[ovirt-users] Increase the initial size of LVM snapshots to prevent VM's from freezing

Hi all, Lately, I have been encountering an issue where VMs freeze during backups. From what I can gather, this happens because some of the VMs sometimes perform large writes during the backup window and the snapshots dose not grow fast enough. I use ISCSI storage with all VM disks preallocated. Is there a configuration value I can change in order to increase the initial size of snapshots and also maybe change the watermark trigger for the expansion of snapshots? Thanks.
