error moving last PE away

Hi

# pvmove   -v   /dev/hda10  /dev/hda8
...
pvmove -- /dev/hda10 [PE 999 [lvol5 [LE 1365]] -> /dev/hda8 [PE 560] [1/1]
pvmove -- ERROR reading input physical volume "/dev/hda10" (still 65536
bytes to read)
pvmove -- ERROR "pv_move_pe(): read input PV" pv_move_pe
pvmove -- ERROR "pv_move_pe(): read input PV" moving physical extents

I wanted to release this partition from the LVM to use it with another OS. The error once occured in June 2001 but I couldn't find a solution in the archives.

Any ideas? More infos below.

bye,

A friend gave me the hint to enlarge the partition by one block. It helped, after rebooting to let the kernel reload the partition table, pvmove ran successfully.

The partition in question looked like:

$ LC_ALL=C fdisk -l

Christian,

you are probably suffering from a misalignment bug introduced in the LVM 0.9.1 Beta series :-(

Send "pvdisplay -v /dev/hda10" output to me ([email protected]) to check this.
