(Re)building a RAID 1 array on the fly

[Gabriel Ambuehl]

Hi,
I was wondering about the correct procedure to (re)build a Highpoint
370 (i.e. using ata(4) based RAID array while the server is running.
I obviously can't take a production machine down for the 2hours it takes
to initialize the RAID in the BIOS and I don't want to risk losing any
data there, either.

Any pointers would be very much appreciated.

Regards,
Gabriel
