Googling got me the command: /sbin/mkinitrd -f /boot/initrd-$(uname -r).img $(uname -r) Unfortunately this resulted in: error opening /sys/block: No such file or directory error opening /sys/block: No such file or directory The renamed root lvm filesystem is mounted on /mnt/root the /boot is in /dev/sda1 and mounted on /mnt/root/boot before doing the chroot, I tried sudo cp -a /sys/block /mnt/root/sys Even though it was done with root privilege I got a lot of read permission errors, but a lot stuff did copy, maybe I got what I need. did the mkinitrd, no errors Lets try booting from the hard drive. Hmm there's a splash screen, that's a good sign. No Joy. It's not booting and complaining about not finding stuff with the old names. Did I screw up the grub.conf edits. Just checked they are ok. It finds the volume groups with the new names then complains about the old names: Volume group "VolGroup00" not found Unable to access resume device (/dev/VolGroup00/LogVol01) Hmm. That's the old name of the swap device. There's at least one more piece of the puzzle that's missing. Lets boot up the Live CD again. And take a closer look at fstab.

[CentOS] No live migration for xen virtual machines any more
Hi folks, I have upgraded my CentOS RHCS cluster hosts to the recent packages, and now live migration of the xen virtual machines does not work any more: [r...@node ~]# clusvcadm -M vm:XenVM -m othernode Trying to migrate vm:XenVM to othernode...Invalid operation for resource I have googled the net but found no recent entries for that problem, just older posts. Has anyone had the same problem recently? If yes: is there any workaround? Any hint or help is appreciated.

Well, yes, my sendmail.cf is configured via sendmail.mc... which makes it
pretty easy... there will be an authenticated handling process in
sendmail.cf that sendmail.mc inserts automagically...
e.g.
# authenticated?
R$* $: $1 $| $>"tls_client" $&{verify} $| MAIL
R$* $| $#$+ $#$2
R$* $| $* $: $1
R<> $@ we MUST accept <> (RFC 1123)
R$+ $: $1
R<$+>$: <@> <$1>
R$+ $: <@> <$1>
R$* $: $&{daemon_flags} $| $1
R$* f $* $| <@> < $* @ $- > $: < ? $&{client_name} > < $3 @ $4 >
R$* u $* $| <@> < $* > $: < $3 >
R$* $| $* $: $2
