Bug#691271: lvm2: Losing data when moving LV between regular HD → SSD

I'm not sure if this should be reported against the LVM package or
against the kernel.
Today I've tried to move data between my old HD to my new SSD. I first
set issue_discards = 1 in the /etc/lvm/lvm.conf config file. I then used
pvmove to do the migration.
After the command has succeeded, I tried to mount it again, but it
failed to find a valid filesystem.
I've hopefully been able to find the backups of the old layout and
restore it. I tried again a 2nd time and it gave me the same result.
It worked perfectly when I've reverted the issue_discards setting back to 0.
 pvmove -n home /dev/sdb4 /dev/sda5
