Hi,
I have several thumb drives and had disks. To be able to exchange the
hard disks, all devices are bootable. I have tested the setup some time
ago and it did not give me problems to boot from the external media via USB.
I will take two hard disks as an example:
=> 63 976773105 ada0 MBR (465G)
63 1953 - free - (976k)
2016 976771152 1 freebsd (465G)
=> 0 976771152 ada0s1 BSD (465G)
0 10240000 1 freebsd-ufs (4.9G)
10240000 32768000 2 freebsd-swap (15G)
43008000 10240000 4 freebsd-ufs (4.9G)
53248000 10240000 5 freebsd-ufs (4.9G)
63488000 102400000 6 freebsd-ufs (48G)
165888000 810883144 7 freebsd-ufs (386G)
976771144 8 - free - (4.0k)
=> 34 976773098 da0 GPT (465G)
34 128 1 freebsd-boot (64k)
162 6 - free - (3.0k)
168 10485760 2 freebsd-ufs (5.0G)
10485928 33554432 3 freebsd-swap (16G)
44040360 10485760 4 freebsd-ufs (5.0G)
54526120 10485760 5 freebsd-ufs (5.0G)
65011880 104857600 6 freebsd-ufs (50G)
169869480 806903648 7 freebsd-ufs (384G)
976773128 4 - free - (2.0k)
The system started from ada0. It fails to start from da0 now.
Before I switch the disks, does anybody know of something which causes
the problem?
If this matters, I did this with an X220 ThinkPad.
