similar to: LVM not removing LV

Hi... I have had a problem when I am going to detach one specific LVM partitions of Xen, so I have been trying xm destroy <domain>, lvchange -an <lvm_partition>, lvremove -f.... So I haven''t had sucess. I restarted the server with init 1 yet and nothing... I have seem two specific process started xenwatch and xenbus, but I am not sure if this processes have some action over

Hi list, I'm having one of those 'I'm stupid' -problems with LVM on CentOS 5.2. I've been working with traditional partitions until now, but I've finally been sold on the theoretical benefits of using LVM, but for now I only have a huge pile of broken filesystems to show for my efforts. My scenario; I attach a disk, either over USB or iSCSI. I create a PV on this

I converted a system disk from a virtualbox VM and added to the config on a qemu VM. All seems well until I try to mount it. The virtual machine shows data for the disk image using commands like: pvs lvs lvdisplay xena-1 but there is no /dev/xena-1/root to be mounted. I also cannot seem to figure out whether the lvm related modules are available for the virtual machine kernel. Has anyone

Greetings - Ok, I made a mistake that I need to fix. Fortunately it is not a destructive mistake, but I need some advice on how to correct the problem. CentOS 6.3 host system named Earth I was creating some new logical volumes within my exiting volume group for a new virtual machine using the LVM GUI. When I created the LV that I plan to use for root partition of the new VM (Bacteria) I

We have about 800 CentOS 5.2 servers and our university. We use NFS being served from over 10 NetApp frames. We use autofs for to mount up our partitions. There have been times where we can't cd into the directory. It says the directory does not exist. On some servers it works but on others it does not. Typically we restart amd and autofs to resolve this issue. But sometimes it does not even

I know how to change the UUID of Physical Volumes and Volume Groups, but when I try to do the same for a Logical Volume, lvchange complains that "--uuid" is not an option. Here is how I've been changing the others (note that "--uuid" does not appear in the man pages for pvchange and vgchange for lvm2-2.02.26-3.el5): pvchange --uuid {pv dev} vgchange --uuid {vg name} Any

I have a virtual machine in a Xen LV, that I would like to backup from hostA to hostB because hostA is software broken. How do I copy and recreate that LV on hostB?

Hello, this is my first time posting on this mailing list. I wanted to suggest a addition to the qemu hook. I will explain it through my own use case. I use a shared LVM storage as a volume pool between my nodes. I use lvmlockd in sanlock mode to protect both LVM metadata corruption and concurrent volume mounting. When I run a VM on a node, I activate the desired LV with exclusive lock

Hi All I'm trying to setup my LVM thin pool to support discards so that the pool can reclaim space even if the underlying device doesn't support trim. It is my understanding that all thin pools should support trim even if the underlying device doesn't. (please correct me if I'm wrong here) I have one centos server that does support trim and everything is working correctly but any

OS: EL6 - sometimes I use kpartx -a /mnt/.../lvdisk.img to map the partitions and mount them via /dev/mapper/loop0pX After using the disk (unmounting it) I noticed that detaching such mapping via kpartx -d does not result in freeing up the loop devices. Results: System reboots shows that the filesystem where lvdisk.img is located can't be unmounted. lsof, fuser, ps does not show

Hello, I'm having a strange problem booting a new centos7 installation. Below some background on this. [I have attached the tech details at the bottom of this message] I started a new CentOS7 installation on a VM, so far all good, o/s boots fine. Then I decided to increase VM disk size (initially was 10G) to 13G. Powered off the VM, increased the vhd via the hypervisor, booted from CentOS

Hi, I just installed a CentOS 6.5 System with the intention of using thinly provisioned snapshots. I created the volume group, a thinpool and then a logical volume. All of that works fine but when I create a snapshot "mysnap" then the snapshot volume gets displayed in the "lvs" output with the correct information but apparently no device nodes are created under

Hi, I want to rename some volume groups and logical volumes. I was not surprised when it would not let me rename active volumes. So I booted up the system using the CentOS 5.5 LiveCD, but the LiveCD makes the logical volumes browsable using Nautilus, so they are still active and I can't rename them. Tried: /usr/sbin/lvchange -a n VolGroup00/LogVol00 but it still says: LV

I still get the "the discard operation is not supported" fstrim error when the LVs are set to "nopassdown" Seems that when I use ext4 the fstrim reports that it worked but the LVs Data% does not decrease after the fstrim. xfs just throws the error. I've also been looking at the output of lsblk -D # lsblk -D NAME DISC-ALN DISC-GRAN DISC-MAX DISC-ZERO xvdb
