I note that in the debian RAID is says to make two swap parititions of equal priority,
A better way is to layer swap on a proper mirrored raid device instead, this way the machine will still boot if one drive fails,
rather than complaining about missing swap...

I use dmraid as you see in. http://www.net-forums.net/forums/Mounting_Ntfs_Partions_On_Raid_0_Device-t19 791.html
my mainboard is MSI RS480 M2 http://www.msi.com.tw/program/products/mainboard/mbd/pro_mbd_detail.php?UID= 639 CPU AMD 64 3000+ HDD Segate 20G IDE Maxtor 160G SATA x 2
My mainboard have silicon image SATA Raid controller building. Then I compile kernel 2.6.11 and enable data-mapper module.
And I create Maxtor 160G x 2 to raid 0 . [root@ares ~]# dmraid -s *** Active Set name : sil_afaeafbgccbgb size : 640339968 stride : 64 type : striped status : ok subsets: 0 devs : 2 spares : 0 [root@ares ~]# sfdisk --show-size /dev/mapper/sil_afaeafbgccbgb 320169984 [root@ares ~]# sfdisk --show-size /dev/mapper/sil_afaeafbgccbgb1 320167386
Every thing seem to be OK, but when I mount /dev/mapper/sil_afaeafbgccbgb1 and use command df.
[root@ares ~]# df Filesystem 1K-blocks Used Available Use% Mounted on /dev/hda3 36384656 2596712 31939668 8% / /dev/hda1 101105 46194 49690 49% /boot none 504892 0 504892 0% /dev/shm /dev/mapper/sil_afaeafbgccbgb1 160074724 17954072 142120652 12% /home/topwarez.com/torrent/httpd/users
Why the system show a half size (160074724 ) of my raid array.
