hi there, I have a Gigabyte GA-7ZXR with the onboard Promise IDE ATA100 RAID Controller (supports RAID 0 and 1, single / mixed). I installed FreeBSD 4.2 release on a RAID 1 (mirroring) and rebooted. No problems so far. But when I power off and remove one disk, FreeBSD stops while booting missing /dev/ar0 (I installed on /dev/ar0s1a, b, e, f -> RAID Array) with the following message: can't stat /dev/ar0s1a: No such file or directory any ideas? On the other side, while installing / partitioning the disk I had /dev/ad4 and /dev/ad6 as options too for partitioning, not only /dev/ar0 ...?? This makes me wondering, does FreeBSD see them as an Array and additionally as 2 single disks? When i think about this, does FreeBSD recongnise a broken Array as a 'standalone disk' (no array, just the disk itself) instead 'this disk is part of array which is just not complete'..? when using mirroring, this shouldn't be handled this way, i think. in my opinion mirroring means, the still systems runs, even with only one disk. or am i wrong? maybe at the time 4.2 was released, there was no support for booting a broken mirrored array. if it's now, then please tell and forgive me :) I was looking for documentation for this Promise Controller under FreeBSD but didn't find something usefull about support of Arrays under FreeBSD (stripe / mirror), that's why i ask you. hope you can help me, thanks in advance. if you need more informations, tell me. alex To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
