Hi all,
I'm investigating atacontrol raid as an alternative to vinum.
So far it has worked great.
That's until I unplugged one of the array members.
The system boots up fine from the second disk,
but the problem ... I can't get atacontrol to rebuild the mirror onto the disk
that was removed.
I have tried every command on the atacontrol man page, but to no avail.
OS : FreeBSD 4.10
System : P3
IDE controller : Intel ICH2 ATA100 controller
and 2 x 40 GB disks.
On FreeBSD 5 atacontrol has an additional command "addspare" that I have used
with success to
add a disk to a RAID1 array and rebuild it.
Now that you know some of the details,
here are the questions
1.. How "safe" is the atacontrol raid feature?
2.. How do I rebuild an atacontrol RAID1 array on FreeBSD 4.10?
Any help would be appreciated, I have been at it the whole day!
Regards
