Hi Gary,
before loosing any data, I suggest, to boot from a liuvefile linux. Please use
a modern livefile like Knoppix or Kali-Linux.
If it is not a BIOS problem, you should see the device again and are able to
mount it. If /root is on a seperated partition, you can do some filesystem
checks, like e2fsck or else.
Ans: Most important, with a livefile system you can mount an external harddrive
and backup all files. Thus , even when the /dev/nvme*** is died or partly
broken, you can maybe restore /root on another partition.
Second: Please check ACL, although I do not believe the reason for these, it
is worth to look at this. Maybe you or someone else has chenged it accidently.
Third idea: Is the harddrive full? In the past I has the problem, not to be
able to do anything. The reason: My harddrive was completely full (some
temporary file was the reason). Deleting this big file was the trick.
Just some ideas, maybe it could help.
Good luck!
Best
Hans
There is no problem seeing the root folder when I boot from a live distro.
fsck never finds any significant issue.
An ACL issue would be permanent. This comes and goes.
I actually doubled the size of the root device when I put in the new
NVME drive. When I set up the RAID array, I'd bought a 500G second drive
to mirror the 256G original drive. When I replaced the 256G drive, I was
able to expand the array to 500G (less a small amount for the EFI
partition). The partition has lots of free space.
As I said, running an fsck seems to fix the issue temporarily. I now run
an fsck on every boot.
