Hi,
I started getting i/o error messages accessing this filesystem so I
rebooted the system. This might have been the wrong thing to do. This
subsequent boot went to maintenance mode due the filesystem's path being in
/etc/fstab.
I need some help with this please. Here is what mount says:
mount /dev/sda6 /opt.

for explanation
TLDNR: bad news, but btrfs experts may be able to help with recovery. The
article does
describe some information you should collect before asking for help. I
would add that
you should check the hardware: cables, drive S.M.A.R.T status. dodgy power
supply on
external drives, etc.
