tredman Posted June 9, 2020 Share Posted June 9, 2020 I'm new to unraid, so please go easy.. My system was set to do a parity check last night. I woke up this morning to see a ton of read errors and one drive disabled. I've since pulled the disabled drive and am in the process of rebuilding. I've previously had read errors on the array, but a reboot has usually cleared them (the drives are oldish and I am about to start slowly swapping them out). I downloaded the diagnostics - they are attached. Could someone with more knowledge than me advise if there is something more serious than one drive failing? Thanks for any help. tower-diagnostics-20200609-1125.zip Quote Link to comment
JorgeB Posted June 9, 2020 Share Posted June 9, 2020 Same error on multiple disks: Jun 9 05:48:00 Tower kernel: sd 1:1:0:3: [sde] Unaligned partial completion (resid=56, sector_sz=512) Googling this it looks like it's a bug/firmware issue, there was a fixed for the standard Linux LSI driver, no idea about your HP RAID controller, note also that RAID controllers are not recommended for Unraid.

Yeah, that happens all the time - from what I see its not a problem and can be stopped with a bios upgrade. I have a microserver gen 8, I'm not using its RAID functionality and the drives are passed straight through Quote Link to comment

That is true, but I have a microserver gen 8 so I think I don't have that option. I don't think this will cause the issue I had though - with a drive marked as failed and read errors?
