Random Drives Dropping from Array

Go to solution Solved by JorgeB,

Hi - ongoing issue that I'm trying to diagnose.


Once every week or so a drive will randomly drop off the array.  Not the same drive - appears to be random (from what I can tell).  See first diagnostics taken just after it happened this morning.


When it does happen, I can stop VM and all dockers, but I can never stop the docker or VM services (pizza wheels for a long time).  Following that, I can not stop the array with the GUI.  See second diagnostics taken automatically because I have to give it an unclean shutdown over IPMI.


Points to note

  • All data drives (except Parity & SSDs) are connected to a SAS backplane
  • It seems to be an Ironwolf drive that drops off (although I am aware of the LSI issues with them and have set up the drives as per recommendations)
  • Every time it happens I can not stop the array


I have no idea what it could be with this, and would really love to solve it - it seems to be running a drive rebuild a lot of the time

It's happening on disk spin up, so it might be the LSI + Ironwolf issue, you can temporarily disable spin down to try and confirm.

Thanks, I've set the spin down delay to never.


I'm hoping it's not a further LSI/Ironwolf issue, since all drives have the fixes (and the drive that dropped off, and previously disk 19 are ST8000VN0022 which didn't initially suffer from that).  That said, if it's not that I'm stuck.  The PSU should cope with all drives turning on.

As a thought, I was searching yesterday and discovered that the onboard LSI 2308 was running old firmware in IR mode...

The last version I could find was  Regardless of whether it fixes my issues, would it be recommended to upgrade to the latest version and switch over to IT mode?  The motherboard preceded switching to a SAS backplane, and since it worked I didn't give it a second thought.


@JorgeB - in researching I also found your excellent post about flashing firmware, thank you

Well, after flashing the onboard LSI 2308 with the latest IT firmware (it was old and IR), Disabling EPC & Low Current Spinup on all Ironwolf drives (regardless of whether they were the models affected), and waiting, I've had no more drive issues.  Everything spins up and down normally again.


Thank you for your time and advice.
