I would like to add I have also seen this when using Ceph as a backend on a Pike deployment.
I have fixed several VMs, by performing the following process (note this can potentially wreck the VM, so be careful): Shutdown VM Create RBD snapshot (for backup purposes) Export the RBD disk as an image Then, setup the image as a loop device Run FSCK on the loop device Weirdly, a lot of times this wasn't enough, so I then had to: Mount the loop device on a (Ceph) host Umount the loop device Re-import the image back into Ceph, overwriting the existing image (or move existing, whatever) This then allowed me to continue booting VM as normal. I have tried using a recovery image on the VM and running fsck against the RBD device, but to no avail. Hopefully this may aid in investigation or help someone out.
