You need to check the integrity of your data on the root file system when the following console output is returned:
Checking all file systems.
[/sbin/fsck.ext3 (1) -- /] fsck.ext3 -a /dev/vda3
/ contains a file system with errors, check forced.
/: Inode 226708 has illegal block(s).
/: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
(i.e., without -a or -p options)
To do this:
- Stop the instance and unmount the volume.
- Mount the volume on another instance.
- Run an fsck on the volume.
- Remount the volume on the original instance, then launch it.
