I'm not quite sure where to start. I have a weird issue I can't quite pin down. I'm not even sure it's a Drive Pool issue, but I have many other systems with the same setup and the only difference is Drive Pool. This is my primary system. Below are specs:
All 16 drives are pooled to a single 18.5TB E drive. I have nearly the entire drive duplicating, other then a few download and temp folders of about 90GB. I also have a folder with almost 1TB of VMware Workstation virtual machines that I use for test labs, studying, work, etc.
Now that you have an idea of my system, I'll explain my issue. The system has no issues doing multiple reads/writes to any of my standalone non-pooled drives. However, when I start more than 2 read/write jobs on the pool things grind to a hault. It seems like anytime I do more than 1 or 2 things at a time the system seems to hang. For example, I can start a VM and do a copy/read job from the E drive, but if I start anything else that accesses the E drive one of them will hang. After a few minutes one of the running jobs hangs and another picks up where it left off. While a job is hung the program goes "Not Responding" and will stay that way until it gets read/write activity again. I had this problem prior to adding the additional 8 drives and the USB3.0 external drive enclosure. I also had this issue prior to duplicating. I ended up duplicating initially thinking I could fix the problem by creating multiple read streams.
Perhaps there is a setting I'm missing, or this is a limitation of the DrivePool storage driver. Just not sure what else to test, as I've been playing around with this issue troubleshooting for almost 6 months now. Ultimately I'd like to read/write without stream/job limitations, or at least more than what I'm getting. I realize the performance implications, but I just don't want a stream/job to go completely dead and show "Not Responding" in the mean time.
