I'm testing ProxmoxVE 1.5 and few months ago everything was perfect.
Now suspend backup still working, but snapshot not :(
Here is log:

vzdump --quiet --snapshot --compress --storage backup --mailto xxx@xxxxx 107

ext-fs error are quite normal for snapshots, but usually they are automatically resolved. Maybe it helps when you run fsck on the data partition (simply reboot the server)?
