OK, I figured out a solution to the dreaded "Warning: inode_val:....." fiasco. This same issue has been plaguing my 2018 MB Pro for several months now, until now I finally had the time to dive it into the issue and created a resolution, I hope the below works for you all as well. Apple and Microsoft really need to get their acts together to create a patch for this problem, such a PITA complete loss users of data, information and time troubleshooting.
For starters, I am not certain what set this off to begin with but it appears to be 2 things possibly, some type of file or file name corruption within OneDrive which is also connected to drive imagery backup solutions such as TimeMachine and Carbon Copy, which I use all three, OneDrive, TimeMachine and Carbon Copy. When running Disk Utility from "Command-R" I would get the "Warning: inode_val:......" and also noticed that my 1 TB ssd was nearly maxed out with over 500 GB compromised by System Data, the highest System Data tapped out one day at 650 GB (See Below Screenshot).
My Troubleshooting: After multiple attempts and several variations of completely wiping my ssd and OS, starting with a clean install these were my results:
First Attempt: Command-R | wipe ssd and attempted back up from TimeMachine partition resulted in a completely failed restoration process, all TimeMachine back-ups were corrupted and would not work.
Second Attempt: Command-R | wipe ssd and attempted backup from Carbon Copy partition completed restored my device and all files but cloned the same corrupted files over from OneDrive resulting in the same "Warning: inode_val:....." error when running Disk Utility.
Third Attempt: Command-R | wipe ssd and this time did not connect and external Thunderbolt 3 devices, and conducted a fresh install of OS Mojave from the Apple Server. Presto! Warning: inode_val: problem solved, after booting up the the fresh OS install, I installed OneDrive waited for all files download, then restarted the machine, Command-R to run Disk Utility and boom no more errors. So in short, Do Not try and restore you machine from previous corrupted backup sources as this will bring the same corrupted files back to your new install. With the new installed I also recovered 75% of my compromised ssd storage. One final note, I am completely abandoning the use of TimeMachine, this is no longer a reliable or stable solution for file or system restoration.(See Final Screenshots)
Checking the fsroot tree
and additionally isThe volume /dev/rdisk1s1 appears to be OK
mentioned towards the end? PS. The warning may also already be present on your Time Machine backup. – Redarm Dec 19 '18 at 19:40
