I keep get this and have not figured out why. I have restarted the node several times and this keeps happening.
the error messages look like critical disk failure or corruption. Do you have a recent backup?
No I have not done a back up.
If the disk hardware is bad you might have to start over with something else, if it is just the file system you might be able to flash StartOS onto a thumb drive and boot from it then recover → use existing drive
