Hi -- I forgot to remove an LVM snapshot after making a backup. Now neither the snapshot nor the original volume are available. How do I recover and get the original volume back online?

Hi -- I''m just a little nervous about deploying my Xen VMs. Will they perform when in actual production? How stable is Xen, really? So, I thought I would do some stress testing before deploying it. I''d like to test VMs running various services, alone and all together... DNS, HTTP/S, Tomcat, IMAP/SMTPD. Does anyone here have suggestions for load generating software? Or, has

I've been running into a reproducible problem when using default LVM volume group names to present block devices for virtual machines in KVM, and I'm wondering why it is happening. On dom0 I make a default VolGroup00 for the operating system. I make a second VolGroup01 for logical volumes that will be block devices for virtual systems. In VolGroup01, I make two lv's for one system:

On the subject of kernel updates: I had my install kernel (2.6.18-8.el5xen) and 2.6.18-8.1.8.el5xen on the box. I was unable to originally boot the update (8.1.8xen) because of the 3ware driver issues (I needed to use a driver floppy at install time). I jumped through some hoops (which I am struggling to understand) with weak-updates to get the 2.6.18-8.1.8 kernel to see my raid devices, which

Hi, I have a C5.8 machine with several DomU's. I fubared the fstab on one of them and I need to get it into single user mode. Does anyone know how to do that? I tried adding single to the extras line in /etc/xen/machine_name but it still tries to start in level 3. To make things worse, the root partition is on LVM. Alternatively, does anyone know how to access the image from DomU? I tried

Hi All, I am trying to create an initrd for a VM which uses LVM as its root partition. I am running the mkinitrd command a dom0 that also uses LVM - dom0''s volume group is "XenHost" while the VM''s volume group is "VG_VM10" (not sure if that matters). I issue the mkinitrd command from a chroot''d environment so I get the right /lib/modules &

First let me say that I'm not a sysadmin, but am simply wearing that hat this week so please excuse my ignorance. I need to temporarily move some virtual servers from a CentOS-KVM platform to a CentOS-XEN platform while I do some upgrades to the CentOS box.
