[Orca-users] Multiple disk space percentage graphs

ZiZo -- try removing yourself from the list by going here:

shouting one you just sent ;))

Tonij, I guess you missed one of my emails on the private thread --

I'll repeat the answer here:

I would keep your 0.27 around, and put r525 in a different place 
(perhaps on a different machine, even, if you can manage that).  That'll 
give you a chance to play around with it and verify that it does work 
better for you.  Migrating your data is a simple matter of moving (or 
coyping) your orcallator data files from the 0.27 directory to the r525 
directory.  In fact, you can even have the two revs share the same raw 
data directory, as long as they're using independent rrd directories.  
You can accompplish this with a symbolic link.

As for filesystem representation in Orca after you've removed them -- if 
they're in the raw data files, they're going to make it to the Orca 
graphs if your plot {} stuff says they should.  If you want to filter 
them out, you should add regexp's to your plot {} configuration in the 
data line, much like this line filters out my Veritas checkpoint 
filesystems (whether they're current or old):

    data            mntP_(?!/(?:vxckpt|checkpoints|veritas))(.*)

(didn't I post something about that earlier in this thread?)

Hope this helps,
