Volume Redundant
Not sure why but my last post disappeared without warning... however I'll try again.
I inserted a second disk into my 4 bay last night as I had been running on only one disk for some time.
This log came up:
Sep 27, 2018 05:59:00 AM Disk: Disk in channel 2 (Internal) changed state from RESYNC to ONLINE.
Sep 27, 2018 05:58:56 AM Volume: Volume data health changed from Degraded to Redundant.
Sep 27, 2018 05:58:50 AM Volume: Volume data is resynced.
Sep 27, 2018 01:00:37 AM Volume: Volume data is Degraded.
Sep 26, 2018 06:23:34 PM System: NTP is enabled.
Sep 26, 2018 05:54:24 PM System: Antivirus scanner definition file was updated to 58.24983.
Sep 26, 2018 05:37:48 PM Volume: Volume data health changed from Unprotected to Degraded.
Sep 26, 2018 05:37:43 PM Volume: Resyncing started for Volume data.
Sep 26, 2018 05:37:19 PM System: ReadyNASOS background service started.
Sep 26, 2018 05:37:16 PM Volume: Less than 30% of volume data's capacity is free. NETGEAR recommends that you add capacity to maintain current performance levels. Continuous protection snapshots will be deleted when volume free space is less than 5%.
Sep 26, 2018 05:21:55 PM System: The system is shutting down
Now everything is showing as healthy.... if it's healthy, what does redundant mean? Where to from here? Do I need to replace a drive?

RAID redundancy means that your volume is protected from an ordinary drive failure. In normal situations, your data will remain fully available even if one disk fails. So it is part of the healthy status, and you don't need to replace a drive.
But by saying "ordinary drive failure" and "in normal situations" I am pointing out that you can't depend on RAID as a backup. There are several scenarios where the RAID redundancy won't protect your data. You need at least one copy on another device to do that.
If you don't already have a backup plan in place, then that would be a good next step. The least expensive approach is to back up the files to USB drives. It is also possible to back up the NAS to cloud storage or to another NAS.

- Oh ok great thank you. Sorry if it was a dumb question. I tried to Google it and searched this forum but nothing was coming up explaining what it meant so I went on standard definition of the word. Thanks for explaining it. Appreciate it.
