Stuck on /dev/sda
Using Hard Disk: /dev/sda
After this, the capture will not continue to the next step until enter is pressed, then you receive the message:
"Saving Partition Table (GPT)…Invalid Partition DATA!"
Or your capture never progresses past this phase:
"Saving original partition table…"
Your particular capture issue means the disk has remnants of GPT partitions on them where they’re not expected to be.
You will need to put system you’re trying to capture from in an capture-debug state.
To create a debug capture, use the web interface to capture as normal, but on the confirmation screen, check the checkbox for "Debug", and then confirm the capture. Network boot the device as you normally would. It will display some information on the screen, which you will need to press [enter] to pass through, this happens twice in 1.3.0. After this, you will be at a shell prompt. This is a Linux shell prompt.
Once at the prompt, run fixparts and accept the things it asks.
fixparts /dev/sda follow prompts to delete and then write changes with ‘w’
From there, once fixed, you can type fog and it should begin the capture process without hanging.
