Re: filesystem corruption with kernel built on Friday.

[Matthew Dillon <dillon@xxxxxxxxxxxxxxxxxxxx>]

:Hi All,
:
:My system was up and running from Friday (with a kernel built that day) to
:(roughly) about 15 minutes ago when all of a sudden my Diab cross-compiler
:(linux executable, nfs mounted fs) started segv'ing.
:
:At that point I figured it might be time to reboot so I cvsupped to pick up
:the latest changes and then checked out a new kernel. A strange thing
:happened though when I ran config... It gave me errors about files and
:directories not being accessible. I immediately rebooted, and ran config
:again, same errors. Ouch. Dropped into single user mode and started to fsck
:and it doesn't look good :( ...

    It's possible that the corruption is new, but it's also possible that
    the corruption is old.  e.g. the bitmap blocks could have gotten
    messed up prior to Friday.  Did you fsck your filesystems manually
    on Thursday or Friday?  Just rebooting would not have helped since a
    normal reboot doesn't cause a filesystem check to occur.

    I haven't had any corruption since the last major FP fix, which was
    on Wednesday.

    In anycase, what I recommend is that we try to nail down whether there
    is still a corruption issue or not, which means doing a manual fsck,
    making sure the kernel is totally up to date, and cleaning up the system.
    If any corruption reoccurs after that then we know we still have an issue.
