I just swapped this drive into my other server and set preclear to just verify signature and it gave the same errors. Looks like I'm unable to run SMART reports on the drive until it's been added to the array. Is that correct? Guessing maybe both of these drives came from a bad batch of drives but at least I can still return them.

ok, moved the drive to a different bay again. Was able to finish step 3 but then failed step 4 with the following log: In Summary: Drive One had reallocated sectors during preclear, pulled that drive to return. Drive Two (This One) has failed step four twice now. First time was due to connection problems that filled the log. I swapped bays to use a different cable and started again.

Dammit, I loaded the wrong diagnostics file. Sorry about that. photoserver-diagnostics-20260316-0541.zip

Having a hell of a time preclearing two new 28tb drives. First drive started reallocating sectors so I pulled that to return. Drive 2 failed step 4 the first time I ran it. After swapping it to a different bay, it successfully finished step 1, but essentially never started step 2. Once step 2 began, it was at 0 mb/s or 1 mb/s but never any faster. After ~12 hours it was still at 0% complete. Diagnostics attached. photoserver-diagnostics-20260314-0610.zip

9QSQ is the drive the preclear is running on. I just put it in another bay and started preclear again. Will replace cables once this finishes.

First time I've encountered an error during preclear. Steps 1-3 completed successfully but step 4 failed. Error says "cat: write error: No space left on device" Diagnostics attached I was able to reboot the server and start a new preclear, but that will obviously take days to complete and was hoping for some guidance before it potentially finishes. photoserver-diagnostics-20260314-0610.zip

I think this is pretty straightforward but wanted to check first. Was running preclear on a brand new 28TB drive and at 97% complete it started throwing out reallocated sector warnings. It got up to 20 sectors over the course of two hours and I ended the preclear. Is there any recommendation where the best practice isn’t to simply return the drive and get a new one?

Under Routing Table? I’m only showing docker0 and eth0 there. Docker0 was not there last night when I removed the NIC but was there this morning when I restarted. Edit: looks like the routing table reverted back from the changes I made last night. I’m unable to delete, modify, or add any new routes though. How do I make changes here? Well, whatever changes I made caused me to lose LAN access.

I had an Intel NIC to avoid the onboard Realtek but wanted to add a new GPU to handle transcoding and the GPU needed the slot. After removing the NIC, I switched the network settings over and had internet and LAN access last night. After waking up this morning, I restarted the machine and now internet access is gone. I can still log in to the machine on the LAN, but I do not have any internet. These are settings I know very little about, so I'm positive this is just something I need instruction to setup properly. tower-diagnostics-20251218-0634.zip

Unsure what's causing this or how to resolve. My server was working normally when I went through the upgrade process to 7.0. As soon as it restarted, Disk 7 was now listed as Disabled. Logs attached. tower-diagnostics-20251214-1358.zip tower-smart-20251214-1400.zip

Once I add the new parity and move the current parity over, it will give me an additional 10tb. I normally upgrade my drives before this point, but it kind of creeped up on me. Will upgrade software once I get the drives settled. Just noticed my dockers are empty. Is that normal from rebuilding a drive, or did something get deleted in the process? Edit: Was able to add Plex back using "Previous Apps" but my database was gone. Have to rebuild the media library from scratch.

I redid all the SATA cables and did the power cables this time. I'm at a million writes on the disc rebuild without any errors. Assuming this completes without issues, is there anything else I need to do due to the disk errors?

Not without taking apart another computer. Is there any way to test other than trial and error? So everything in diagnostics looks good? Is there a risk of data loss/corruption from the multiple disk errors? Fortunately I wasn't writing anything at the time. I'm going to attempt to unplug and reseat all the SATA and power cables again; do I just need to try to continue with the data rebuild as normal or anything special to do at this point?
