Bug#614632: Disk partitions not created along cylinder boundaries
Quoting Colin Watson <cjwatson@debian.org>:
This is entirely intentional. No remotely modern disk requires
partitions to be aligned on cylinder boundaries, and cylinder alignment
is very bad indeed for performance on many modern disks ...
That's good to hear! I was concerned, because fdisk does not show this
"non-problem" on any of the older systems that I have running
currently and I did not want to run into any performance problems
later on.
You have not described why cylinder alignment was bad for you, aside
from the bogus error message from fdisk (use the -c option to turn this
off). Did anything actually go wrong?
No, nothing else seemed to be wrong. I was suspected there might be a
(small) performance penalty, but never actually noticed anything.
Perhaps you were just confused by fdisk being stuck in the past?
That looks to be the case.
Yes, there may be a little more unusable space now, but it should be no
more than a megabyte - in other words, a negligibly tiny fraction of the
size of the disk.
Strange, though, that the version of the partitioner from last June
should give a different result (on the same disk) than the later ones
-- a result that fdisk does not complain about.
Oh well. It sounds like it might be helpful if this bug report was
moved to the "util-linux" package (fdisk). Can you arrange this?
Thanks very much for your explanation!
Cheers,
Jaap
