Disabled Drives on TWO Unraid Systems

Wow,

I've got crazy issues with Unraid all of a sudden.  I have two machines and they both have failed drives according to the Main screen.  :'(

I hope someone knows what to do to assist.  I'll update here if I find more information as I try to interpret my logs (but I don't really know how).

Thanks,

Russell

On Palmwood it looks like my HGST drive ending in RHS has the following error:

On Zurlo it looks like my Seagate drive ending in YB5 has the following error:

Sure seems strange to have the same problem on different make of drives on two different systems at the same time... Yikes!

I hope a guru can help me.

It's even worse than I thought...  On Palmwood, I have one errored drive and one missing (see attachments).

I can't see anything bad in the SMART reports on all nine drives, so I'm really confused.

Swapping out cables, I've got no changes on Zurlo...

But on Palmwood, I was able to get a little difference:  Now Disk 3 (ZUT) is green, but Used/Free space shows "Unmountable" and Disk 5 (RHS) as "Not Installed."  Palmwood is making some shares available.

Hoping for some advice.  Do I dare try to do some emergency backup?  (These systems were supposed to be backup to each other - I have offsite backup too, but it isn't complete.)

Shutting down both systems as I wait for advice.

Disks dropped offline on both servers, upload new diagnostics for zurlo also after the reboot so we can see all the SMART reports.

For Palmwood:

Disk5 needs a new SATA cable, almost certainly the reason it dropped offline and got disable:

199 UDMA_CRC_Error_Count    0x000a   053   053   000    Old_age   Always       -       7914732

Disk4 also has abnormal number of CRC errors:

199 UDMA_CRC_Error_Count    0x000a   200   200   000    Old_age   Always       -       116

Other disks also show some errors from 4 or 5 to 50, these are not normal and cable need to be replaced if the attribute increases by 2 or more.

Disk3 is missing, powerdown, check/replace both cables and power back on.

After checking/replacing at least the cables for disk 3 and replacing the SATA cable for disk5 power back on and post new diags.

Thanks Johnnie,

Off to get a bunch of new cables.
