cnfs buffer redistribution

[grant basham]

Running inn-STABLE-20010426 on x86 Linux 2.4.2-2, RedHat 7.1
cnfs with   ovmethod: buffindexed.


I need to redistribute usage of my cnfs buffers to make more room for large
articles.  Currently I have 40G for LARGE, 40G for rest of ALT, 40G for all
the rest (MAIN).  I would like to consolidate storage that now goes in ALT
to go in MAIN.  I would then like to use the space in the current ALT
metacycbuffer as additional space for LARGE.  It would be great if I could
do it without rebuilding history/overview or clearing my storage buffers.

First choice would be to just  eliminate the ALT metacycbuffer (mcb) and
add its buffers (cA-cT) to the LARGE mcb in cycbuff.conf

If that will not work,  can I change newsgroup: to "*" in all mcb and
manipulate size: to take [ 50000,large ; large ; no size-config ]
in [ LARGE ; ALT ; MAIN ] in storage.conf?

Any other suggestions?

Any advice is appreciated.
