Comment 2 for bug 1813228

Curtin generally expects vgchange -ay to exit with 0, non-zero exit indicates as failure.

In this install[1], multipath is installed and when it is present, vgchange detects that
the lvm devices it found were created using device names that were not multipath names.

It is not yet clear whether this is fatal to curtin. Curtin probes the LVM subsystem
to discover any LVM devices present; at this early stage, it is possible that *none* of
the devices discovered will be related to the storage config sent to curtin, and curtin
should then ignore all of these devices.

This approach argues for curtin it ignore the error return code, and possible not even log
the warning/error from vgchange -ay.

On the counter side, if a node is able to detect multiple paths to devices and potentially
discovers misconfiguration, it may not be prudent to continue; if any of the devices in storage config are part of the detected LVM devices.
