I had the same problems as some others here - I was moving the data from a large USB drive to the DNS when the house lost power. From then on, I had one folder that did not appear on the DNS but whenever I tried to copy it again, I got an error saying the file/folder existed. Since I'm on a Mac, I poked around in the Terminal (Unix) and it's not there. So then I took everyone's advice and ran the disk check from the GUI. The disk failed.
So now I want to reformat it in Unix, and not deal with taking disks out and putting them back in and hoping I won't lose data. The Mac's Disk Utility won't see NAS devices.
The disks are single volumes, no RAID or JBOD involved.
I've looked all over the web and can't find a concise set of instructions. There's some info here and some info there, and some of it works and some doesn't (different flavors of Unix).
So what are the commands to look at the disks in the DNS unit to see what devices numbers, names, volumes, used space, free space, etc?
And then what are the commands to format a disk in the DNS and get it mounted and online?
This idea appeals to me more because you can see and control what commands work on what disks.
And you don't have to warn me - I know enough Unix to NOT be dangerous, I just never did this to a NAS before.
TIA
