I'm running unRAID v5.0-rc8a and have come home to find my syslog filled with errors.  They occurred whilst the mover script was running - as a result my syslog was huge, and since the same errors were repeated over and over again I've just attached an excerpt and quoted the repeated lines below:

 

kernel: handle_stripe read error: 1943077040/2, count: 1

kernel: md: disk2 read error

 

and

 

kernel: sd 0:0:2:0: [sde]  Result: hostbyte=0x00 driverbyte=0x08

kernel: sd 0:0:2:0: [sde]  Sense Key : 0xb [current]

kernel: sd 0:0:2:0: [sde]  ASC=0x47 ASCQ=0x3

kernel: sd 0:0:2:0: [sde] CDB: cdb[0]=0x28: 28 00 1a 84 3d 50 00 04 00 00

kernel: end_request: I/O error, dev sde, sector 444874064

 

I suspect from searching the forums that I either have a loose/dodgy cable or a bad disk.  I understand I will need to carry out a SMART test to confirm which. Here are the results:

Am thinking most likely a dodgy cable or sas card - is there anything else I should be considering/trying?

 

Cheers

I've re-seated the cable connectors and am going to try running the mover script again tonight.

 

Am keeping my fingers crossed..!

Just to update, mover ran successfully overnight with no errors. Looks like it was just a loose cable
