Is pvmove supposed to work on a 2.6.0-test9 kernel? When I try to
clear a physical volume, I get the message:
device-mapper ioctl cmd 9 failed: Invalid argument
The kernel is compiled with CONFIG_DM_IOCTL_V4, and I'm using
lvm2-2.00.06-1. You should be able to reproduce this error with the
following script:
--------------------------------------------------
#!/bin/sh -x
dd bs=1024k count=20 if=/dev/zero of=/tmp/image1
dd bs=1024k count=20 if=/dev/zero of=/tmp/image2
losetup /dev/loop1 /tmp/image1
losetup /dev/loop2 /tmp/image2
pvcreate /dev/loop[12]
vgcreate -s 1 test /dev/loop[12]
lvcreate -L 8 -n a test
lvcreate -L 8 -n b test
lvcreate -L 8 -n c test
lvremove -f /dev/test/a
lvremove -f /dev/test/b
# this fails:
pvmove -v /dev/loop2
pvmove --abort
lvremove -f /dev/test/c
vgremove test
pvremove /dev/loop[12]
losetup -d /dev/loop2
losetup -d /dev/loop1
rm -f /tmp/image[12]
--------------------------------------------------
The output from the first pvmove command is:
+ pvmove -v /dev/loop2
device-mapper ioctl cmd 9 failed: Invalid argument
Couldn't load device 'test-pvmove0'.
ABORTING: Temporary mirror activation failed.
device-mapper ioctl cmd 9 failed: Invalid argument
Couldn't load device 'test-c'.
