Data Degraded Error
Hi,
I have just had a reboot and my system is giving a "Data Degraded" registering, I did get a "Disk 3 Error" and was about to backup and replace the disk when the "Data Degared' error occured.
Should I leave or shutdown and try to support rebuild?
Thanks,
Jim
Hi jimcocteau
The logs sent was before the disk was replaced right? What is the progress of the re-sync now? were you able to get the serial number of the replacement and the drive you replaced? Kindly PM me if it's available.
Re-sync once completed should get your NAS back to normal.
Regards

Hi jimcocteau
Data degraded means that a disk already failed/dead and it needs replacement.
It would be advisable to download the logs and check the health of the other disks, do a fuill backup and replace the failed drive so it will rebuild.
Data degraded status means that it will not be able to protect your data if another disk fails.
Hope this helps!

Hi Mark_V,
I have worked out I can replace the disk (I do have a spare, same size and type, it has been used in my other unit and will require formating when I install but should be fine. The logs are indicating disk three is the only one degraded so with my configuration as Raid5 with four disks I should be able to resync all files.
Can I just replace with out powering down?
Thanks,
jimcocteau
Hi jimcocteau
Yes, ReadyNAS supports hot swap so you don't need to power down the device when you replace a disk.
Please see How do I replace a disk in my ReadyNAS OS 6
Hope this helps!
