There's a lot of info here. You are correct my config is sda and sdd. I may be missing something but this looks like it passes self-test. Your help appreciated!
Here's the logs from one as it is too long.~ # smartctl -a /dev/sdd

Well, that is clear:=== START OF READ SMART DATA SECTION ===SMART overall-health self-assessment test result: FAILED!Drive failure expected in less than 24 hours. SAVE ALL DATA.<snip>5 Reallocated_Sector_Ct 0x0033 001 001 005 Pre-fail Always FAILING_NOW 1058So the problem is the Reallocated_Sector_Ct. I have no idea why that looks different in the GUI. The disk itself has recorded 4 errors at 5921 power-on hours (which is almost 300 hours ago), at sectors 57195660, 57195648, 57195713 and 57195707. So that 24 hours is a bit exaggerated. Assuming that are 4k sectors, that is around 218GB from the start of the disk, so that is well inside the data partition.

So I looked through it more carefully, right in the beginning of the "SMART Data Section" there is a line "SMART overall-health self-assessment test result:" Drive A shows "Passed", Drive D shows "Failed". As D is the RAID 5 parity drive, this explains why it's degraded, but I can still access the data and the rebuild fails while processing. Have I got it?0

There's a lot of info here. You are correct my config is sda and sdd. I may be missing something but this looks like it passes self-test. Your help appreciated!
Here's the logs from one as it is too long.~ # smartctl -a /dev/sdd

jahmon said:So I looked through it more carefully, right in the beginning of the "SMART Data Section" there is a line "SMART overall-health self-assessment test result:" Drive A shows "Passed", Drive D shows "Failed". As D is the RAID 5 parity drive, this explains why it's degraded, but I can still access the data and the rebuild fails while processing. Have I got it?More or less. There is no parity drive in RAID5, the parity blocks are equally distributed over all disks. This is done to maximize the read speed (on a healthy raid array the parity blocks are not used for reading, and so it's a waste to not use a whole disk + it's bandwidth) and to minimize the penalty when a random disk fails.The raid manager is pretty dumb. When rebuilding the array is simply calculates the content of the 'new' disk from the total surface of the 3 others (the raid manager doesn't know about filesystems, and so doesn't know if a particular sector is used or not), and writes that to the disk. When a write error occurs the new disk is dropped, and the rebuild fails. And worse, if a read error occurs the relevant disk is dropped, bringing the array down.
