Ein Test:
Ausgangslage:
=============
1 Sata-Platte.
sata # lilo -T vol-ID
BIOS Volume ID
0x80 56D16105
Volume ID's are all unique.
sata #
Einbau einer 2. leeren Sata-Platte:
===================================
sata # lilo -T vol-ID
BIOS Volume ID
0x80 56D16105
0x81 00000000 -
Volume ID's are all unique.
'-' marks an invalid Volume ID which will be automatically updated
the next time /sbin/lilo is executed.
Clonen der 1. Sata-Platte auf die 2. Sata-Platte:
=================================================
Die erste Sata-Platte ist GPT-partitioniert.
sata # sgdisk -R=/dev/sdb /dev/sda
The operation has completed successfully.
sata # sgdisk -p /dev/sda
Disk /dev/sda: 8388608 sectors, 4.0 GiB
Logical sector size: 512 bytes
Disk identifier (GUID): 9E0003A7-B75C-418E-B288-0BF52B51211D
Partition table holds up to 128 entries
First usable sector is 34, last usable sector is 8388574
Partitions will be aligned on 2048-sector boundaries
Total free space is 22494 sectors (11.0 MiB)
Number Start (sector) End (sector) Size Code Name
1 2048 100351 48.0 MiB 8300 boot
2 100352 362495 128.0 MiB 8200 swap
3 362496 8368094 3.8 GiB 8300 root
sata # sgdisk -p /dev/sdb
Disk /dev/sdb: 8388608 sectors, 4.0 GiB
Logical sector size: 512 bytes
Disk identifier (GUID): 9E0003A7-B75C-418E-B288-0BF52B51211D
Partition table holds up to 128 entries
First usable sector is 34, last usable sector is 8388574

2 100352 362495 128.0 MiB 8200 swap
3 362496 8368094 3.8 GiB 8300 root
Wie man hier schön sieht, ist die GUID der Platten identisch.
sata # lilo -T vol-ID
BIOS Volume ID
0x80 56D16105
0x81 00000000 -
Volume ID's are all unique.
'-' marks an invalid Volume ID which will be automatically updated
the next time /sbin/lilo is executed.

Um die GUID einzigartig zu machen:
sata # sgdisk -G /dev/sdb
The operation has completed successfully.
