Rebooted to Degraded Volume and RAID Groups appeared without XRaid
Hello I have a RN428 with Firmware 6.9.3 which has 2x6TB, 2x4TB, and 2x3TB disks installed in that order with a single data volume which was in X-Raid and working just fine. I just backed up ...
The top priority now is to make sure you have a full backup. Your data is at risk.
Fixing the volume issues you are seeing is tricky, and there is no step-by-step available for it. It's safest to use paid Netgear support to troubleshoot and fix it.
If all the messages are related to sda, then disk 1 is misbehaving. Possibly it needs to be replaced - hard to say w/o looking at the full logs. But simple replacement might not be enough.
If you do want someone to look at the logs, then send a private message (PM) to one of the mods ( JohnCM_S or Marc_V ) asking them to take a look. Include a link to this thread. You can't attach the log zip, so you'll also need to upload it to cloud storage (dropbox, google drive, etc), and include a download link. Don't post the logs publicly.
You send a PM using the envelope icon in the upper right of the forum page.
Thank you for the response. I do have a backup luckily as i just finished it prior to the reboot.
All the messages in the kernal.log do appear to all be sda but to me its strange that the smart and disk info show no errors or anything for that disk.
I will try to PM the log files to the users like you suggested to see if anymore can be determined. I guess my last resort is to factory reset the device and rebuild the X-raid single volume and restore all the data and see if that helps me. I'm just concerned that these messages may mean that the controller in the NAS unit is failing or something like that.
Thanks
Craig.
There is no raid controller in the ReadyNAS. It is all done with software raids (mdadm). Essentially, it is the exact same as a standard PC with 8 HDD bays and in a different form factor of course.
Well i pulled out sda and ran some WD lifeguard dianostics on it which did come back with a fail status on the extended test. So I have ordered a replacement for the drive.
When it comes I guess i'll see if i can just pop it in and it will rebuild the xraid array or if the three raid groups will stay there for some reason. If it doesn't go back to xraid i guess i'll have to wipe the volume and create a new fresh one.
