storage controller does not support singleton wildcards

[mlosapio]

The scenario where you would want all available disks configured into a RAID is not supported.

Reproduce:

[root@master ~]# stack list storage controller  
SCOPE  ENCLOSURE ADAPTER SLOT RAIDLEVEL ARRAYID OPTIONS
global --------- ------- *    0         1       -------

This will not produce the expected results - which would be a RAID0 array with all available disks.

And this section gets skipped because it's and

The default is JBOD which is what you see in the global line. All disks essentially have no RAID. What you're asking for is a stripe across all disks, no mirroring?

[mlosapio]

Correct - stripe across all disks.

This seems to have produced the desired results.

I'm happy to push a diff if this is acceptable.

Hey @mlosapio, this required a code change deeper in the current codebase of stacki.

It's fixed now, and will be available in the next release.

Thanks for the bug report.
