Hello all,
Is anyone aware of ongoing development to provide the capability
to take a snapshot of a block device?
Thanks,
Jonathan

It's part of Linux-LVM since version 0.8 and thus part of Linux 2.4.

Of course it doesn't work. We've performed a software upgrade.

You need to get the recent LVM 0.9.1 Beta 7 software *and* to patch your
kernel as well, because that'll fix some snapshot related flaws.
