Re: Which filesystem for 40000 RRD files

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.
