Hi, Interesting problem. I'm setting up an all software RAID system and after a few fits and starts have reached some success. I started to do some testing and have run into a problem. What I was doing is I was one by one unplugging one of the SCSI drives and then powering up the system to make sure it would power up properly. The first time I did this everything worked great. I plugged the drive back up and used raidhotadd to recover and got everything to UUU. I then powered off and unplugged another drive, system boots up great with only two drives. Now its time to plug the drive back in and rebuild the array to be ready to unplug the last of the three drives for a thorough test. Only, now I can ONLY boot up if I DO NOT have the missing drive plugged in. This is really weird. If I have all three devices attached then it claims that 2/3 of the devices that make up md2 (my root) are unavailable and well then we are screwed. WTF? Anyway, here's my setup, let me know what else you need to know: /boot /dev/md0 RAID1 (/dev/sda1 /dev/sdb1 /dev/sdc1) swap /dev/md1 RAID1 (/dev/sda2 /dev/sdb2 /dev/sdc2) / /dev/md2 RAID5 (/dev/sda3 /dev/sdb3 /dev/sdc3) /home /dev/md3 RAID5 (/dev/sda5 /dev/sdb5 /dev/sdc5) /var /dev/md4 RAID5 (/dev/sda6 /dev/sdb6 /dev/sdc6) The drive that is currently "failed" is /dev/sdb. Again, the system boots up happily with sdb disconnected. But has fits if it is reconnected and all 3 drives are connected.
