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 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

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'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 ?

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 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.

Have you tried to use NetworkManager ? After all ,anything network related should be done by it. [root at system ~]# nmcli connection add con-name dummy0 ifname dummy0 type dummy ?

Hi all, One of our Dell servers has failed badly, and one of the domU's has been corrupted in the process. It boots up to a point and then gives me a kernel panic: Loading dm-zero.ko module Loading dm-snapshot.ko module Scanning and configuring dmraid supported devices Scanning logical volumes Reading all physical volumes. This may take a while... No volume groups found Activating

Hi David, Also consider using the mount option to specify backup server via 'backupvolfile-server=server2:server3' (you can define more but I don't thing replica volumes greater that 3 are usefull (maybe in some special cases). In such way, when the primary is lost, your client can reach a backup one without disruption. P.S.: Client may 'hang' - if the primary server got

I guess you didn't receive my last e-mail. Use getfattr and identify if the gfid mismatch. If yes, move away the mismatched one. In order a dir to heal, you have to fix all files inside it before it can be healed.

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

Requirement is a very strong word , but you should consider using it and here is a short demo why: - By default, RHEL uses NetworkManager to configure and manage network connections, and the /usr/sbin/ifup and /usr/sbin/ifdown scripts use NetworkManager to process ifcfg files in the /etc/sysconfig/network-scripts/ directory. [root at system ~]# ls -l /usr/sbin/ifup lrwxrwxrwx. 1 root root 22 21

I've touched the directory one level above the directory with the I\O issue as the one above that is the one showing as dirty. It hasn't healed. Should the self heal daemon automatically kick in here? Is there anything else I can do?

Hi all, I need to add a drive with the same LVM labels (i.e. system) to a machine with a drive with the same label. How can I access the data on both drive's LVM partitions at the same time? -- Kind Regards Rudi Ahlers

Hello Community, my name is Strahil Nikolov (hunter86_bg) and I would like to update the following wiki page . In section "Create the New Initramfs or Initrd" there should be an additional line for CentOS7: mount --bind /run /mnt/sysimage/run The 'run' directory is needed especially if you need to start the multipathd.service before recreating the initramfs ('/' is on

Anyone have any ideas? It's rather annoying that I can't get these to persist across reboots without using some kind of helper script.

No. Network Manager is always disabled on our builds since at least Cent5 days. The network stack has always been able to be managed properly without relying on Network Manager. Is that now an absolute requirement? It never has been prior.
