Problem booting that removes /opt to /lost+found
I have had a couple of really bad disk problems recently.
But I did not take a note of the disk error, so I will try to describe the symptoms.
/dev/hda6 mounted as / formatted reiserfs
System crashes and asks for the root password, I give this but then the system cannot find fortune and something else. It reboots.
I boot with knoppix.
reiserfsck /dev/hda6, it tells me to use the --rebuild-tree option
Once this has been done my entire /opt directory is in /lost+found. Copying all back to /opt cures the problem.
I cannot see any references in the logs.
