Hi,
My new A8N-E/AMD64 hardware came up the first time. SATA/DVD/CDRW
all seen. LiveCD boots fine. memtest86 has been running for the last
hour and looks good so far. All looks good so I'll start a Gentoo
install pretty soon.
I'm looking at LVN2 for this install. The main drive is 250GB. I'm
wondering a couple of things:
1) Should use all of the drive, other than the boot and swap
partitions, for the main LVN partition and then let LVN subdivide it
as needs come up as per the Gentoo-wiki on LVN2? This would meen, as I
understand it, that there would never been more than real partitions
on the drive.
2) Possibly make the main install partition something like 50GB and
use the balance of the hard drive outside of LVM2? If I do this and
later add a new partition within LVM does that somehow change device
numbering (/dev/sdaX) on the external partitions?
I don't know why I would do the latter, other than should LVM
become inoperable it seems that I could still get at the 200GB that
isn't within LVM's control. Since the hardware is new I don't know
anything about it's reliability yet and hate to go down a path where
data gets trapped in a few weeks if something dies.
QUESTION: Are there any performance differences between using LVM and
a standard partition?
QUESTION 2: does anythign about LVM2 beg for a 2005.1 LiveCD? Mine is 2005.0.
Probably I'll do #1 and just live with it but if there's a better
way to do it I'd like to hear what and why.
Thanks,
Mark
