Hard drive failure during rebuilt - next steps?

Hi there,

 

I have just undertaken an upgrade of the hard drives in my ReadyNAS314 as follows:

* Bays 1 & 2 - 2 x 6TB WD Red Pro - to remain the same

* Bays 3 & 4 - 2 x 2TB WD Red Pro to 2 x 6TB WD Red Pro

 

I swapped out Bay 3-4 at which point the RAID started to rebuild. I've returned overnight to see a warning that the NAS is degraded and the drive in Bay 1 has disappeared from the 

 

What I really need help with is:

1. How can I check whether all my data is ok? 

2. How can I check whether this is a drive failure or issue with the NAS. The console displays the volume as missing (rather than corrupted) - image below

3. What to do next!

Many thanks

Looks like a bad disk to me. I can see I/O errors.

Is your backup up to date?

Hi mdgm,

 

Back-ups are up to date though I'd rather not restore from them as it's a bit messay. 

 

Am not sure in which log you're seeing the I/O errors. 

 

When I looked at the logs on the ReadyNAS portal it looks like the NAS had finished resyncing with the new drive in bay 3 before the drive in bay 1 failed. Am I safe to stick a new 6tb drive into bay 1 to restore my RAID5 failover or are there bigger issues that have been in play for longer?

 

Apologies in advance if these questions seem dumb 😞 and thanks again for all your help.

Looks like you got lucky, the RAID is viable but degraded, and can indeed just swap your remaining new drive with the failed drive 1.
