I managed to write a lilo block (lilo) to the start of a PV which I have on /dev/sda (note, /dev/sda is a whole disk PV, unpartitioned). However, looking at a number of different PVs here, it appears that the LVM data starts at 0x200 with: "LABELONE". i.e.: # hexdump -C /dev/sdc3 00000000 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 00000200 4c 41 42 45 4c 4f 4e 45 01 00 00 00 00 00 00 00 |LABELONE........| ... # hexdump -C /dev/sdb 00000000 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 000001b0 00 00 00 00 00 00 00 00 dc 59 0f 10 cf c9 00 00 |.........Y......| 000001c0 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 00000200 4c 41 42 45 4c 4f 4e 45 01 00 00 00 00 00 00 00 |LABELONE........| ... # hexdump -C /dev/sda 00000000 fa eb 31 12 00 00 4c 49 4c 4f 16 08 10 00 01 00 |..1...LILO......| ... 00000180 30 e4 cd 13 eb 91 e8 93 fe 44 69 73 6b 20 72 65 |0........Disk re| 00000190 61 64 20 65 72 72 6f 72 0d 0a 00 00 00 00 00 00 |ad error........| 000001a0 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| 000001b0 00 00 00 00 00 00 00 00 c6 08 1a 45 cf c9 00 00 |...........E....| 000001c0 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 000001f0 00 00 00 00 00 00 00 00 00 00 00 00 00 00 55 aa |..............U.| 00000200 4c 41 42 45 4c 4f 4e 45 01 00 00 00 00 00 00 00 |LABELONE........| Is that correct? Is there anything I should do to repair this or is my brainfart benign to this PV? Thanx! b.
