[linux-lvm] Re: [RFE] lvm-1.0.3 - progress bar similar to e2fsck for pvmove

Very strange output.

1.0.4 looks like this *without* -v ...

# /sbin/LVM_BRANCH_1-0/pvmove /dev/sdc1:5871-5873 /dev/sdc1:5874-5876
pvmove -- moving physical extents in active volume group "vg00"
pvmove -- WARNING: if you lose power during the move you may need
        to restore your LVM metadata from backup!
pvmove -- do you want to continue? [y/n] y
pvmove -- 3 extents of physical volume "/dev/sdc1" successfully moved
pvmove -- this has been a test run WITHOUT any real change

... and like this *with* -v:

# /sbin/LVM_BRANCH_1-0/pvmove -v /dev/sdc1:5871-5873 /dev/sdc1:5874-5876
pvmove -- checking name of source physical volume "/dev/sdc1"

pvmove -- /dev/sdc1 [PE 5873 [u1 [LE 1663]] -> /dev/sdc1 [PE 5876] [3/3]
pvmove -- changing lvmtab
pvmove -- unlocking logical volume manager
pvmove -- 3 extents of physical volume "/dev/sdc1" successfully moved
pvmove -- this has been a test run WITHOUT any real change

Which tool version is this?
