I use a full tower with the drives in the top half. You may get away with a half tower but the circulation is usually worse.It'll be noisy and, more worryingly - very hot!
Yeah I'm obviously worried about that, figured there's only one way to find out ...
there's probably no way around the noise ... for now until i can make a backend
in a basement or somewhere. right now i have an apt. i'm beginning to think i'll need to stick the fileserver in a tower/desktop case.
what type of case do you suggest as a minimum for raid 5, + OS drive?
ie. 3-5 drives.
I cut a circular hole in the top and vent via a 12cm fan.
If you go for a bigger case then you can put sound absorbing material (which should alleviate the hard disk whine) and bigger (hence slower and quieter) fans in it. If you can move air through the case then heat should be less of an issue.
Given the 250 also pumps out heat, as will any graphics card, this may be best although it obviously won't sit on a shelf looking cute.
You sound like you're spending money carefully so maybe do what I did and get a cheap beige tower and paint it (with car-paint). It looked surprisingly good. I then put a branded 550W PSU in.
if i change my route from microATX behemoth I'd likely make my current desktop computer a file-server/myth backend and purchase HWmmm - if that speed is reliable then it's fine - but if you end up with the connection dropping with an nfs mount trying to write then my experience is that ivtv goes AWOL. I'd avoid a wireless connection unless you feel it's as stable as wire.
for a frontend.
there's a problem with that.
1) no wired network to bedroom, just wireless 802.11B 5-8Mb/s?
To emphasise - the speed is generally not an issue.
nope.unless i use the 'missing' trick?nope - can't do that :) You can start with a 3-drive raid5 with 1 missing (ie 2x300Gb) and add a 3rd later.
But you'll have no redundancy until you buy the 3rd drive.
You also can't 'add drives as time goes by' to a raid 5.
The only way to add drives is an unsupported program called raidreconf or using the (supported) EVMS solution.
Sean's idea of lots of mini-raid5'ed partitions is very interesting though. I haven't thought it through. I think you could do it just using the lvm 'move blocks' approach (ie without needing to repeatedly shrink/grow the filesystem - just one growfs at the end).
I'd rate it as lvm/md experts only (which isn't that hard TBH)
yes.
I have 6x250 Gb sata drives making a raid5 array
The 6th 'spare' drive is a 250Gb partition on a 300Gb PATA drive - and I
have had it as part of the array with no issues at all.
dang. what case do you use? and powersupply/fan?
as above :) And it's just a fileserver.
