17:05 UTC in reply to "RE[3]: RAID Z" Member since:  As I said
in another post, if I can take a soft-RAID5 array (E.g. on-board
controllers) that was built under Windows and move it to Linux
and back, its standard.  Yes, but that's only if you use a file
system that both operating systems can read and the controller
is recognized by both operating systems. It's only possible
because the controller abstracts the array in to a logical
volume that the PC can see -- not because it's a "standard" RAID
configuration. The user land portion of the operating systems
doesn't care about anything but the file system. The OS kernel
and drivers take care of the hardware abstraction layer so if
both platforms don't have drivers for your controller's chipset
or can't read the file system format then you're out of luck. I
don't see how any of this makes portability between operating
systems easier merely because you chose a RAID. I could use
fibre channel or iSCSI to
