[Orca-users] Multiple Disk Space and Inode Plots

[Julian R C Briggs]

Dear Blair,

The Multiple Disk Space and Inode Plots bug is a significant problem
for us...

We have moved disks around actively in the last quarter and now get
7 versions of Disk Space and Inode Plots, as the appended fragment
of the Orca Daily cedar shows.

Our orca server (ie the host which generates the graphs) is low spec
(Sun Ultra 1) so generating the orca graphs (for our 4 servers) puts
a significant performance hit on it.

I would really appreciate any hints on a workaround until a bug fix
appears.  Ie is there a way of cleaning the rrd files so orca
generates just 1 disk size/inode plot?

Thanks

Julian Briggs
