https://gerrit.ovirt.org/#/q/topic:live-merge-no-raw-extension shows the patches are merged for 3.5, 3.6, and master. These patches will prevent the base raw image from growing beyond its capacity. Unfortunately for people who have experienced this problem a manual intervention will be required to lvreduce the affected base raw volume(s). This patch is included in the 3.6.3 branch, setting target milestone accordingly. (In reply to Allon Mureinik from comment #5) > This patch is included in the 3.6.3 branch, setting target milestone > accordingly. Arg, no, it isn't, but it must be, as this fix was delivered in 3.5.8. "low level image copy failed.." after executing the following steps: 1. Create VM (preallocated disk over ISCSI SD) 2. Create 2 snapshots 3. Live merge one of the snapshots 4. Clone a VM from the snapshot left Clone VM operation falied. 5fe78e7a-40d4-45d6-924e-6b5a746603b7::ERROR::2016-02-25 11:44:21,258::task::866::Storage.TaskManager.Task::(_setError) Task=`5fe78e7a-40d4-45d6-924e-6b5a746603b7`::Unexpected error Traceback (most recent call last): File "/usr/share/vdsm/storage/task.py", line 873, in _run return fn(*args, **kargs) File "/usr/share/vdsm/storage/task.py", line 332, in run return self.cmd(*self.argslist, **self.argsdict) File "/usr/share/vdsm/storage/securable.py", line 77, in wrapper return method(self, *args, **kwargs) File "/usr/share/vdsm/storage/sp.py", line 1570, in copyImage postZero, force) File "/usr/share/vdsm/storage/image.py", line 866, in copyCollapsed raise se.CopyImageError(str(e)) CopyImageError: low level Image copy failed: ("ecode=1, stdout=[], stderr=['qemu-img: /rhev/data-center/mnt/blockSD/8fc9541e-e584-4f9c-a626-f217162eafc5/images/7a4b7fa4-d739-43d6-8908-5b 6558b8d4c0/5ab11d88-04a3-4993-808d-493d6ddcfdcc: error while converting raw: Device is too small'], message=None",) ====================================================================== Used: vdsm-4.17.21-0.el7ev.noarch rhevm-3.6.3.2-0.1.el6.noarch Logs will be attached Sorry, my mistake, the build I tested with is from Feb 17.
