[OLUG] fsck is deleting my files

[Rogers, John C NWD02]

If fsck is deleting the files have you looked in lost+found to see if the
files are there?  UNIX does a really good job of tracking the files contents
and inode locations but if the system was synced then the file system may
have just lost the inode pointer to where the file was supposed be located.
If that is the case the file or any parts of the file end up in lost+found
at the root of the mounted file system.  Unlike Windog when a file is placed
in lost+found many times it is still useable unlike the infamous *.chk files
Mickeysoft creates that are actually useless.

Hope you find the files.
John

  Isn't there a sync called during a cron run on a regular basis? Why not
add one if there isn't ...
