Subject: [gentoo-user] RAID/LVM machine - install questions
Date: Fri, 19 Mar 2010 23:07:49
1 Hi,
2 I'm starting to put together a server-type machine with multiple purposes:
4 1) MythTV server
5 2) General backups for another fast machine I'm going to build
6 3) Wife's new desktop
8 Since all of these requirements are pretty modest but I want high
9 reliability I'd like to do software RAID with (I think) LVM on top of
10 that. I've not decided yet exactly what RAID type to use, and I know
11 nothing about LVM, so I'm reading here to learn:
16 The LVM Install doc is pretty clear about not putting these in LVM:
18 /etc, /lib, /mnt, /proc, /sbin, /dev, and /root
20 which seems sensible. From an install point of view I'm wondering
21 about RAID and how I should treat /, /boot and swap? As I'm planning
22 on software RAID it seems that maybe those part of the file system
23 should not even be part of RAID. Is that sensible? I always want /
24 available to mount the directories above. /boot on RAID means (I
25 guess) that I'd need RAID in the kernel instead of modular, and why do
26 I need swap on RAID?
28 The most important task of this machine is to keep data safe. If
29 the machine has a hardware problem and is down for a day or two that's
30 not going to be a big problem as long as the Myth recordings, my
31 wife's home directory and the backups I'm doing and placing on the
32 machine are relatively safe. the processor is going to be WAY overkill
33 with 8 cores but it hardly makes financial sense to go smaller as
34 maybe I can even run some computer cycles on it, like building binary
35 packages for my other machines or something like that.
37 Interested in whatever thoughts folks have about the best way to
38 set this up. If I haven't outlined the requirements well enough let me
39 know. I'm at least a week from starting to build the hardware so
40 there's no rush on this but maybe comments will effect motherboard
41 selection, etc.
43 Thanks,
44 Mark
