I have a LS-Q4 with four (4) 1TB drives in a RAID5 array. The array is 94% full, so I'm trying to increase the size of the storage. I took a 3TB drive out of the box and created a blank partition, then put it into slot 1, replacing the old 1TB drive. In NASNavigator, I logged into the NAS and went into Disk Management, then RAID Setup. I click on the tools icon next to the RAID array, which had a note that "An error has occurred" in the Disk Structure column. All 4 drives were properly listed. Disk 1, the new 3TB drive, was not checked. So I checked the box next to it and press the button to "Restructure RAID Array." The NAS went thru the process to rebuild the RAID array. It took less than a minute. Now, on the front of the NAS, all four drive lights are steady green. The status light is flashing. One (1) long red, then three (3) short red. It's been that way for hours. What does this mean, and how do I increase the size of the array. From reading the manual, this seemed like the way to do it.
