[mrtg] Which filesystem for 40000 RRD files

[Leonardo Reginin]

Hi Pavel


Just thinking here.

Maybe another fearless approach, could be add some extra memory to the 
server and build a memory disk to keep the rrd files. This approach will 
lead to a couple of scripts to keep asynchronously SYNC the MD and the 
HD as well as LOAD the MD from the HD at boot time.

The penalty would be the loss in an unattended power-off, but I think 
that it could be the price for pay.
