Hi Everyone,
I am having a bit of a strange issue with my FreeNas deployment. I have a 45 Drives Solution with 10 x 10TB SATA Drives. These are all in a RAIDz2 pool.
The issue is that drive will randomly fail, we have tried replacing the drives and controllers and are still having the same issue. The drives will show a high number of write failures and 6 read failures and no checksum failures. I have found You can offline the disk and replace it with itself and then another disk will fail. So to me the disks seem fine.
I have had a bit of a poke around and can see the following error:
SCSI sense: UNIT ATTENTION asc:29,0 (Power on, reset, or bus device reset occurred)
(da9:mpr1:0:9:0): Error 6, Retries exhausted
But I have no idea what is causing it, or if this is even indicative of the route cause.
Another peculiarity is that rebooting the unit will clear all the errors and the pool goes back to healthy again.
Any help or pointers would be much appreciated.
Kind Regards,
Ryan
