I'm going to configure Debian GNU/Linux with software RAID 1 and I think

equal priorities, linux kernel will mirror swap area between different
devices. Is that true ? I mean kernel 2.6.32 and 3.2.x.
I guess you mean these two different approaches:
1. Swapping on RAID
https://raid.wiki.kernel.org/index.php/Why_RAID%3F#Swapping_on_RAID
2. More on Linux RAID: Swap On RAID?
http://blog.taggesell.de/index.php?/archives/53-More-on-Linux-RAID-Swap-On-RAID.html
I'd go for the second: put swap under a raid-1 device; without going too
much deep into the issue, it makes more sense to me.
Greetings,
Hi Camaleón.
I did so - put swap on RAID 1.
I haven't found information about linux kernel possibility of mirroring
swap automatically so this is probably misunderstanding or mistake.
Best regards
Georgi
