On a 16 gb machine that's nothong near a real solution to me. Loosing =20=
13gb of ram is not what i want.
Also, i've tried using (previously i was using raid10) RAID5 on a test =20=
box, and have run a lot of stress on it ( buildworld -j16, iozone, =20
bonnie++, backups and etc). It didn't crash on me yet. I'm in process =20=
of moving the box to production to see if it won't crash there.
But even if it works, raid1/raid10 is what i, and imho most people, =20
use, so we need it fixed anyway.
