Parted and fdisk both produce bad labels as far as Solaris is
concerned. However, I think I just potted the problem. The same sort
of disk in another machine running Solaris reports:
Volume name = < >
ascii name = <SUN36G cyl 24620 alt 2 hd 27 sec 107>
pcyl = 24622
ncyl = 24620
acyl = 2
nhead = 27
nsect = 107
whereas the fdisk-created one has
Disk /dev/sda (Sun disk label): 27 heads, 107 sectors, 10025 rpm
24622 cylinders, 2 alternate cylinders, 24624 physical cylinders
i.e. it seems to be confusing cylinders and physical cylinders. I'm
not sure whether parted chose these or whether I was confused in
copying them from the Solaris version when I re-labelled. However,
the disk was originally running Solaris and got trashed by the
installer when I added the linux partitions.
The fdisk `c' and `y' commands don't actually work to change these.
`p' shows new values, but `w' doesn't actually save them.
Can anyone say if any of this is a bug that should be reported?
