disks stage failure without visible error #1687

Bug

We justed tried to update Fedora CoreOS from 37.20230218.3.0 to 38.20230709.3.0 but now the VM fails to boot when any additional virtual disk is to be mounted. What particular bad about this, is that no more concrete error appears to be printed in the output that would allow to further track this down:

Operating System Version

Fedora CoreOS 38.20230709.3.0

Ignition Version

2.15.0

But also tested with Fedora Core OS 38.20230722.2.1 including ignition 2.16.2 with the same result.

Environment

Running CoreOS as .ova VM template on ESXi / vSphere

Expected Behavior

The VM successfully boots.

Actual Behavior

Ignition fails during boot causting the VM to enter the emergency mode.

Running journalctl -u ignition-disks.service on the emergency shell showed the actual error - mkfs.xfs failed because the disk to be formatted was less than 300MB in size. Seems like a lower limit has been introduced for xfs in one of the last releases.

I'm not sure if this is a problem with ignition but any hint about why that message did not occur within VM logs?
