You should have posted this originally.

This tells you that dm-4 is being mounted ro to clean up orphaned inodes.

Do you know why it's remounting every morning?  Or why it unmounts 
before that?  If you can identify a reason the FS is being unmounted 
uncleanly you can probably fix the problem.  If the FS is cleanly 
unmounted, or unmounts itself, it's probably a hardware problem.  (You 
can run the vendor's diagnostics to verify that.)
