(TS559 Pro currently on 3.6.0 B0210T. Upgraded firmware approximately one month ago, and have not rebooted since then).
After sitting idle for a couple of hours, I tried to access QNAP drive shares in windows and was unsuccessful (but was able to connect to web console). I could not see any disks under Volume Management or HDD S.M.A.R.T. I initiated a restart, but after almost half an hour the display on the QNAP still said restarting (and I was still able to access the web console). I tried to initiate a shutdown, but this did nothing either. I then turned off the QNAP using the power button, and after 30 seconds turned it back on.
The QNAP came back online, but I was still unable to access shares or see any disks in Volume Management or HDD S.M.A.R.T. I fired up an SSH connection with Putty, and ran the following:
