Hello,
Question 1:
Let say if I wanted to use RAID for my 2 HDD to install RH8, I would create a RAID partition over hda and hdb into a single partition, is this possible? Which RAID I should use in order to gain speed only but do not care about the backuping or mirroring stuff as described in the documentation? Currently I have this structure for easy upgrade in the future w/o lossing my configurations and installed software:
/boot - /dev/hda1 - 70MB (minimum for redhat)
swap - /dev/hda2 - 512MB (2X memory)
/ - /dev/hda3 - remaining of hda
/var - /dev/hdb1 - 3000MB
/usr/local - /dev/hdb2 - 3000MB
/home - /dev/hdb3 - 3000MB
/work - /dev/hdb4 - the rest of hdb
Any advices?
Question 2:
According to RH8 recent errata, we can set the DMA option in /etc/modules.conf to enable CD-ROM access to DMA access. But one thing I was curious that why RH8 does not enable HDD DMA access of 32-bit I/O where we actually have to use command such as:
# hdparm -c1 /dev/hda
to enable the 32-bit I/O, and need to put those line under /etc/rc.d/rc.local and get it activate during system bootup? Is there a better way to do this or is this the best way to do it w/o re-compiling the kernel.
