[linux-lvm] pvmove doesn't work (with either 1.0.5 or 1.1-rc2)

[Frank Joerdens]

Here's what I get:

limedes:/usr/src/LVM/1.1-rc2 # pvmove --verbose /dev/sdc1 /dev/hdd
pvmove -- checking name of source physical volume "/dev/sdc1"
pvmove -- locking logical volume manager

[1/1]
pvmove -- ERROR reading input physical volume "/dev/sdc1" (still 65536
bytes to read)
pvmove -- ERROR "pv_move_pe(): read input PV" moving physical extents

As I mentioned before, there is exactly one PE left to move in this PV:

limedes:/usr/src/LVM/1.1-rc2 # pvdisplay /dev/sdc1
--- Physical volume ---
PV Name               /dev/sdc1
VG Name               funkadelic
PV Size               30.64 GB [64259937 secs] / NOT usable 944 KB [LVM:
151 KB]
PV#                   1
PV Status             available
Allocatable           yes
Cur LV                1
PE Size (KByte)       4096
Total PE              7844
Free PE               7843
Allocated PE          1
PV UUID               mPFcyy-wTUk-X3OI-fczK-XzHN-lkdF-nDrH3q

Any ideas?

Thanks, Frank
