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 ...
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.
If the volume doesn't get mounted as degraded with just the remaining drives when you re-boot, then it is unlikely that it wiull do so with a replacement drive.
Well after i replaced the bad drive and the resync finished it showed that the volume was healthy and no longer degraded and all data was still there.
The only issue remaining is that my single X-Raid volume is still not there and i have 3 Raid Groups showing instead. When i click on the Xraid button to the right it says "You are attempting to switch from Flex-Raid to X-Raid. This is not possible becuase you have expanded volumes.
So i'm still not sure how i got to here with the Raid groups and being on Flex-Raid instead of X-Raid but does anybody have any ideas how to get it back to a single X-raid volume before i do a last resort of destroying the volumes and making a new one again?
Thanks.
