Trap

Thanks for the reply. I was wondering if I might be having issues with my cache drive, and I considering just swapping it out. I figured I'd check if it was something more simple first.

Hi all! I've been struggling with a problem with my Unraid server (currently on 6.6.6) for a while now. Basically, from a fresh power up, it works normally. I use it primarily for Plex. After a few days, I can no longer transfer any files to it (it says its read-only), and my Plex clients can no longer see the server. I can still access it via the web interface, but it no longer works until I do another reboot. I've attached the diagnostic zip here. Anyone seen this before? Thanks for the help! tower-diagnostics-20190414-1218.zip

So am I correct in reading that the only way to fix the issue with the Samsung drives is to move them to an separate SATA controller that isn't AHCI? There's nothing I could do for the onboard controllers? Did you notice any other performance hits with these drives outside of parity rebuilds/checks?

Good to know, thanks!

Thanks Benson. For some reason I didn't see your other post earlier or I would've responded to that too. Thanks for the help everyone, I appreciate it!

Not sure what you mean. I have a parity drive, its the 8tb one. Its new and in the process of a parity sync.

What should I be looking for there?

Thanks for taking the time to help!

Here are the system stats screen shots. The interesting thing is my speed is now up to ~95 mb/s now that disk 2 is in standby mode (still no errors). What do you think that means?

Ok, I'll do that and post the results shortly.

Are you talking about the Dynamix System Stats app? If so, I don't have it installed. Can I do that during the parity-sync?

Average CPU usage is less than 10%. Aren't the SATA controllers usually determined by the chipset (H97 in this case), unless there's extras put on by the manufacturer? Not sure I've ever seen a motherboard spec say anything other than SATA 6Gb/s.

Thanks for the quick replies. My motherboard is a Gigabyte H97N-WIFI. What diagnostics should I do and can I do them during the parity-sync?

I just upgraded my parity drive from a 3tb to an 8tb, and the parity-sync is running at ~30mb per second. I've read quite a few threads about what speeds should be expected, and I get the feeling this is on the low end. I have 6 drives (1 cache) all connected directly to the motherboard. There's also zero errors shown on the unraid dashboard. What's the latest consensus? Is my parity-sync going slow enough that there might be an issue?
