Hi,
I set up a raid box a while ago and so far it's performed flawlessly...
unfortunately the group I'm in are outgrowing it. So I'm putting together a
new box and I've got time to test it and benchmark it before putting it into
service.
The machine is a PPRO 64MB Ram, vanilla SuSE-6.0 box, I downloaded 2.2.6, the
patches and the raidtools. Recompiled the kernel, wrote a raidtab, ran mkraid
and it all seems to work. (see attached raidtab, md0 is squid cache, md1
/home, md2 main raid 5 array)
/dev/md2 is raid5 across 4 WDC AC313000R's (I can only work with what I have in
the office) In the raidtab I gave it a chunk size of 128 and I used the
following mke2fs command.
mke2fs -b 4096 0R stride=32 -m0 /dev/md2
Which from what I've read, should be pretty alright... Basically I suppose what
I'm asking is "Am I on the right track?" I'd really appreciate some feedback...
because Once this is put into service It'll be our server for the next 12
months at least.

I haven't run bonnie on /dev/md2 yet 'cause it's still synching the array.
Thanks for your time and patience... And keep up the good work...
