Nope, nothing at all to do with the volume manager. All it does
is deal with things like automatically mounting filesystems when they
come up, such as when a CDROM is inserted.
The issue concerns partitioning and where "data" starts on the
disk...and most importantly, whether or not that data includes the
block containing the partition table. Traditionally, the "c"
partition on a Unix system means "the whole disk" but unfortunately
(from what I've seen) that doesn't include the block containing the
partition table on some systems.
dd also seems to have some implementation-specifics
baked into it. On Solaris I was completely unable to
transfer a raw VMS disk image from one drive to
another (identical) one using dd; however the same
transfer worked correctly under Linux.
This is not dd, but the disk device
drivers underlying OS. It's probably a good thing for most
users/workloads, but mostly
Sun's volume manager just irritates me.
Same here. Edit /etc/vold.conf to make it ignore the stuff you
want it to.
