Hello everyone - I apologize if this is a question for elsewhere, please let me know if it needs to be moved.
We recently had a Thecus n7700pro get the corrupted DOM and get stuck on "Self Testing..." screen. This is a 7-Drive, RAID 6 setup, each disk being a WD RED witth 3TB, giving us roughly ~15TB usable space, ~13TB used.
So, I took out all of the hard drives, and plugged them all into my old-ish gaming PC (AMD-8350, Sabertooth 990FX R2, 16GB RAM), and installed Unbuntu onto the system on an 8th drive (this fills up my SATA slots on the board).
I was following a tutorial on a thecus thread, and installed mdadm along with lvm, and after reboot and plugging in all 7 drives, I can see my RAID array and access the data.
I am now attempting to transfer files over onto an external, USB 3.0 6TB Harddrive in chunks, and migrate them onto the new NAS that will be arriving shortly (8-bay synology with 8x6TB IronWolf's). The problem is, my transfer speeds are insanely slow. I am getting around ~500KB/s to 1.2MB/s, causing a 230GB transfer to be estimated at around ~100 hours.
Are there any suggestions on how to potentially help speed this up? I've gone into the BIOS, and I've made sure USB 3 is enabled, I've also gone in and turned on IOMMU along with EHCI. And, when copying files that are not on the RAID array, i do get closer to 50MB/s transfer speeds, so my fear is that I'm just at the limit of what the board can handle.
As always, really appreciate any suggestions or help on this.
Thanks!
