[auton-users] System Update

[Michael J. Baysek]

Hi Lab,


The majority of the work is now complete, and the system is safe to use 
again.


Everything Auton now lives in /auton.  BigPapa is also gone, and as 
such, can no longer going cause your fingers to stretch for that nemesis 
shift key every time you type it.  Your home directory is now 
/auton/home/yourhome.  The data directory is in /auton/data, etc.  You 
will notice that all top level /auton/* directories are all symlinks 
into the /auton/volumes directory.  You should never use any directory 
in /auton/volumes/* directly, as this is where the backend disks are 
located.  The idea behind this is that we can move, say, 'home' or 
'data' to a new set of disks without moving it from the /auton/data 
location.


You'll notice that the df command no longer accurately reports the free 
space.  It should not be a concern, but if you like, you may check the 
disk space by viewing the /auton/diskspace.txt file. 

Also, anything put on the /auton/data or /auton/archive directory will 
be stored with realtime compression.  This will allow us to store 
approximately twice as much data on the same disks.  Use archive to move 
old or static files out of the way.  This will make life easier for the 
backup system.


The location of CVS has also changed to 
lop1.autonlab.org:/auton/repos/CVS .  I have already updated all of your 
shell environments and "~h/" sandboxes to use the new CVS location, but 
if there are sandboxes in other places, let me know so I can make a list 
of them and take care of those too.  If you are using CVS from a laptop. 
please set your environment as follows:

export CVSROOT=lop1.autonlab.org:/auton/repos/CVS
export CVS_RSH=ssh
And replace all ~/h/*/CVS/Root files with one containing 
"lop1.autonlab.org:/auton/repos/CVS"


There will be a few things like WebCVS and Windows file sharing which I 
still need to take care of but, 95% of systems are go.  There will be 
documentation updates on the Intranet in the coming days and weeks which 
will explain how to get the most out of the new setup.  Please email me 
with any questions you have in the meantime.


Happy New Year!


Mike
