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).

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!!! Zoltan
