I've posted a question to the debian-user mailing list, but am yet to receive a
response.
I am running Debian 7.9 64-bit with kernel version 3.2.0 and would like to use
the 'lvconvert --merge' feature, but do not have 'snapshot-merge' support in
the kernel. Does anyone have any idea how to enable this?
The original post is here:
https://lists.debian.org/debian-user/2016/05/msg00496.html.
So you don't have any snapshot support in your running kernel.
But your kernel is modular, and if you attempt a snapshot operation,
lvm2 will try to load the snapshot module if it is available.
To try this manually, do 'modprobe dm-snapshot' (see 'man modprobe')
then retry 'dmsetup targets'.
Please always attach version of lvm2 and kernel in use.
Debian version has some local patches for 'modprobe' usage - so maybe check
it 'auto' modprobe works properly in your case ?
(rmmod dm-snapshot - and check if lvcreate -s still works)
Are you build your own kernel - or do you use 'distro' debian kernel ?
