    Hint for anyone else coming across this: run dmesg, it may give you more information on what your problem actually is. Commented Oct 1, 2019 at 15:53
  • To add to the suggestion by @WinstonEwert, run dmesg without piping it to grep. The messages I needed to see had no mention of my device, label, or mount point (other than dm-0 which I was not looking for)! Commented Sep 18, 2020 at 20:00
  • dmesg told me I had "default" in /etc/fstab, "unrecognized option", when it should have been "defaults". Commented Jul 20, 2021 at 6:03

    If you came to this question through a search, but your problem involves NFS, see NFS does not work. mount: wrong fs type, bad option, bad superblock. Commented Jun 13, 2022 at 17:46
  • I added a new drive to the server and I accidently swapped the SATA cables from some drives. That was the problem for me. Switched them back to the way they were and it was all fixed. Commented Aug 1, 2022 at 18:55
