If you apply the "read block from disk" method to a RAID1 array, how you do you know whether you mean:
1) An active disk in the array 2) The actual array itself.
Hint: With Raid 1, the disks are complete images of each other. You can mount a single disk which is/was part of a raid 1 array and read all data off it.
If someone thinks about going down this road, make sure you check the multiple-device arrays BEFORE the physical disks! _____ |_____| ------------------------------------------------- ---+---+- | | Russell King rmk@arm.linux.org.uk --- --- | | | | http://www.arm.linux.org.uk/personal/aboutme.html / / | | +-+-+ --- -+- / | THE developer of ARM Linux |+| /|\ / | | | --- | +-+-+ ------------------------------------------------- /\\\ | - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org Please read the FAQ at http://www.tux.org/lkml/
