Hi, I just noticed this message today, and there's one thing I don't understand ... Fernan Aguero wrote: > I'm trying to set up two disks to contain both gmirrored and > gstriped slices. > > This is what I'm trying to achieve: > adxs1, swap > adxs2, gmirror > adxs3, gstripe Can someone please explain why such a setup makes sense? As far as I can tell, the purpose of gmirror is to provide redundancy in the case of drive failure. I.e. if one drive fails, the system keeps running happily instead of crashing. But if only part of the disk is mirrored, then the system will still crash if one drive fails. So what is the point of using gmirror, if not on whole disks? Just wondering.
