On 01/06/21 aida-3 was rebooted as the graphical user interface had frozen.
We were also unable to connected to MIDAS via ssh port forwarding.

Since the restart we have been unable to write to file.

The tapeserver will allocate/mount/open a file but nothing will be written to it.
The merger will be receiving data but never shows as having any "Current links with data".

/MIDAS currently points to lrwxrwxrwx. 1 root root 45 Jan 23  2019 /MIDAS -> /home/npg/MIDAS_Releases/23Jan19/MIDAS_200119
