xdriver Posted March 1, 2023 Share Posted March 1, 2023 (edited) I am replacing a failed drive with a larger drive than my current parity. Old parity is 12TB, new Parity is 14TB and the failed drive was 6TB. That being said, the new parity will end up being the 14TB and the replacement for the 6TB will be the old 12TB parity. My question is, is there any way to Pause the parity rebuild and shut down the server to cool? I believe I am having an overheating issue that is causing my server to crash, and I would like to do the rebuild in increments if possible. What is the best way to monitor the CPU temperatures in Unraid, and will the server log record the crash if it is heat related? If the server crashes during the parity rebuild, will I lose data?

itimpi Posted March 1, 2023 Share Posted March 1, 2023 There is an option to pause the parity build on the Main screen. However if you shutdown the server Unraid will start the parity build again from the beginning on next boot. if you install the Parity Check Tuning plugin then it has an option to restart the array operation from the point previously reached on the next boot. However that functionality does rely on you achieving a tidy shutdown - are you managing that? There are also temperature related options, but they are geared around the drive temperatures and not the CPU temperature so may not be of any use to you. Quote Link to comment
xdriver Posted March 1, 2023 Author Share Posted March 1, 2023 I don't happen to see a pause parity on the main screen, just a "cancel." I can run it for probably 10 hours and be safe to do a clean shutdown, but as it stands now, the server will just crash/shut itself off. Are there any plugins that monitor CPU temp and report in a crash log? Do drive temps get reported in a crash log? I have it set to save the log to the flash drive, but it crashed today at maybe around 10am and I do not see a .zip log right now. Any idea why that would be? I probably do need new hardware, but if it is something basic, I'd rather just repair it. Quote Link to comment
JonathanM Posted March 1, 2023 Share Posted March 1, 2023 I don't believe there is a way to pause the parity copy portion of the parity swap procedure. Any way you can temporarily cool the server's environment to help it limp along for the duration? Quote Link to comment
xdriver Posted March 2, 2023 Author Share Posted March 2, 2023 The heat is just an assumption, there was some question about USB ports being above voltage, but I have tested them all to be under 5 volts, more like 4.8. I was hoping there was a way to check the CPU temp while the server was running to either confirm or rule it out. Quote Link to comment
JonathanM Posted March 2, 2023 Share Posted March 2, 2023 Some motherboards work with the cpu temp plugin, but it's not universal. Quote Link to comment
xdriver Posted March 13, 2023 Author Share Posted March 13, 2023 Is there any possibility that my Dell UCSA 801 Poweredge sata raid controller E105106 could cause a crash and to shut down, and if so, how would I test it? Quote Link to comment
