Re: ReiserFS over MD?

I agree with EZ, on a production system, I wouldn't use JBOD to hold 
data, nor back it up, hard disks these days are not that expensive, what 
more, on the suggested deployment, should a disk fail you will loose the 
content of both disks, whereas using any sort of redundant array, you 
will usually have a chance to recover most of the data.

I would never use raid0 on a production system. Just not worth it.
However, both home system and raid1 are another thing.
BTW - You cannot boot from a raid0 partition. You need to have your 
/boot on a non-striping raid (that is, none, or raid1).

Quoting Ez-Aton, from the post of Mon, 20 Dec:
 

as raid1. I can have swap partitions without RAID and the backup
directory as RAID0 instead of RAID1 for instance.
questions -
1. Is that the best methodology to follow? any other recommendations?
     

I would have recommended using raid0, but once upon a time, when a disk 
crushed, and I lost 80 gigs of data (these were the days when 40 gigs 
were large disks), I saw, or better - felt the negative results.
   

that's why I use that for the backup.
I stage a backup of the site on the RAID0 space, and then RSYNC it away
from there. plus this is a temp thig. I'm pretty sure we'll use a third
drive for swap and backup one day.
 

2. Am I risking anything by installing reiser3 (kernel 2.6.8) on an
     

MD device?
     

Should be no reason.
   

thanks, that's the part that had me worried the most.
