Local rsync job stopping midway through

[NewAtOCing]

Alright, so here is the jest of what is going on.

I have 2 volumes, MediaDrive and BackupDrive. MediaDrive is scheduled to Rsync to BackupDrive nightly, which has been working just fine. MediaDrive consisted of 3x 1TB drives in RAID5. I needed extra space so I deleted MediaDrive and recreated it as RAID0.

Once done, I went to the shell an started an Rsync from BackupDrive to MediaDrive, code is below.

rsync -av /mnt/BackupDrive/FreeNAS /mnt/MediaDrive
Side note: MediaDrive was called FreeNAS originally

So everything is going well, transferring files at ~145MB/s, then at 151GB it just stops. I rebooted, retyped the command in the shell, everything... nothing works. It seems to me like it just hits a brickwall and decided to just quit.

Relevant Info:
Using 8.3.0 Beta 3
Drive permissions on both are set to Root/Wheel w/ all privileges
FreeNAS indicates drives are healthy
Using ZFS 28 on both
Rsync service is enabled (does that matter??)
Plenty of storage space available
Using RAID-Z for BackupDrive, RAID0 for Media Drive
System has 8GB of RAM and i5-2100 processor

Any ideas would be greatly appreciated!
