Use logical partition to create configdrive if no more primary partitions could be created

[Shivanand Tendulker]

When primary partitions are not available, Ironic should check if configdrive partition could be created as a logical partition.

The disk could have 3 primary partitions and 1 extended one which would allow you to create the config drive as a logical partition.
So the 4 partitions thing only is a blocker if they are 4 primary partitions

Want to confirm your case first:

1. Your images have 4 primary partitions already
2. Run ironic to deploy the image to baremetal
3. IPA run out of error which can not add configdrive partition

Correct me if my understanding is wrong.

[Haomeng,Wang (whaom)]

And can you provide more details, such as which driver are you using and how the images do you create?

[Haomeng,Wang (whaom)]

And can you help to check your image partitions with below command, and paste the result here for investigation to see if it is MBR or GPT ?

# gdisk -l <img>

I also can't quite understand this bug.. Ironic is expected to wipe the partition table, so you can't really have so many partitions there..

Also why not use GPT?

[Shivanand Tendulker (stendulker)]

This was for the BIOS only whole disk image, so cannot replace it with GPT. This defect was raised wrt Lucas's comment. I think nobody has hit it, but a possible scenario.

We do this on the GPT path, and that is the default path at this point. Marking fix released.
