[lvm-devel] [ANNOUNCE] shared snapshots for userspace

[Mikulas Patocka]

Hi

I released userspace support for shared snapshots. It can be downloaded 
from
http://people.redhat.com/mpatocka/patches/userspace/new-snapshots/lvm-2.02.53/

It allows to create, delete, activate, deactivate the shared snapshots. It 
supports resize too but the kernel doesn't (so you can resize the store 
but it has no effect).

Use --sharedstore mikulas or --sharedstore fujita-daniel parameter to 
specify the shared store type, otherwise the syntax is the same as for 
nonshared snasphots.

It creates an lvm volume with suffix -shared that represents the shared 
volume. It can never be activated (the origin is activated instead). 
Individual snapshots are then placed into this -shared volume.

The kernel patches are at
