I follow some documentation for building the software raid on my system: http://www.argon18.com/raid_openbsd.html http://www.openbsd-france.org/documentations/OpenBSD-raid1.html#deux
And the result is, I have 2 disk which are working in RAID-1. I build following configuration: Physical disk: 250 Go (2 x) Disklabel: wd0 and wd1 wdXa: 10 Gb wdXb: 512m wdXd: the rest of the disk => as far I undestand, the wdXa disk are needed to boot before starting the RAID. This are more or less lost disk place ? I build again the same disklabel on the raid0 disk: a: 20971853 235680435 4.2BSD 2048 16384 1 b: 1048576 256652288 swap c: 466350720 0 unused 0 0 d: 208649856 257700864 4.2BSD 2048 16384 1 i: 1000974 136512000 MSDOS j: 4017 235676418 unknown But the result is: a: 10 Gb d: 100 Gb i ???? j ???? When I start the system, I have the feeling that I'm booting on the wd0a disk, and not on the raid0a disk Questions: * how can I be sure I'm booting on the right disk ? * where are my 130 Gb lost place ? * where will the system write the logs down ? Wd0a or raid0a ? If those information are writing to raid0a, that means, I can reduce the wdXa disk to the minimum requirements (1 Gb for example) Christophe
