Short-time lurker, first-time poster.
I have to say that I've found the forum extremely helpful for my journey into DIY NAS solutions. Unfortunately, I have reached a point that I cannot overcome. I've searched the forum and the almighty Google but have not been able to find an answer to my problem. So here it goes...
I have a Dell T310 (X3430, 24 GB RAM, 3 x 4TB Seagate SAS drives connected to an SPL-3 HBA).
1.) I have installed OMV 5.3.4-1 and am using unionfs with SnapRAID.
2.) I went through the process of adding the two disks to a pool in unionfs and then added those disks as data disks in SnapRAID.
3.) I moved my data to the pool, which is approximately 4.7TB of data.
4.) After I was done migrating the data, I added a parity disk in SnapRAID.
Now, here's the problem. I selected the "Sync" option in SnapRAID to start the initial sync process and I am seeing speeds of 53 MB/s. No fluctuations, just 53 MB/s. The fact that it isn't fluctuating at all, makes me think there's some kind of bottleneck, however, I can't determine where. The drives seem to transfer at around 112 MB/s over my network without issue.
