Good morning,
We are dealing with the following status:
~> sudo sgdisk -p /dev/sda
Disk /dev/sda: 60538881 sectors, 28.9 GiB
Model: DataTraveler 3.0
Sector size (logical/physical): 512/512 bytes
Disk identifier (GUID): DB25F93B-B36F-46DE-A10D-D5D5BA500CE8
Partition table holds up to 128 entries
Main partition table begins at sector 8192 and ends at sector 8223
First usable sector is 8224, last usable sector is 60530657
Partitions will be aligned on 8-sector boundaries
Total free space is 57902538 sectors (27.6 GiB)
Number Start (sector) End (sector) Size Code Name
1 16384 59979 21.3 MiB 0700 boot
2 65536 114831 24.1 MiB 0700 bootfs_A
3 122880 988179 422.5 MiB 8300 rootfs_A
4 991232 1040527 24.1 MiB 0700 bootfs_B
5 1048576 1913875 422.5 MiB 8300 rootfs_B
6 1913880 2254665 166.4 MiB 8300 datafs
7 2254672 2595457 166.4 MiB 8300 varfs
8 2595464 2660999 32.0 MiB 8300 appfs
As you can see, we have GPT not at the beginning of the disk, but we have relocated it at sector 8192
(architectural needs). We need to resize appfs partition to take all free space. So:
~> sudo
parted /dev/sda
GNU Parted 3.4
Using /dev/sda
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) resizepart
Warning: Not all of the space available to /dev/sda appears to be used, you can fix the GPT to use all of
the space (an extra 8190 blocks) or continue with the current setting?
Fix/Ignore? Ignore
Partition number? 8
End? [1362MB]? 100%
(parted) q
Information: You may need to update /etc/fstab.
~> sudo
sgdisk -p /dev/sda
Disk /dev/sda: 60538881 sectors, 28.9 GiB

Disk identifier (GUID): DB25F93B-B36F-46DE-A10D-D5D5BA500CE8
Partition table holds up to 128 entries
Main partition table begins at sector 2 and ends at sector 33
First usable sector is 8224, last usable sector is 60530657

8 2595464 60530657 27.6 GiB 8300 appfs
As you can see, the partition has correctly been resized, but the partition table has been relocated
at sector 2. I am expecting the resizepart command would update the current GPT information without moving it.
Thank you all in advice
Best regards,
