hypothetically: How do I recover a software RAID 1?
It was easy to install it, using 10.3 installer. But what do I have to
do if something happens? Let's say one of two harddiscs is broken. OK,
I turn the computer off, change the broken harddisc to a working one.
And THEN? What do I have to do now? How do I get the mirrored data to
the new disc?
Basically, repartition the new disk, and add the partitions to the raid
array.
Is there something like a primary and a secondary disc? Is there a
difference which harddisc dies?
To the raid, no.
Could the system keep running if I just remove the damaged disc?
Yep, it could, provided it can boot. The array would work in degraded
mode, and of course, if that disk goes bad too then you are hosed.
Does the installer have a option for recovering RAID?
I don't think so. I haven't seen it.
Any good documentation about RAID 1 known?
