Package: gdisk
Version: 0.8.5-1
I am trying to create 3 partitions on a 7.5 TiB RAID60 device (/dev/sda,
handed to the OS by a hardware raid controller).
Status before:
---
% sgdisk -p /dev/sda
Creating new GPT entries.
Disk /dev/sda: 16002748592 sectors, 7.5 TiB
Logical sector size: 512 bytes
Disk identifier (GUID): F6924DB1-0783-4AC2-8499-EBA2F951CE07
Partition table holds up to 128 entries
First usable sector is 34, last usable sector is 16002748558
Partitions will be aligned on 2048-sector boundaries
Total free space is 16002748525 sectors (7.5 TiB)
Number Start (sector) End (sector) Size Code Name
---
Creating the first two partitions succeeds:
---
% sgdisk -p /dev/sda
Disk /dev/sda: 16002748592 sectors, 7.5 TiB
Logical sector size: 512 bytes
Disk identifier (GUID): 12C31C64-F48E-4D2B-AE58-FE34289BE587
Partition table holds up to 128 entries
First usable sector is 34, last usable sector is 16002748558
Partitions will be aligned on 2048-sector boundaries
Total free space is 16002209899 sectors (7.5 TiB)
Number Start (sector) End (sector) Size Code Name
1 2048 20480 9.0 MiB 8300
2 22528 542720 254.0 MiB 8300
---
However, trying to create a third one that contains the remaining space
fails:
---
% sgdisk -g --new=3:266M:16002748558 /dev/sda
Could not create partition 3 from 544768 to 32773629046784
Error encountered; not saving changes
---
Strangely, 32773629046784 is the sector I specified multiplied with the
current sector-alignment (2048).
Specifying "0" for the start sector will make it work, though.
---
% sgdisk -g --new=3:0:16002748558 /dev/sda
Information: Moved requested sector from 542721 to 544768 in
order to align on 2048-sector boundaries.
The operation has completed successfully.

I'm on Debian 7.0, amd64.
Greetings.

According to my tests, this bug exists in jessie (gdisk 0.8.10-2)
but was fixed in stretch (gdisk 1.0.1-1). Therefore closing. The
test script is attached.
