Hi Mark, Would you mind to elaborate your steps of fixing? I'm using 'yum groupinstall --installroot=/<loopDevice> ...' method, then Install(not update) the newest kernel from cr/ repository. Did you rebuild initial ramdisk? If so, what's your command to do that? Thanks a lot. --Rob ________________________________ From: "m.roth at 5-cent.us" <m.roth at 5-cent.us> To: CentOS mailing list <centos at centos.org> Sent: Wednesday, November 23, 2011 11:47 AM Subject: Re: [CentOS] Any ideas?? -- Re: EC2 compatible kernel for centos 6?

FUNNY you should mention that... I literally ran into that yesterday, with lots of screaming and yelling. This will sound scary, but isn't: try reinstalling, but when you get to the screen that asks you what you want to do, select the radio button for "upgrade", which says it does *not* format the partition(s). I did that - I had rsync'd / and /boot from another server, identical, with Linux software RAID. Bad mistake - best guess is there are some magic numbers in initrd - so I did this. It only took a couple of minutes, and seemed to not do much more than reinstall grub and some post-install scripts, and everything was wonderful. mark _______________________________________________ CentOS mailing list CentOS at centos.org http://lists.centos.org/mailman/listinfo/centos
