We see:
-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. If e2fsck
discovers a problem which may require the system administrator
to take additional corrective action, e2fsck will print a
description of the problem and then exit with the value 4 logi-
cally or'ed into the exit code. (See the EXIT CODE section.)
This option is normally used by the system's boot scripts. It
may not be specified at the same time as the -n or -y options.
OK but also mention that some items will be also printed along with
"IGNORED" and exit value 0.
# fsck -C -V -f -a /cf
fsck from util-linux 2.28
[/sbin/fsck.ext4 (1) -- /mnt/usb/cf] fsck.ext4 -f -a -C0 /dev/sdc2
Inode 65395 extent tree (at level 1) could be shorter. IGNORED.
/dev/sdc2: 914/128016 files (1.4% non-contiguous), 73617/512000 blocks
To fix them one must use e.g., -y.
If one does not fix them they will just be printed the next time.
