    Hello All,

    I have a pretty stable FreeBSD 5.3-p5 production server which worked just
    fine - until today. I host over 100+ web sites on it (Apache + PHP4 +
    MySQL), email, ftp, etc. There was a time when it was up for over 6 months
    without a reboot. So it is stable. But today I had a strange problem with
    this server. I could ping it, but nothing else worked. I had to reboot it by
    plugging the power. After it came back, this is what I've found in the log
    file (and nothing else).

    It works just fine since the reboot. Not even fsck was needed (file system
    didn't get dirty by plugging the power???)...

    I've never seen this error message before. This could be an indication of
    what? A dying IDE hard drive???

    I happen to have an identical hard drive around here, unused. If I hook it
    up as a slave (IDE) drive, is there a way I can mirror the dying drive to
    the spare one (with all partitions, etc, intact)?

    Any help/comments would be appreciated. Please CC me, as I am not a
    subscriber of this list. Thanks!!!
