I have found a bug - I am just not sure whether it is
a bug in partprobe or it originates somewhere else.
I encrypted a (removable) hard drive with the intention
of putting zfs storage pools on it:
# cryptsetup -v luksFormat /dev/sdx
# cryptsetup open /dev/sdx disk
Then I created partitions for the hard drive using gdisk.
[...]
Command (? for help): p
Disk /dev/mapper/disk: 732566133 sectors, 2.7 TiB
Logical sector size: 4096 bytes
Disk identifier (GUID): xxxxxxxxxxxxx-xxxx-xxxx-xxxxxxxxxxxx
Partition table holds up to 128 entries
First usable sector is 6, last usable sector is 732566127
Partitions will be aligned on 256-sector boundaries
Total free space is 250 sectors (1000.0 KiB)

Removed (unplugged), reinserted, remounted, and unlocked the hard drive.
None of the partitions showed up initially.

So I ran partprobe to request that partition tables be re-read:
# partprobe
And only got the first sixteen partitions on the disk.

I am also wondering if the entries in /dev/mapper should just
be links to /dev/dm-nn (as the entry for the entire disk is), but
that is more of a secondary issue.
The first sixteen partitions are set up correctly.

Would appreciate your thoughts and help.
