lost+found recovery
|
|
|
| Hello
After a crash that required fsck to be run on the root device
[/dev/md/rdsk/d10] I have a directory in the lost+found that appears to
be the '/' directory.
Can I fix this short of getting the backup tapes out?

That depends. If the files and directories within that directory
still have their original names, you can mv them back where they belong.
If they don't, restoring or reinstalling might be the only way.
Do you know what caused the crash? Was it bad software, or a power
failure, or is the hard drive dying?

Been a long time since I looked, but I never remember seeing named
files in a lost and found directory, just numbered files. ?

If a directory ends up in there, it will have a numeric name, but its
contents should still be the original names, just as the contents of an
ordinary file that ends up in there should be the old contents.

Yes the file are like #340678 I cd to this dir do a pwd and it's '/'.
I then do an ls and there you are in root.
Installing a patch caused the problem. On reboot I started getting
jnic1 errors that hung the reboot. Had to do a stop-a to get it back
then do a reset-all reboot from the ok prompt. Needed fsck ... rest is
not good.

Cool. I did not know that. I guess I've just been lucky enough not to
_need_ to know that...

You still have a root directory, otherwise where would /lost+found be?
Do /bin, /usr, /etc and other directories still exist? I'm just
wondering, could that file in lost+found be a symbolic link?

When you do a ls -l it does not list it as an link. And yes the system
is still running more or less OK.
