August 2, 20232 yr Community Expert Looking at my nightly email from unraid about the array's health report, it shows as 'Passed' but I notice that all the drives were spun up (except for 1 anyway). So I log into the server to see if they still are, and they were all still spun up, so I click the button to spin them all down to see if they'll stay down but all the icons do is spin. I try each drive individually, with no effect on any of them, so I open up the log to see if there's any spindown commands noted. Turns out two of the drives were disabled, and the emhttpd process had segfaulted shortly after the drives show disconnected and re-connected. The dashboard continued to show no issues and send an ALL OK Bro! email..... If I hadn't noticed the drives spun up and investigated, it might have been a while before I would have any reason to look at it... What's the point of the health email if it doesn't report the actual health of the array?
August 2, 20232 yr Community Expert The disk is not disabled but it should report the read errors, please post the diagnostics.

August 2, 20232 yr Community Expert Yeah, there were write errors for both, so they should have been disabled, likely weren't because of the emhttp segfault just before that, first time I see that, you can create a bug report but it might have been a one time thing.

The gui no longer reports any progress on the parity re-build, I just have to wait for it to finish and re-boot to get the dashboard back. This one at least sent the correct [FAIL] email, which leads me to question whether it's a 6.12 issue? Edited April 5, 20242 yr by Michael_P deleted diags exposing passwords

Since moving to 6.11 it's happened each of the times one has dropped offline, this is the 3rd time. The other two times were during parity re-builds after upgrading a drive and one of the others dropped (I rarely get a clean parity check/re-build on the first try without losing a drive likely due to power which I'm working on again..)
