ReadyNAS Ultra 4 [X-RAID2] not rebuilding after inserting new disk in bay 1
Hello everybody,
After many years of joy using my NAS, 1 of my disks died (the one in bay 1). I immediately ordered new disks and hotswapped the faulty disk. But itś not rebuilding the raid!
I see a few times disk 1 is checked and then is passes the test! I see messages that disk 1 is used for rebuilding, but nothing happens. I tried restarting, with and without the new disk, but again... nor rebuild.
I added my logs for if anyone needs more info. just replace the jpg with zip.
Can I manually start the rebuild ?
Just to let you all know.
I backed up all my information and installed OS6. I even used my old "defective" drive for this, which seems fine now.
NAS is now resynching, while I'm restoring some information on it already. System seems responsive enough.
Hope everything stays fine.
Have fun!

There are also I/O errors in kernel.log

What model disk did you purchase to replace it? If you have access to a windows PC, I think the next step is to connect the drive to that PC (either with SATA or with a SATA->USB adapter), and test it with vendor tools (seatools for seagate, lifeguard for western digital).
You could also just exchange the drive. NAS-purposed (WDC Red or Seagate Ironwolf) are good choices, as are enterprise-class drives. I don't recommend desktop drives - the NAS purposed drives are similar in price and are better choices.
StephenB,
Thank you for looking into this! I bought Seagate Barracuda drives (2) and both have the same problem. I could believe 1 has a problem, but two ? It could be possible, but I would like to think not.
Could I skip this test ? And why does it say on the displa the disk has passed itś tests (again both!)
