Hi, I have a system running CentOS4.8. Last month I installed the latest updates including kernel 2.6.9-89.0.23 and rebooted the system. It has been running for almost a month. Last night I updated the system again which updated only a few packages: openssl, tzdata, curl,vixie-cron and logrotate. No new kernel or anything out of ordinary. The reboot after the update stopped with kernel panic: --<snip>-- Loading dm-snapshot.ko module Making device-mapper control node Scanning logical volumes Reading all physical volumes. This may take a while... Activating logical volumes Volume group vg00 not found ERROR: /bin/lvm exited abnormaly! Creating root device --<snip>-- After that it's trying to mount root and it fails with kernel panic. This system is using disk partitions. It's not using LVM. I can boot in rescue mode and "chmod /mnt/sysimage". All partitons are there and mountable. No fsck errors. I checked /boot/grub/grub.conf and it looks fine to me. The time stamp was from last month when I did the first update. Also there are no new files in /boot since the update from last month. Why is it looking for logical volumes? Any idea? Thanks Peter
