June 20, 20224 yr OK, So I've had this happen twice... And I feel like I was doing similar things both times... Namely starting a VM that I use for Cloning Unnasigned drives... I've been trying to improve the tools I use and I think it might be something I've done... But I don't see the mistake I'm making. Recently on Jun 20 12:59:32 - My Parity drive suffered a read error and fell offline. I had this happen once before in the last week or so and ran the extended smart tests with no failures... Further the Disk that failed is my newest disk but has been running without fail for several months. I put it back in service and rebuilt the parity with no trouble but it just did it again today while I was trying to edit a couple of the VM's that I'm using (Clonzilla and GPartEd). Thanks for any input. I'm ordering a new 18tb EXOS to install as parity, and I will RMA the 14TB jupiter-diagnostics-20220620-1322.zip
June 20, 20224 yr Looks like a power/connection problem, suggest replacing/swapping cables/slot to rule that out.
June 20, 20224 yr Author It's just weird that it's all of a sudden an issue... But there's always a chance ive degraded some connection with the other things I've been doing... I was just concerned that I was casuing it by connecting another /Dev/SD$ in a vm config.

Don't see how that be be related, sometimes users pass-trough a controller by mistake to a VM, so when the VM starts all disks connected there are lost to Unraid, but that's not the case here.
June 20, 20224 yr Author Thanks for taking a look... I didn't think I was doing it wrong, but it seemed to coincide. I suppose it's possible I'm getting vibration... There is an extension on that connection that I should possibly get rid of. Or at the very least check it for solid connection. oh, and I have definitely passed through the wrong controller back when I was first setting things up.
June 21, 20224 yr Author Further input for interests sake: I mounted a drive using Unassigned Devices and instantly lost the parity drive to a read error... The unassigned drive is inserted in a slot load tray above my parity drive, and not in the best of health. (Hence the reason I'm trying to access it.) This slot load bay is also in use when I was launching the VM's that I thought were causing me the problem before... I'm waiting on the replacement drive this week. Oh the drive the system is repeatedly warning about is the drive I mounted to do data recovery on. jupiter-diagnostics-20220621-0933.zip

June 21, 20224 yr Author Yes, it's on a hot swap capable Sata connection I've been using this bay as hot swap for over 4 years... Though the Sata controller has changed a few times over the years. The current connection is on the NZXT Mainboard and the port is set to Hot Plug in BIOS.

The only differentce with the Parity drive is that it is mounted to a seperate plate from the other Array disks, and there is a short Sata extension cable connected... AND IT"S ON THE SAME POWER LEAD AS THE REMOVABLE BAY!!! (OK thought of that as I typed...)
June 21, 20224 yr Author The Power Supply is a beQuiet 1000W that is nowhere near the limits... Is there a way to see if the drive looses power?
June 22, 20224 yr Author The Power Supply is a beQuiet 1000W that is nowhere near the limits... Is there a way to see if the drive looses power? I wonder if using a separate line for the Parity drive might help... I don't think it should, if I'm reading the manual correctly, but maybe just moving it a little farther away... Worth a shot.

June 22, 20224 yr Author That was my read as well... So even if I use a seperate cable it will not isolate the one drive from the external bays.

July 4, 20224 yr Author Considered wiring a Cap into the 12V rail at the plug for the Hotswap bay, but tried plugging a separate cable in for it rather than running it off the cable that I had in place... Seems to be holding now. Yay, time to start building the parity again.
