Grabe. I did not expect that it will take 4 days to add 2x 10TB volume to my NAS.

I also realized the importance of UPS. Between adding the volume and completion, there was 20 seconds of electric interruption. That would have risk data corruption kung namatay yung NAS in the middle of the operation.
