[parted-devel] [PATCH 0/3] Rework parted-print, make it more useful with empty disk.

[Petr Uzel]

'parted print $dev' does not give any useful information for a device without a
disk label, even the informations which are not dependent on the label
(geometry, size, sector size etc.). This is an attempt to make 'parted print'
more useful with an empty disk.

This series is based on feedback I got for the first 'always print geometry'
patches:

Before:

modprobe scsi_debug
./parted -s /dev/sdd print
   Error: /dev/sdd: unrecognised disk label

After:

./parted -s /dev/sdd print
  Error: /dev/sdd: unrecognised disk label
  Model: Linux scsi_debug (scsi)
  Disk /dev/sdd: 8389kB
  Sector size (logical/physical): 512B/512B
  Partition Table: unknown

I would like to suppress the 'Error: /dev/sdX: unrecognised disk label" in the
output, but I don't know how to achieve that. I know I could catch the
exceptions (ped_exception_fetch_all()) from ped_disk_new(), but this in turn
disables some other error messages from ped_disk_new(), that should not be
suppressed, e.g. the 'Error: The primary GPT table is corrupt, but the backup
appears OK'. Any idea how to suppress this particular error message only when
called from do_print?

Thanks,

	Petr
