RE: Converting Mirroring to Raid

["Art Tostaine, Jr." <art@xxxxxxxxxxx>]

Kirk:

Thanks for the replies.

We are at 92% with mirroring.

We are trying to minimize the time spent watching the system turn raid on.  Do 
you know how long we can expect that to take?

I thought that turning on Raid means the system has to make at least 25% space 
on each drive for the striping, therefore, the more
data, the longer the process.  Would love to hear that I'm wrong.
