offline root lvm resize
So here goes... First some back story -Centos 5 with latest updates as of yesterday. kernel is 2.6.18-238.19.1.el5 -setup is raid 1 for /boot and lvm over raid6 for everything else - The / partition (lvm "RootVol") had run out of room... (100% full, things where falling appart...) I resized the root volume (from 20GiB to 50GiB). This was done from a fedora 15 livecd, seemed like a better idea than doing it on a live system at the time.... After the resize the content of all the lvs could be mounted an...

Boot fails with lvm snapshot

automatic repartitioning
Hello all. Does anyone have any suggestions for making centos cloud images that can automatically repartition the root device to resize the filesystem? All the Ubuntu UEC images do this, so using the same image, you can launch cloud instances of a variety of flavors and the VM instance will repartition the root disk and resize the fs. The Ubuntu images utilize scripts in the initramfs dpkg that

On an eight cpu system domU ''cap'' can only be set to 100
On a 8 Core system only dom0 can set cap > 100 and vcpus > 1. On a domU ''xm sched-credit -d <domU> -c 200'' says "Error: cap is out of range". Vcpu cannot be set higher than 1 - regardless of boot/config/command line. Low performance is equivalent to the cap setting. See ''xm list --long'': (domain (domid 0) (uuid
