Still no luck - gpt refuse any form of cooperation, all operations
(remove, migrate, show) gave me simply:
'gpt: error: bogus map'
Finally I found some suggestions: http://markmail.org/message/efyk7bbzvssidvl5
- looks like I got mix of GPT and MBR partitions:
# gpt -vvv show ld0
gpt: rld0d: mediasize=145458462720; sectorsize=512; blocks=284098560
gpt: rld0d: MBR at sector 0
gpt: rld0d: MBR part: type=169, start=63, size=284098497
gpt: rld0d: Pri GPT at sector 1
gpt: rld0d: GPT partition: type=83bd6b9d-7f41-11dc-be0b-001560b84f0f,
gpt: error: bogus map
gpt: unable to open device 'rld0d': Undefined error: 0
The quickest solution for me is simply clearing disk and re-installing system,
(it isn't a problem for me) but - IMVHO - this case should be covered in
notes (or, better, at installer level - at least as BIG warning in
menu "Warning: GPT partition is already present..." etc).
