Target

build a RAID with 3 Disks, add some Data, destroy one Disk, and rebuild the Raid (and it’s Data).

Requirements

  • OpenBSD 7.2 Running
  • added 3 Disk with 20G each: sd0, sd1, sd2

Find Disks

root@puffy # dmesg |grep -i sec

wd0: 64-sector PIO, LBA, 20480MB, 41943040 sectors
sd0: 20480MB, 512 bytes/sector, 41943040 sectors
sd1: 20480MB, 512 bytes/sector, 41943040 sectors
sd2: 20480MB, 512 bytes/sector, 41943040 sectors

sd0, sd1, sd2 are New Disks for RAID
