Bit of a strange one here, this server has been running fine for a couple of years now, but 3 times this week, I've gotten a disk disabled error on 3 different disks, for the first 2, I removed the drive from the array, started array in mainteance mode, stopped array, re-added disk and rebuilt over the top, which worked fine, the first 2 drives this happened to are once again working fine, they are disks 6 and 8 but about an hour after the rebuild of disk 8, disk 7 is now disabled.

 

I suspect it might be the HBA on the way out and have ordered another one, but was hoping my diags might give someone with a bit more experience with unraid might offer more info here.

 

Thanks in advance for any clues!

added SMART tests

If you want to check if the drives themselves are healthy then the extended SMART test is the best way to do this.

 

You can also get the sort of symptoms you describe of what appear to be random drives disabling if you have power related issues (either in the cabling or the PSU itself).

Ran an extended test on the first drive that went into error, looks fine to me, as the initial error seemed to point to failure to spin up after spinning down, I've turned spin down off, will run it like this for a week and see, then try spin down again and monitor

I think the drives are probably OK, especially since it is different drives causing problems.

 

Looks like all the affected disks are on this controller:

0a:00.0 Serial Attached SCSI controller [0107]: Broadcom / LSI SAS2008 PCI-Express Fusion-MPT SAS-2 [Falcon] [1000:0072] (rev 03)
	Subsystem: Dell 6Gbps SAS HBA Adapter [1028:1f1c]
	Kernel driver in use: mpt3sas

 

Yep all drives are on that HBA, I've ordered a new one, and a 40mm fan for it, as well as new cables, hopefully I won't need them, but I do like to have spares
