Hi,

I'm trying to install Ubuntu Xenial using FAI. The storage setup is
failing, and emits the error message:

INTERNAL ERROR in setup-storage:
Invalid dev children entry
Please report this error to the Debian Bug Tracking System.
 at /usr/share/fai/setup-storage/Commands.pm line 1145.
        FAI::setup_partitions("PHY_/dev/sdbh") called at
/usr/share/fai/setup-storage/Commands.pm line 1405
        FAI::build_disk_commands called at /usr/sbin/setup-storage line 216

I'm attaching our disk-config file, and the output from running
setup-storage -d -D "sdbh sdbi" from inside the failed FAI (IYSWIM).

Thanks,

Matthew

Hi,

For reference, the underlying issue was that there was some stray md
metadata left on one of the devices (which I think was meaning md was
incorrectly trying to build the wrong array); deleting it with
--zero-superblock let FAI continue successfully.

While spotting that might be a bit more than you could expect from
setup-storage, I think it's error handling could be a bit more robust
(which is presumably why it said "please open a bug report" :-) )

Regards,

Matthew

I will tag this bug as a wishlist bug, since it's more about a better
error message.
