I'm seeing a strange problem when partitioning disks for some new
machines we recently purchased. We have previously not had any
problems with machines of the same model, the only difference with the
latest version is a different brand of SSD (older have SSSTC, new are
Samsung), the disks are the same capacity.

Here's the error from parted:

Executing: parted -s /dev/nvme0n1 mkpart '" "' "" 16602181633B 46602178560B
parted -s /dev/nvme0n1 mkpart '" "' "" 16602181633B 46602178560B had exit code 1
(STDERR) Error: You requested a partition from 16.6GB to 46.6GB (sectors 32426136..91019880).
(STDERR) The closest location we can manage is 16.6GB to 46.6GB (sectors 32426137..91019880).

Note that the first value of the range of sectors is off by 1.

I've tried changing the alignment (we normally use 4096 for SSDs),
varying the order in which the partitions are specified and varying
the sizes of the partitions, nothing helps. Attached is my
setup-storage.conf file.

I was using FAI version 6.2.3 but this also happens with version
6.4.3. Can anyone suggest anything else I can try or where I should
start poking to hunt for a bug?


Thanks,

Stephen Quinney
