File system corruption running kernel 2.4.20-37.7.legacy (SMP)
Last modified: 2008-05-01 11:38:06 EDT
File system corruption after running kernel 2.4.20-37.7.legacy (SMP)
on a dual processor IBM x345. Several files became "invisible" unless
the system is booted in rescue mode from the install CD. "e2fsck -f" reports
no problems when run either from rescue mode or multiuser mode on new lernel.
One of these files is "/usr/bin/yum". From rescue mode, I can tar these
files, untar them to another file system, and the files are visible normally.
Attempts to create a file (as root) named "/usr/bin/yum" while running kernel
2.4.20-37.7.legacy (SMP) returns the error "permission denied".
This indicates two problems:
1. possible race condition in SMP file system code (hard to find)
2. insufficient consistency checks in "e2fsck" that do not detect this
error condition. (much easier to find)
As soon as time permits, I will run "fsdebug" against this file system,
and examine binary dumps of the directories involved in an attempt to determine
what inconsistency is not being caught by e2fsck.

AGGGHHHHH! NOT A BUG.
Some idiot had configured this machine to NFS-mount "/usr/bin" off another!!!!
When I helped with the upgrade, things worked fine until the last stages of the
Sorry to bother you..
