Okay, I'm bringing this topic back with an update. I did lots of testing and never figured out what was going on here, plugging things into different ports and replacing switches, etc. The Orbi issue of the hardwired ports dying with no warning got so bad (daily) that I wrote it off as the hardware failing and generating some kind of incompatibility with something on my network. I sold them to someone for cheap and bought a Ubiquiti Dream Machine and 3 access points lites to replace everything. I have the 3 APs hardwired into the UDM and the 4th port has an Netgear unmanaged 8-port switch. The unraid server is plugged into that Netgear switch. along with a few other small things (a raspberry pi, etc). I segmented a bunch of stuff into VLANs for IoT and generally things are way more reliable. HOWEVER, I am still occasionally having this issue where it seems like the Unraid server is killing the network and I have no idea why. Example, I noticed the network seemed slower yesterday at some point, but it still worked and I was busy with the kids, etc. By 10 PM last night I get "the wifi isn't working at all" from my wife and alexa is complaining "no network" etc. I reboot the UDM, no change. wifi is up and my phone is connected, but traffic just isn't working at all. I go downstairs, power off the unraid server manually. The wifi instantly starts flowing traffic at full speed and suddenly my light switches and alexa respond, etc. Any tips on what to do here? I can run a trace and know enough networking to be dangerous but I'm not a pro. I have a UDM that I can go through logs, etc. I'm trying to figure out how to troubleshoot what is happening in these situations where it seems like something in the unraid server is DOSing the rest of the network at random intervals (monthly?) I'm wondering if I need to do some packet captures or something when this is happening, but I'm not sure what I'd look for or what tools to use. Suggestions welcome!

Howdy all, this is more of a general networking issue, but it's specific to my Unraid server and I would love any thoughts you have on how I could do further troubleshooting. I have been chasing network failures off and on for a couple of months now after moving to a larger house. Before that I had no issues at all. The issue is that occasionally all hardwired ports on the RBK50 Orbi router fail and will no longer respond at all, but wireless internet continues to work fine. When that happens, you can't connect to the RBK50 or the internet from anything hardwired. Satellite RBS20s still work fine if they are connected wireless and the router still responds if you're using the Orbi phone app from your phone. While troubleshooting, I think I tracked the problem to my Unraid server. It appears that SOMETIMES when my 'Anniversary' build Unraid server (which runs a GA-7PESH2 motherboard) is plugged into the RBK50 at all (even into a Netgear switch that is plugged into the RBK50) it kills all the hardwired ports on the RBK50. It doesn't happen all the time and once it has happened, the only way to fix it seems to be unplugging the Unraid server from the network and fully power cycling the RBK50. If you plug the Unraid server in again immediately, it often kills the RBK50 wired ports again. If you wait a while and plug it back in, it seems to often go back to working for days or weeks. I can't find any logs on Unraid or the RBK50 that point to any issues. I am out of ideas besides "replace the RBK50". Any thoughts on what I could be missing here?

Just finished. No issues. Gonna rerun the rest!

I'm rerunning the same drive from scratch and so far it looks like the issue is resolved. It made it through the clear and the zero and is almost done with the post-read. Thanks!

Awesome! I can rerun it when you push an update.

Update on current status. I saw two similar issues previously and wasn't sure if they were the same. Some of the drives seemed to restart over and over, which is the log posted above. Others seemed to get "stuck" at 99% and I didn't pull the logs to find out if they were showing the same thing. Fast forward to now, the 3.0 TB drive I started a new preclear on (erase and preclear, 1 cycle, no pre-read) has been running for about 24 hours. It went through 25%, 50%, and 75% and sent email/UI status correctly. It looks like it hit 99% status and stopped earlier this AM. The UI under unassigned drives still says 99%, but one more email/UI update fired around 5 AM saying "Erasing started on ..." with no percentage, so it almost feels like it started over. I'm not seeing the same results in the logs yet, they just seem to have stopped: ErrorWarningSystemArrayLogin DOWNLOAD Feb 13 07:17:27 preclear_disk_PK1234P8JHP5PX_17218: Command: /usr/local/emhttp/plugins/preclear.disk/script/preclear_disk.sh --erase-clear --notify 3 --frequency 4 --cycles 1 --skip-preread --no-prompt /dev/sdk Feb 13 07:17:27 preclear_disk_PK1234P8JHP5PX_17218: Preclear Disk Version: 1.0.9 Feb 13 07:17:29 preclear_disk_PK1234P8JHP5PX_17218: S.M.A.R.T. info type: default Feb 13 07:17:29 preclear_disk_PK1234P8JHP5PX_17218: S.M.A.R.T. attrs type: default Feb 13 07:17:29 preclear_disk_PK1234P8JHP5PX_17218: Disk size: 3000592982016 Feb 13 07:17:29 preclear_disk_PK1234P8JHP5PX_17218: Disk blocks: 732566646 Feb 13 07:17:29 preclear_disk_PK1234P8JHP5PX_17218: Blocks (512 byte): 5860533168 Feb 13 07:17:29 preclear_disk_PK1234P8JHP5PX_17218: Block size: 4096 Feb 13 07:17:29 preclear_disk_PK1234P8JHP5PX_17218: Start sector: 0 Feb 13 07:17:35 preclear_disk_PK1234P8JHP5PX_17218: Erasing: openssl enc -aes-256-ctr -pass pass:'******' -nosalt < /dev/zero > /tmp/.preclear/sdk/fifo Feb 13 07:17:35 preclear_disk_PK1234P8JHP5PX_17218: Erasing: emptying the MBR.

Most of my drives are all the same, HGST Deskstar 3.0 TB drives. It had no problem with the smaller laptop drives, but had this behavior on all of the larger ones, so it seems like it might be related to the size of the drive. I'm rerunning one of them with the updated plugin and I'll see what happens.

I think that is where I'm at. I'm only running one drive this time and I'm getting the same behavior (from the log above). It's at about 70 hours and has restarted at least 2-3 times from what I can tell. I haven't tried stopping and restarting it yet. I will probably wait and see if I can find another solution first. I saw something about a docker container for preclear and I might try that instead if I can't figure out what is going on.

I'm having the same issue where drives keep "erasing" over and over again or getting stuck at 99%. I had two drives that were "erasing" for 200+ hours before I killed the process. I started them over and they both both hung at 99%. I started one of the drives by itself and it keeps getting to the end of the erase and restarting. I'll post the logs here and a few notes: These are drives connected with a usb dock and I was able to clear 8-10 other drives before this. All of the ones failing are seagate or hitachi 3-4TB drives. I have the unassigned drives plugin, but they aren't mounted. I'm running them as "erase and clear" with the gfjardim script, 1 cycle, no pre-read and this is a sample of what I'm seeing: Feb 03 08:48:17 preclear_disk_ZFN1PJC3_650: Command: /usr/local/emhttp/plugins/preclear.disk/script/preclear_disk.sh --erase-clear --notify 3 --frequency 1 --cycles 1 --skip-preread --skip-postread --no-prompt /dev/sdk Feb 03 08:48:17 preclear_disk_ZFN1PJC3_650: Preclear Disk Version: 1.0.9 Feb 03 08:48:17 preclear_disk_ZFN1PJC3_650: S.M.A.R.T. info type: default Feb 03 08:48:17 preclear_disk_ZFN1PJC3_650: S.M.A.R.T. attrs type: default Feb 03 08:48:17 preclear_disk_ZFN1PJC3_650: Disk size: 4000787030016 Feb 03 08:48:17 preclear_disk_ZFN1PJC3_650: Disk blocks: 976754646 Feb 03 08:48:17 preclear_disk_ZFN1PJC3_650: Blocks (512 byte): 7814037168 Feb 03 08:48:17 preclear_disk_ZFN1PJC3_650: Block size: 4096 Feb 03 08:48:17 preclear_disk_ZFN1PJC3_650: Start sector: 0 Feb 03 08:48:20 preclear_disk_ZFN1PJC3_650: Erasing: openssl enc -aes-256-ctr -pass pass:'******' -nosalt < /dev/zero > /tmp/.preclear/sdk/fifo Feb 03 08:48:20 preclear_disk_ZFN1PJC3_650: Erasing: emptying the MBR.
