, execute the following commands:

	cd < project volume location >
        fs lv .
        fs mkm < where to mount the backup volume > < backup volume name >

To find the , you first have to find the file
system's name for your volume with the 'fs lv' (File System, List
Volume) command.  The name of your backup volume is the same as the
original volume, with a '.backup' appended.

For example, to mount the backup volume for the mitosis volume as
'OldFiles':

	% cd /afs/andrew/mcs/bio/mitosis
	% fs lv .

	Volume status for vid = 1234567890 named mcs.bio.mitosis
	Current disk quota is 10000
	Current blocks used are 1234
	The partition has 123456 blocks available out of 987654

	% fs mkm ./OldFiles mcs.bio.mitosis.backup

symbolic links:
ln -s < project volume location > < symbolic link name >
e.g., ln -s /afs/andrew/mcs/bio/mitosis ~/mitosis
