  1. Reporting back. Now reverted to V6.6.7 and everything works again. Much quicker transfers and the cache drive is behaving correctly.
  2. Add me to the list with the exact same issues. Tried to copy a 50 GB VM img file to the SSD cache disk today and it took nearly an hour! During that time processor usage spiked to over 90% (twin Xeon with 16 cores and 128GB of RAM so resources shouldn't be an isssue...). Copying seemed to run in cycles with 1GB transferring relatively quickly with less than 50% processor usage, then a minute or so of almost stationary transfer speed with the processor spiking up to 90% +. If it's relevant, the same as @BiGs above I run a two parity disk array with two ssd disks in a cache pool. I'd noticed things were slow in the last few weeks, but hadn't connected the dots. This large file transfer was so painful I came to the forum and found this thread. Describes my issue perfectly. Going to revert to 6.6.7 and hope that fixes things. Unfortunately it seems there's a fundamental file handling issue with 6.7. Limetech haven't responded to this thread at all. In the possibly related SQLite thread they said they couldn't duplicate that problem. I haven't experienced the SQLite issue either, so I'm hoping they can duplicate this manifestation instead. I understand they are a small company, but it would be really helpful if they were to do so and acknowledge the issue (or explain why they can't). PS - The 'Minor' label on this thread is an understatement. This is way worse than a minor irritation.
  3. Final update. That seems to have solved the problems I was having with both one of my SSD cache drives, and the array drive. No problems with preclear or parity check this time. The underlying issue is, of course, the poor Marvell SATA ports. I knew about that problem, and thought I had dodg d that bullet, but hadn’t realized that the board layout is not as you might expect. The four SATA ports on their own are NOT the 4 Marvell ports, instead they are part of the 8 which you would think were the Intel ports. I didn’t find the motherboard manual helpful on this. Mea culpa, but thanks to the helpful community here it was quickly fixed!
  4. Thanks for the confirmation. I've moved the drives that were in 19, 20, and 21 over to the four bottom sockets. Now preclearing again, so far so good. I very much appreciate the help. 😁
  5. EDIT: I may have solved my own problem. I had ASSUMED (doh!) that the four ports in red in the image below were the Marvell ports on the ASRock ATX DDR3 1066 Intel LGA 2011 EP2C602-4L/D16. However, I now think this may be an error and that it's really the ports in green that are Marvell. Can anyone confirm which is correct? If it's the green that are Marvell then that's likely the cause of my problems, you need read no further, and I apologize for wasting your time. Now I need to figure out how I change SATA ports without screwing up Unraid. I posted here last week with a problem on one of my SSDs, and received some very helpful advice - thank you Johnnie Black! 😀 However, my problems are multiplying so I'm back for more help. This all began when I started seeing errors on one of my two pooled SSD cache drives. Which is what I reported last week. For now, I've removed one SSD and reverted to a single cache drive. However, the very next day after that a parity check ran overnight and one of my main pool drives had a failed write, and became disabled. I purchased a new 4TB WD Red today and ran Preclear on it so I could remove and check out the disabled drive. Preclear failed in the first stage at about 90% of the Pre-Read step. I'm having so many failures on different disks (three SATA slots in as many days) that I'm starting to wonder if I actually have a problem elsewhere. Perhaps with the SATA hardware itself? It's an ASRock ATX DDR3 1066 Intel LGA 2011 EP2C602-4L/D16 that's been running without any issues for about 18 months. I don't use any of the Marvell SATA slots, just the Intel ones. This embedded file below is the Preclear log from today, and I've attached two diagnostics files. The first from when the original HDD was disabled yesterday, and one from now just after the Preclear failed. I would really appreciate any pointers here. I've already changed SATA cables and checked connections. Many thanks.

  6. Thanks. I'll try that. However, how do I reenable NCQ so it will try again? Does a reboot do that?
  7. I recently installed a second cache drive as a pool drive. Cache now consists of 2 x SanDisk 1TB SSD drives. I've seen no symptoms of problems, but I see this in the log of the new drive after it had been running a while.. Note that the issue is 'NCQ disabled due to excessive errors'. Is this a sign that the new SSD drive is bad and should be RMA'd or is there something else I should check? I understand that NCQ is critical for SSD drive performance. Also - how do I force Unraid to reenable NCQ and try again? Thanks!
  8. Resurrecting an old thread because I'm interested as to whether this issue has gone away now we are on kernel 4.18.10? I just ran balance and it did return a lot of space to my cache drive. Could that have been lingering since before the kernel change? I've never run balance before, so perhaps it's built up over the last year or so. Just wondering if I need to add balance to my maintenance schedule with V6.6.1 and kernel 4.18.10?
  9. I've had exactly the same problem with Ubuntu 16.04 on 6.4.1 this week. I had to SSH in and edit monitors.xml in ~/.config to set the resolution back to 1024 x 768 and reboot to get VNC working again.
  10. No problem. Here they are. tower-diagnostics-20180217-1453.zip
  11. Had a call trace error overnight. This is the single call trace entry in the syslog and it relates to btrfs. Is this anything I should be concerned about? Thanks!

  12. First let me say that I'm not complaining, I appreciate all the great work you do for the Unraid community, this is just an FYI. For my system, this version is much slower than the prior. V1 used to take about 3 minutes to run a nightly incremental backup whereas V2 now takes about 30 minutes to do a full, uncompressed, backup of the same data. My data doesn't change very much from day-to-day so an incremental was ideal. Having just seen the post above on how to exclude the Plex cache folder, I'll try that and see how much it helps.
  13. Doh! I warned you it was a dumb question. Of course you are 100% correct. It even pops up a big banner warning you that Dockers will restart. I'd just slept since I set that up on the first day. So many messages, so little memory. Double Doh! Thank you.
