I have a logical volume mirrored between /dev/mapper/mpath0 and /dev/mapper/mpath3: # lvs -a -o +devices LV VG Attr LSize Pool Origin Data% Move Log Copy% Convert Devices vm01-disk VMMIRROR mwi-aom- 7.00g 100.00 vm01-disk_mimage_0(0),vm01-disk_mimage_1(0) [vm01-disk_mimage_0] VMMIRROR iwi-aom- 7.00g /dev/mapper/mpath3(0) [vm01-disk_mimage_1] VMMIRROR iwi-aom- 7.00g /dev/mapper/mpath0(0) The master device (/dev/mapper/mpath0) failed and i repair it without any problem, but now my master device is /dev/mapper/mpath3. I want to change my master device back to /dev/mapper/mpath0 again. How can i do this?
