Hi,
There was some problem with our system so I re-installed the server with
CentOS 7. Now, when I am trying to run 'fdisk -l' command, it is returning
a broken output.
It throws this error- "fdisk: cannot open /dev/sdc: Input/output error".
There are valid /dev/sdd and /dev/sde devices which are mounted and they
are accessible but, somehow /dev/sdc is having a problem and 'fdisk -l' is
not returning the full output.
Below is an output of fdisk -l for reference. Any suggestion on how to fix
this would be very helpful.
