If you reside with gpart, you may hit a frustratingly stupid gpart bug.
We tell a lie about the CHS of the SD cards. This lie works its way into =
the alignment of the partitions.
The md and da devices also lie about the CHS of SD cards. They tell =
different lies (and often times
different USB adapters tell different lies) so that screws up gpart. It =
assumes that the CHS is The Truth
and The One True Way to create partitions is to have them cylinder group =
sized and aligned, even when
resizing an existing partition. However, since the CHS is a lie, and =
nobody can get their story straight,
gpart expresses its displeasure by starting the partition at a new =
location, effectively killing your
filesystem which now starts at the wrong place on the disk...
That=E2=80=99s what=E2=80=99s killing the autoresize. :( Sadly, I have =
no fix for this, but it is a problem I hit about 6-9 months
ago=E2=80=A6 I talked about the problem then, but I can=E2=80=99t recall =
if it was on a public mailing list or just private
email to part=E2=80=99s author.
