Files missing from filesystem? (2.4.9)

Files missing from filesystem? (2.4.9)

[Mark Cuss]

Hello all

I just upgraded the kernel on our server to 2.4.9 last friday.  We made some
changes to some script files that night, and discovered that the changes
were gone this morning.  A check of the backup tape that ran friday night
verifies that the changes were made, and a poll around the office yields
that noone changed them....

I had a dig through the kernel log and turned up the following message:

Aug 26 03:02:37 chaos kernel: (scsi0:A:0:0): Locking max tag count at 64

Does this have anything to do with it?  It seemed wierd to me - I had never
seen it before.  If anyone can enlighten me as
to what it means I'd really appreciate it.

Thanks

Mark

I looked through all the /var/log/messages files (actually all the files in
/var/log) and can't spot any bdflush entries.
This does however sound like it may be the suspect....  The machine has not
been down since these changes were made, so I figured that they would
"eventually" make their way to disk...  Perhaps I'm wrong.

Any other Ideas ?  :)

Thanks,
