Bug #8292
closedceph-disk prepare output not explicit on too small disk
0%
Description
While trying to use "ceph-disk prepare /dev/sdb", where /dev/sdb has only a 1Go partition,
we get this output
STDOUT: Creating new GPT entries.
Information: Moved requested sector from 34 to 2048 in
order to align on 2048-sector boundaries.
STDERR: INFO:ceph-disk:Will colocate journal with data on /dev/sdb
Could not create partition 2 from 34 to 10485760
Unable to set partition 2's name to 'ceph journal'!
Could not change partition 2's type code to 45b0969e-9b03-4f30-b4c6-b4b80ceff106!
Error encountered; not saving changes.
ceph-disk: Error: Command '['/sbin/sgdisk', '--new=2:0:5120M', '--change-name=2:ceph journal', '--partition-guid=2:1f827f05-0ab6-442b-8a87-6158edefc304', '--typecode=2:45b0969e-9b03-4f30-b4c6-b4b80ceff106', '--mbrtogpt', '--', '/dev/sdb']' returned non-zero exit status 4
This is not really explicit and we don't get to see what's wrong.

This is going to be tricky.
I have a working solution, with nice/informational output, but the calls keep going and the execution does not halt, so
even though it is raising an error, later on it says the operation has completed successfully.
