I have a QNap TS-569 Pro configured with Raid 5 of 4 hard drives of 1 Terabyte each.
It has 5 disk slots and I want to increase the size of the Raid of another Terabyte.
Reading the manual seem pretty easy operation, but I have a doubt. After adding the new hard drive to the raid, the QNap will rebuild the raid.
During this time (usually it’s pretty long), can I access the data? Or would it be unavailable until the synchronization process finishes?
You can use the RAID array while it is being reshaped, but access will be slower than normal.
