Volume expansion failed-many times
I have a Ultra 6 that had 3 X 3TB WD Red drives in it. I added 3 more. The drive expanded to include the 4th drive, but didnt seem to recognise the other 2. Then it did, but said that the 5th drive was dead, then it wasn't dead, and it found the 6th drive. It started expanding into the 5th drive, but has come back "Volume expansion failed", followed by "incomplete file system expansion detected. Resuming . . . " This has now gone on for 36 hours. If I look in the volumes, it says I have 6 drives installed & all fine. If I look at the system though, I only have 5 drives. A Western Digital scan of the 5th drive says it is fine, and I while I might not be able to expand to the full extra 9TB, I was not expecting to hit the limit at just over 3TB. Anyone have any ideas on this?

- What disks were installed when you last did a factory default? If the answer is 2x3TB disks or less it sounds like you've hit the 8TB expansion limit. You can only expand your volume by 8TB over the life of your volume. Adding 3x3TB disks would be pushing that limit of 8TB.
As for a disk being reported as failed there may be some clues in the logs. Download your logs (Status > Logs > Download all logs), extract the zip contents and look at the disk SMART logs. - I have not done a factory reset at all. The first build (at factory default) was 3X3TB, and the only addition was the 3X3TB extra. At the time of the addition I did not realise that I would max out at 8TB addition, but I do now. The problem that I am having is after only 1X3TB. On the smart logs, each disk says "SMART overall-health self-assessment test result: PASSED" & "SMART Error Log Version: 1 No Errors Logged". I should say that the Western digital scan showed 4 partitions - 2 very tiny ones, but 2 good sized ones. I assumed that these two main partitions were where the ReadyNas was doing the expansion. If that is so, then it was about 25-30% through the disk.
