Fixed In Version: ovirt-engine-3.5.5-1
Doc Type: Bug Fix
Doc Text:
Live merge now automatically extends the base volume for instances in which a raw, preallocated disk's snapshots have been extended beyond their original disk capacity. This makes it possible for the contents of a snapshot to be merged into the base disk even when the snapshot's parent is the smaller base disk that was not extended beyond the original disk capacity.

Copying doctext from 3.6.0 bug
Comment 2 Aharon Canan 2015-10-06 12:23:39 UTC 
Verified using the following versions:
---------------------------------------
rhevm-3.5.5-0.1.el6ev.noarch - running on Rhel6.7
vdsm-4.16.27-1.el7ev.x86_64 - running on Rhel7.1

Scenario 1:
----------------
1. Create a VM with 1gb preallocated disk (probably thin as well, didn't test that) in a block-based domain.
2. Create a snapshot.
3. Extend the disk to 2gb.
4. Start the VM.
5. Delete the snapshot - Live merge works well!
