  1. Got it. Thanks again for the help!
  2. Oddly, after crossing about 5.5% parity check completion, the parity speed has returned to normal levels (currently ~142MB/sec). I am also seeing more normal CPU utilization (~20%, no cores maxed). I'm not sure why, but I'll take it. I'll keep monitoring this for a few more hours, and will mark this solved if the slow parity issue doesn't return. In the meantime, if there are any other issues I should look into, I welcome the pointers. Thanks to Squid and JorgeB for the help!! M

  4. Update: Docker rebuild seems not to have solved it. I did notice that my Arq backup to unraid was doing a cleanup task, so I paused that. Since doing that speeds have gone from 1MB to ~20MB, still well below the normal ~100MB average.
  5. Hey Jorge, I dont seem to have the system report binary installed, nor do I see it in nerd pack. Any ideas?
  6. I've just deleted my docker.img, reinstalled dockers, performed a clean restart, but the parity issue seems to remain...
  7. They seem to be... All are reachable by web. Any idea how I can I figure out which docker is doing that? (And predictable follow up question): Any suggestions for how to solve it? EDIT: As I sent this, Sonarr went unavailable and seems to be unable to be stopped by the webgui. I think maybe thats the one... Thanks, Squid!
  8. Greetings fellow UnRAIDers, and happy new year! I'm seeing some very slow parity check speeds (see below) on my monthly parity check today. I did reboot a couple times today after some slowness on the webUI and a docker crash (everything unavailable). The reboot seems to have sorted the docker problem, but now I have a new issue: slow parity speed. It's max/min is between ~25MB/sec and under 1MB/sec, which is far slower than normal. Enclosed are diagnostics taken during the slow parity check, and a couple screenshots. Any help is very much appreciated. Cheers! EDIT: Also should mention that I am seeing sustained high CPU usage on the dashboard page (yet not when using htop). Several cores at 100%, overall between 30 and 80% cpu load. Not sure if this is related or not...
  9. +1, I would love to have a Caddy Docker for UnRaid! Thanks for considering doing that!
  10. Quick (and probably obvious) question: How does one update the jitsi components when deployed in this way?
  11. mattyx

    Jitsi?

    FWIW, I would love this. +1 demand unit.
  12. Just curious what this assertion is based on. Could you share some details?
  13. Hmm. I'm observing either that this feature is broken, or something is confusing it. I confirmed manually that there are no overlapping files, the parent folders are identically named, and I even copied a single season, rather than the whole lot. No dice, I'm only offered to replace or stop. EDIT: I totally missed the part where I have to hold option. My mistake! Sorry! It's working now. Thanks so much for the replies!
  14. Unless there's a merge feature in the Finder (there very well may be), the problem is that shows and even portions of seasons are split between the correct and incorrect locations. I tried what you suggested, but I am only offered "replace" or "stop" when I drop the folder. Any ideas?
  15. Thanks for the tip! One challenge is that there are many subdirectories, so moving them manually will be time consuming (and tedious). I am wondering if there's a sweet one-liner someone could suggest that would move everything up a directory level while preserving the subdirectory structure. Example: Moving files from /mnt/user/TV/TV/Show/Season-06 to /mnt/user/TV/Show/Season-06 (which may already exist and have some content). Thanks!!
  16. Hi there, I have noticed recently that my TV directory has a nested TV directory within it that contains a subset of shows and seasons of shows. Obviously, this is not ideal, although Plex seems fine with it. 2 questions: 1. Aside from reviewing my docker paths, what else can I do to determine the cause of this? 2. What is the best way to move these all up one directory (from /mnt/user/TV/TV to /mnt/user/TV) while preserving directory structure and such? I can do this with mc, but I'd prefer a one-liner than spending the time to do it manually. Thanks!
  17. Found the issue: DNS rebinding protection that is provided by Google's DNS servers (default on google wifi). More info here: https://support.google.com/wifi/answer/9144137 I changed to cloudflare's DNS, and I can now use the unraid.net address. Hopefully this helps someone.
  18. Sometime last week, following a reboot, I stopped being able to reach my local UnRAID device from its hashed unraid.net address. I am still able to reach it by entering the IP. The error thrown in Chrome is: "server IP address could not be found". I thought I read something about Google Wifi potentially being the culprit (I use that), but now I cant find it. I have a local dns entry that is also not working as a result of this. Anyone have any ideas? I've cleared cookies and rebooted everything... Thanks!
  19. One final question: is there any reason to not delete the key from memory once the drives are unlocked? I've recently begun formatting and encrypting and I'm trying to understand if there's a scenario where I would want that key to remain in memory. Thanks!
  20. OH! I think I (finally) had the lightbulb moment. I was thinking the key would remain on Unraid (somewhere on the USB stick); I didn't consider that it would be uploaded from another secured machine each time. This now makes a lot more sense, as does your initial comment about deleting it. Thank you very much for the clear explanation, I hope it helps more people than just me.
  21. Got it, that makes sense. Thanks! Summarizing (for myself): Using a keyfile would be good for a threat model involving array disks being stolen (and for ease of use), but probably not the best if you're concerned with the entire server being stolen. EDIT: This assumes the key stays on the Unraid USB stick, which it does not. It is uploaded each time, in place of manually entering a password. limetech clears this up on page 2, but I thought it was worth an edit here to call out my mistake.
  22. So if I am understanding the flow here (I don't think the lightbulb is on just yet): Create passphrase key doc, add it to LUKS Reboot, using passphrase doc. Start Array <Optional, good for security> Delete old keyfile <Mandatory if you did #4> Regenerate and re-add keyfile to LUKS before next reboot/power failure, or...? I assume you'd fall back to a password that you'd manually enter...?
  23. Doesn't that undo the protection of FDE in the first place, since the key is sitting unencrypted on the box? It seems to me that if your threat model includes physical theft of the server, this might not be a good idea. Honest question; apologies if I am missing something obvious.
  24. The repair appears to have worked, and the array is now able to start. I don't see any data loss and only 2 files in the lost+found folder. Many thanks!
  25. Got it. Thanks! I'll report back as to how it goes.
