fsck.ext4(8) lists:
-p Automatically repair ("preen") the file system.
This option will cause e2fsck to automatically
fix any filesystem problems that can be safely
fixed without human intervention.
-y Assume an answer of `yes' to all questions;
allows e2fsck to be used non-interactively. This
option may not be specified at the same time as
the -n or -p options.
To see the difference you could download this[1], gunzip,
losetup and fsck with -p and -y.
The idea/concern is that we have some remote systems and
they generally do not have a serial console. So in case the
fs is corrupt the question is what to do. Currently the emergency
target would be entered but that will not help our users and
not us at all. The best I could think of is to just try to
fix whatever is broken and see if the system comes back online.
If it doesn't then it needs to be replaced, if it did we
might be lucky.
