I got a couple of errors this morning - first my cache drive (SSD) has "current pending ecc cnt is 1" and then almost immediately that it was returned to normal. about 5 hours later, I got an error that there's a disk with read errors. My syslogs are attached - please let me know if there's anything else I should post.

 

Description: Array has 1 disk with read errors

Importance: warning

 

Disk 17 - TOSHIBA_HDWG480_X170A07SFR0H (sdu) (errors 2)

 

Of course I'm leaving for vacation this week. Should I shutdown the array until I return?

Please post the diagnostics.

There's no SMART report for that disk, it may have dropped, reboot and post new diags after array start.

Thanks JorgeB!

SMART looks fine, could be a power/connection issue or spin down related, I would replace/swap cables first and then see if it happens again.

Thanks - I reseated the power and cables, no dice. moved the drive to another slot in the bay, no dice. 

I think I saw somewhere that I have to unassign, start the array and then re-assign for it to recognize the drive again? 

Changing cables/slot won't re-enable a disabled device, for that you need to rebuild, but only rebuild on top if the emulated disk is still mounting and contents look correct.

Would it be safer for me to shuffle the contents out of the drive to the rest of the array? Or am I just creating more work for the array?

 

Thank you!

As long as the emulated disk is mounting, that will only create more unnecessary activity.

This will sound dumb - but how do I confirm if the disk is actually mounting? When I click the red X, Unraid happily tells me it'll spin-up the drive - and I see temps. I see the light for it light up during the spin-up operation. 

 

I checked on /dev/disk/by-id/ and see it listed there. 

 

Thank you. 

Post new diags with the array started, or look at the filesystem stats on main for that disk, if there's used/free space it mounted, if not it will show unmountable there.

Thanks - procedure worked as expected - drive is currently rebuilding. 

 

I appreciate you!

hmm looks like that physical slot on my case is bad (I moved it back to the original location). As the rebuild progressed, I got a bunch of crc errors. Once the rebuild is done, I guess mark that slot as bad and move drive physically to another?

If it's an expander backplane slot try a different one, if it uses a SATA cable try replacing it.
