Hi,
I am new to this forum so please forgive me if this is under the wrong topic. I moved my home office and I had the tunderbay attached to a battery backup that was controlled by my Mac. (It is now plugged into a port that never shuts down) When the mac shut down at night, it shut off the tunderbay and I received this message: Do I need to replace all of my drives? I can still access my files.
Thanks for your help!
Chances are you got errors from the shutdown.
If your volume was in sync before this happened, then do the following:
Clear any io errors on the disks or volume.
"recover failed disks" and let it rebuild (in the background)
If optimization is set to audio/video, change to workstation.
I plugged in a usb card reader and my Thunderbay 4 gave me the degraded failed message across all of my drives. I ran a Validation over night and it came back ok. I cleared the I/O Errors on all of the drives and the main volume and restarted the Mac but I can't get rid of the degraded - failed message on the volume. Each of the disks now say no errors on their own, but when I click on the volume they each say data and parity disk - failed. It seems to be running fine now, but I am still concerned about the error messages.
Is there more I should do to resolve the issue or how do I clear the error message on the Volume?
Since the Validate succeeded, the volume is validated and in sync.
So you can safely use "recover failed disks". Its up to you whether you re-validate or not.
