After reformatting a disk that I think had nothing to do with the Fedora installation, it now boots always in emergency mode, no matter what "Fedora" option I choose in the bootloader

My disk configuration: I have 3 500GB disk in an array with Intel Matrix Storage. The array was split in 2 disks. One of them, Raid 0. Fedora (home, root, swap) are partitions of this disk (they aren't the only ones). The other disk in the array used to be Raid 5. I changed it to Raid 0 and formatted it to NTFS from Windows. After that, I can't boot Fedora. Windows is on a separate 1TB disk.

In the journal log, I see "red stuff" including:

  • tsc: fast tsc calibration failed
  • Failed to find module 'vboxdrv'/'vboxnetflt'/'vboxnetadp'
  • Failed to start Load Kernel Modules
  • inotify_add_watch(7, /dev/sda2, 10) failed: No such file or directory
  • inotify_add_watch(7, /dev/sda4, 10) failed: No such file or directory
  • inotify_add_watch(7, /dev/sda3, 10) failed: No such file or directory
  • inotify_add_watch(7, /dev/sda1, 10) failed: No such file or directory
  • [sdi] No Caching mode page found. Assuming drive cache: write through
  • Dependency failed for Mark the need to relabel after reboot

Clearly I have no idea which of these errors where already there when the PC worked normally. The /etc/modules.load.d folder is empty (not sure if it should be)

Thanks for the help

    Wait, RAID 0 is normally a way to combine multiple disks together where performance is all that counts; data is not redundant in any way. – derobert Jun 6 '14 at 22:21

  • Up to know, all I did was fiddle around with fsck. Also yumremoved Virtual Box but the vboxdrv/etc errors didn't stop (why is VB so important that I haven't even logged in and it already tried to load its modules? I never even used it yet) – Rojo Jun 6 '14 at 22:31
  • Fedora 20 is long out of maintenance. If you need long life, migrate to e.g. CentOS. – vonbrand Dec 27 '15 at 16:26

All solved. In the /etc/fstab file, it was trying to mount a partition that isn't there any more. It seems it considered this bad enough to enter emergency mode!

    Any tips for someone who only has /dev/mapper/fedora-root / and /dev/mapper/fedora-swap swap? I can't seem to figure out how to make it boot solidly. – Seiyria Aug 3 '14 at 15:28
  • Just had the same issue with fedora 24 after removing a secondary disk that was mapped from /etc/fstab. Thanks for the fix. – Tiksi Sep 15 '16 at 10:24
