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 have a CentOS-6.8 system which has a suspected HHD failure. I have booted it into rescue mode from a CentOS-6.5 minimal install CD in order to run fsck -c on it. The system hosts several vms. I have activated the lvs associated with these vm using pvscan -s ; vgscan ; vgchange -ay. An lvscan shows the lvs as ACTIVE. None are mounted. When I try to run fsck on any of them I see the

Hi, I am trying to set up a shared iscsi storage to serve 6 kvm hypervisors running centos 6.2. I export an LVM from iscsi and configured virt-manager to see the iscsi space as LVM storage (a single storage pool). I can create space on this LVM storage pool directly from virt-manager and I am already running a couple of sample VMs, that do migrate from one hv to the other. This configuration

Hi All, My CentOS 5.1 server is using iSCSI attached disks connecting to a dual controller storage array. I have also configured multipathd to manage the multiple paths. Everything works well, and on boot the dev nodes are automatically created in /dev/mapper. On these devices, I have created logical volumes using lvm2. My problem is that lvm does not recognize these iscsi/multipath volumes on

Hi all, Does anyone have a working example of creation of a logical storage pool and volume? I'm hitting a wall getting logical volumes to work on RHEL 6 beta. There's a single drive I'm trying to setup (sdc) as a libvirt managed logical storage pool, but all volume creation on it fails. Here's what I'm finding so far: Prior to any storage pool work, only the host

Hi I've recently rebuilt my home server using centos 7, and transplanted over the main storage disks It's a 3 disk raid5, with an lvm storage group (vg03) on there Activating and mounting works fine: # vgscan ? Reading volume groups from cache. ? Found volume group "vg03" using metadata type lvm2 # vgchange -ay ? 1 logical volume(s) in volume group "vg03" now

When the daemon starts up it creates a fresh (empty) LVM configuration and starts up lvmetad (which depends on the LVM configuration). However this appears to cause problems: Some types of PV seem to require lvmetad and don't work without it (https://bugzilla.redhat.com/show_bug.cgi?id=1581810). If we don't start lvmetad earlier, the device nodes are not created. Therefore move the

I renamed my volume with vgrename however I didn't complete the other steps. Mainly update fstab and intiramfs. Once I booted, I was dropped on the Dracut shell. From here I can see the newly rename VG and I can lvm lvscan as well as activate it, lvm vgchange -ay. However I can't figure out what to do next, I'm assuming I need to regenerate the initramfs and then boot to change

I either haven't searched for the right thing or the web doesn't contain the answer. I have used the following to mount an image and now I need to know the proper way to reverse the process. qemu-nbd -c /dev/nbd0 <qcow2 image using lvm> vgscan --cache (had to use --cache to get the qemu-nbd volume to be recognized, lvmetad is running) vgchange -ay

Hi, I have an iscsistorage which I attached to a new centos 6.3 server. I added logic volumes as usual, the block devices (sdb & sdc) showed up in dmesg; I can mount and access the stored files. Now we did an firmware software update to that storage (while unmounted/detached from the fileserver) and after reboot of the storage and reatache the iscsi nodes I do get new devices. (sdd &

I have an 8-core SuperMicro Xeon server with CentOS 6.3. The OS is installed on a 120 GB SSD connected by SATA, the machine also contains an Areca SAS controller with 24 drives connected. The motherboard is a SuperMicro X9DA7. When I installed the OS, I used the default options, which creates an LVM volume group to contain / and /home, and keeps /boot and /boot/efi outside the volume group.

With XCP how do we autostart a VM when a host boots up? In Xen I would have made a symbolic link to the VMs config in /etc/xen/auto/ Also does anyone know why LVM is disabled in the /etc/rc.d/rc.sysinit in XCP 1.1 beta? I uncommented it and when my Host boots it does a vgchange -ay now and the LV gets mounted in the fstab. I can''t think of a reason why this isn''t the default

Get a CentOS Install media , boot from it and select troubleshoot.Then mount your root LV, boot lv , /proc/, /sys, /dev & /run (last 4 with "bind" mount option).Then chroot into the root LV's mount point and then change grub menu and run "dracut -f --regenerate-all" last step is to reboot and test.

Hi, I am trying to recover data from my old system which had LVM. The disk had two partitions - /dev/sda1 (boot, Linux) and /dev/sda2 (Linux LVM). I had taken a backup of both partitions using dd. Now I am booting of CentOS live cd for system restore. I recreated partitions like previous system using fdisk and then used dd to dump all the data onto it. I would like to mount sda2 as LVM, but I

I've created my storage pool incorrectly. I'm using LVM and I have a volume group called vms-lvm. When I look at it in virt-manager I see that the volumes it contains are home, root and swap, so when I created the storage group in virt-manager I must have specified something incorrectly. Unfortunately I can't find a way to correct this. If I try to destroy (stop) the storage group I
