G'day all,
I have a box here.. it has a 2Ghz processor and 1.5GB of ram. It runs the entire OS over NFS and
it's sole purpose in life is to run 15 SATA drives in a Raid-6 with ext3 on it, and share that over
NFS. Most of that ram is sitting completely idle and thus I thought a logical thing to do would be
to stuff as much of it as possible into the MD subsystem to help it cache..
Are there any limits to the values living in /sys/block/md* and what might be the tradeoffs (if any)
to using what would normally be thought stupid amounts of ram for these knobs ?
This box does not get written to often, it's just a media streamer mostly.. but if I am writing to
it then it chokes just providing a 1Mb stream over the network currently. (It's on a 2.6.15-git11
kernel currently but I'm just upgrading to 2.6.16 now)
Regards,
Brad
