Hi, unfortunately the bug is still not fixed despite the NMU; while sgdisk doesn't print errors anymore, it also doesn't actually perform the requested operations.
See e.g. # sgdisk --zap-all /dev/sda Creating new GPT entries in memory. GPT data structures destroyed! You may now partition the disk using fdisk or other utilities. Looks good, but no partition table has actually been created: # parted -s /dev/sda print Error: /dev/sda: unrecognised disk label Model: VMware Virtual disk (scsi) Disk /dev/sda: 10.7GB Sector size (logical/physical): 512B/512B Partition Table: unknown Disk Flags: So let's create a partition table with parted and verify that it's there: # parted -s /dev/sda mklabel gpt # parted -s /dev/sda print Model: VMware Virtual disk (scsi) Disk /dev/sda: 10.7GB Sector size (logical/physical): 512B/512B Partition Table: gpt Disk Flags: Number Start End Size File system Name Flags Now let's try to create a partition with sgdisk: # sgdisk --set-alignment=1 --new=1:0:4M --typecode=1:EF02 --change-name=1:grub No error message, but the partition isn't there: # parted -s /dev/sda print Model: VMware Virtual disk (scsi) Disk /dev/sda: 10.7GB Sector size (logical/physical): 512B/512B Partition Table: gpt Disk Flags: Number Start End Size File system Name Flags Best regards, András -- Money can't buy friends, but you can afford a better class of enemy.
