What about alignment?
I know that in our friendly DM universe the volume will be aligned. But
what if the user does mkfs on /dev/sdX and the drive isn't naturally
aligned?
heh, mkfs.ext* complains if you point it at a whole disk, though it will
proceed...
How flexible is the extN on-disk format? Can you pad and shift things
if need be?
shifting by 63 sectors would be tough I think; maybe a stern warning and
a "proceed y/N?" would be better.
I had sort of assumed that -we- could assume the lower layers
(partitions, volumes) got well-aligned before mkfs, but didn't think
about making the fs on the whole device.
Also, are you guys affected by the previously-acked-sectors-are-now-gone
problems with 512-byte logical/4KB physical drives?
previously-acked-sectors-are-now-gone? I guess I haven't been keeping
up. What do you mean by this?
