similar to: change HVM to PV with root on logical volume

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. I've created a local LV, and used DD and SCP to transfer the block device from the VKM machine to the XEN machine. For quite a

I have searched the list, and don't see this covered or didn't search for the right words. I'm running CentOS 4.8 and have some DVD's for 5.4. I have a lot of customized and additional software installed and would like to avoid starting over with a scratch install. After the upgrade from the DVD I would do a yum upgrade to 5.5. Is this a workable (and safe) thing to do? What

I created a 1TB RAID1. So far it is just for testing, no important data on there. After a reboot, I tried to mount it again # mount /dev/mapper/vg00-btrfsvol0_0 /mnt/btrfs0 mount: wrong fs type, bad option, bad superblock on /dev/mapper/vg00-btrfsvol0_0, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or

hello all, Hoping for some help on copying Logical Volumes. I would like to copy an existing LV to a newly formed LV. I don't want to do a snapshot of an existing LV. Only way I've seen is to mount the to LV and: mount /dev/vg00/lv00 /mnt/orig mount /dev/vg00/lv01 /mnt/copy cd /mnt/orig tar cf - ./ |(cd /mnt/copy; tar xf - ) Is there a LV tool to do this? Or an option used with

I tried to start a linux hvm domain (just for testing some things compared to a pv domain), and it didn''t start up. I then did a ''xm shutdown'', which didn''t work, then a ''xm destroy'', and from then the ''xm list'' function just hung. I then restarted xend, and ''xm list'' works, but now when I try to start the

I am trying to install CentOS from an ISO image file but the installer does not see a CD-ROM drive. The VNC viewer works but the CentOS installer indicates "Unable to find any devices of the type needed for this installation type." Then it prompts with "[Select driver] [Use a driver disk] [Back]". I have tried several variations of the "disk" paramater, all

I did something stupid when setting up a server which is now live. I think I'm stuck. I set up swap on Raid1 which is decidedly non-optimal. I'd prefer 2 independent swap partitions at the same priority. Here is the set up: /dev/sda1 + /dev/sdb1 -> md0 (raid1) md0 -> VolGroup00 VolGroup00 -> VG00LV00(/), VG00LV01(/home), VG00LV02(swap) I've gotten as far as : Turning

Hi, As someone new to puppet I''m trying to work out the best way to manage different filesystems and logical volumes on different servers. Specifically I would like to be able to define on a series of nodes different LVM logical volumes to create and mount. I''m trying to do this at the moment with a define of the following type: # Manage a partition and create if needed.

I am running a Debian Squeeze Xen 4.0.1 Hypervisor and 2.6.32-5-xen-amd64 dom0. My xen-tools.conf: lvm = vg00 size = 100Gb # Disk image size. memory = 2048Mb # Memory size swap = 2G # Swap size # noswap = 1 # Don''t use swap at all for the new system. fs = ext4 # use the EXT3 filesystem for the disk image. dist = `xt-guess-suite-and-mirror --suite` # Default

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 &

I have an smbd process that is using alot of cpu on HP-UX 11.11 using Samba 2.2.3a. It looks like the application on the client side is trying to open and close a ton of files, many of which do not exist. When I do a trace on the smbd process, I see repeated calls to lstat64 to what looks like all of the device files on my unix server. Here is a little bit of the trace. It goes through all of the

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi list, I have an IBM xseries 345, running CentOS 5.3, hosting a few Xen domUs. However, I need more RAM -- but cannot remember if all (four) RAM sockets are populated (which would mean to buy higher capacity modules) or if there are two slots left to use. However, I'd like (and think that it's possible, but don't remember how) to

Hi All, [I originally posted this message in the main CentOS users' list, but later found this list. So, I'm reposting it here since this is where it belongs.] I'm trying to install a Fedora 8 domU on a CentOS 5 dom0, but the following command fails: [root at xenmaster ~]# virt-install -p -n krs -r 512 -m 00:16:3E:66:94:5F -b xenbr0 --vnc --vncport=5910 -l

Hello, It's me again with one more misunderstanding of libguestfs usage... Guestfish (as well as python libguestfs module) refuse to mount logical volume containing the root partition of the VM's filesystem. According to this short guide<http://rwmj.wordpress.com/2009/04/07/libguestfs-lvm-support/> I am trying to mount /dev/vg_kojit/lv_root as "/", but nothing works:

Came across a strange problem, I have a software raid1 with LV sitting on top. When I try to mirror an existing LV to a new LV with the tar command I get these error messages. mount /dev/vg00/base.centos /mnt/orig mount /dev/vg00/test /mnt/new cd /mnt/orig tar cf - ./|(cd /mnt/new; tar xf - ) ...

I am having an issue with Megacli when adding or removing virtual disks. I will post a link to fpaste that has the issue shown. In brief whenever i add, or remove, a virtual disk via MegaCli the attempt succeeds and the adapter is configured but the OS remounts dm-0 in read only. dm-0 is my root lv. This issue does not happen if i boot into the default, non Xen, CentOS kernel. On stock

Hello, Maybe someone can help me.... I have a guest XEN image that ran well until today. I use an LVM partition to host the guest and today on Dom0 I added another LVM to be available to this domU. This were all the commands I issued : On hypervisor lvcreate -n lintra02data -L 30G rootvg vi /etc/xen/lintra02 and add volume to file like this : disk = [

I installed CentOS on my home-server with 2 IDE 160GB MAXTOR HDD / RAID-1, LVM and ext3 partitions. Previous OS on this machine was FC2. I often "play" with LVM and, sometimes, have to extand or reduce some volumes size. I was surprised to see that resize2fs isn''t included anymore ! The replacing tool is ext2online but this one seems to only be able to grow a filesystem (not

I have a machine with two swap partitions (sda2 and sda8). Both will have none as mount point. When I try to use puppet (using mount type) for managing fstab I get problems because "name" in both instances (i.e. mount path) will be "none". How should I fix this within puppet? Regards Halvard Moe
