I have a degraded raid array (originally raid-10, now only two drives) that contains an LVM volume. I can see in the appended text that the Xen domains are there but I don't see how to mount them. No doubt this is just ignorance on my part but I wonder if anyone would care to direct me? I want to be able to retrieve dom-0 and one of the dom-Us to do data recovery, the others are of

I'm new to lvm. I decided to decrease the space of a logical volume. So I did a: $ df -m Filesystem 1M-blocks Used Available Use% Mounted on /dev/mapper/VolGroup00-LogVol00 1953 251 1602 14% / /dev/sda2 494 21 448 5% /boot tmpfs 1014 0 1014 0% /dev/shm

Hi. I'm currently trying to configure a kickstart script to do auto installs. We split up the partitions so that we have control on the mount security like setting no execute on the tmp portions etc . I keep hitting the same error : "Could not stat /dev/VolGroup00/LogVol_root --- No Such file or directory The device apparently does not exist; did you specify is correctly " Even

I have a centos 5.6 server that has xen domUs installed on their on logical volumes. These logical volumes contain their own volume groups and again their own logical volumes.

Hi People I just updated a CentOS 5.2 Server that is a Guest inside VMware ESX 3.50 Server using "yum update".

Does anybody here have any idea how to make an exact copy of a drive that has LVM partitions? I'm having trouble using dd to do this for an EL5 server. We're trying to diagnose a software problem of some kind and would like an exact, perfect copy of the software running so that we can see exactly what the problem is without disturbing our production copy. It's been admin practice

Hi, I have problems getting lvm to work on my domU. The dom0 is a CentOS 5 installed on lvm. I''ve added two extra lv, one for root and one for swap. [root@surr log]# lvscan ACTIVE ''/dev/VolGroup00/dom0vol'' [3.91 GB] inherit ACTIVE ''/dev/VolGroup00/dom0swap'' [1.94 GB] inherit ACTIVE

Not a centos specific question here, but if anyone can save me from shooting myself in the foot would appreciate any pointers.... I have an older centos 4.7 box that I recently replaced with a newer one running centos 5.3. I'd like to add the hard disk from the older one to the newer one before I scrap it for good. I don't care about the data on it, would just like the extra drive

I am trying to mount this (my old hard drive) from my Centos 5 install as a USB drive so I can copy files over. I have made the change to max_luns so that I can have more than one drive on a USB drive. The first partition, /dev/sda1 mounts automatically as /boot_ The second partition, /dev/sda2 is the one I really want and it is an lvm partition. When I am booted from this drive (as the

Hi, I have CentOS 5.0 which use an old hard disk. And recently I found there are some bad sector on it ... I try to backup my data to other CentOS 5.0 box .... What I did is. I remove the old HD (with bad sector) and install it as a slave IDE on a working CentOS 5.0 ... I try to mount the old HD as /mnt/oldDisk but since it's a LVM, the "mount -t ext3" doesn't work. I'm

I''ve spent the past while researching this but I''m just not finding a solution. I''ve been trying to get my xen kernel booting on a pretty much stock CentOS 4.4 installation. I installed Xen from src rpm and installed all the requisite software and I''m sure it''s with the ram disk but I can''t figure out how to resolve this. With a stock kernel

Hi all I have a remote server (i.e SSH access only) which was incorrectly partitioned and I urgently need to get it up and running. It's got a 500GB HDD, but the PV is only 10GB big, so I can't add more LV's to to. P.S. This is on LVM, btw.
