Boot failure stating: root: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
If a Unitrends appliance fails to start and a file system error is displayed in the hypervisor client console (or onscreen for physical appliances), on reboot the appliance will need a manual file system check (fsck) to correct the problem.
An example file system error is displayed, below:
root contains a file system with errors, check forced.
Inodes that were part of a corrupted orphan linked list found.
root: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
*** An error occurred during the file system check.
*** Dropping you to a shell; the system will reboot
*** when you leave the shell.
This issue can result from improper shutdowns of the appliance for hard resets, power failures, hard disk errors etc...
