 |
|
I noticed in this howto: http://gentoo-wiki.com/HOWTO_Gentoo_Install_on_Software_RAID that they're creating raid0 swap on a system that's otherwise raid1:
| Code: | | mdadm --create --verbose /dev/md2 --level=0 --raid-devices=2 /dev/sda2 /dev/sdb2 |
I would think that striping swap would create an unnecessary risk of data corruption in memory, which could really suck. What do you guys think? Why not raid1? I would think that would be preferred, especially on machines where the swap isn't frequently used... |

I put my swap *file* on RAID5... mostly because I'm lazy 
I suppose if you don't care if your machine goes down in flames you'd use raid0 anyway, so sticking swap on raid0 isn't any worse... but in my case I have enough RAM and swap is only an emergency buffer and the reliability I get swapping on raid5 is much more valuable...
Since anyone can edit the page feel free to... it's a wiki after all. If not fixed by the next time I read it, I guess I'll fix it (along with its "Prequisits"(sic)).
