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

Hello All, updating from Centos7.3 to Centos7.4 rendered one of our laptops unbootable. EM: Failed to open \EFI\BOOT\grubx64.efi - Not Found Failed to load image \EFI\BOOT\grubx64.efi: Not Found start_image() returned Not Found How could this occur because of an update and how to fix this? What I tried is booting from centos usb, chroot to /mnt/sysimage and gave command: efibootmgr

hello there, I wonder if you could help me: I am trying to install 50 diskless servers using PXE / kickstart, it all starts well, DHCP server issues a dynamic address, tftp issues the kickstart file, the client starts reading the KS file but at some point anaconda brings up an unhandled exception related to Python when reading Comps.xml?? What is really unsettling is the fact that if I plug

This lays the groundwork for setting Root and RootBackup onto individual partitions for multiple disk installations in the future. Install, removal, upgrade testing has been performed and all seems to work at this point. --- scripts/ovirt-config-boot | 15 ++++++++------- scripts/ovirt-config-storage | 28 +++++++++++++++------------- scripts/ovirt-config-uninstall | 2 ++

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

The shim-x64 package installs its files directly to the EFI partition

Hello, I'm using a LVM storage pool. I renamed a guest and I would like to change the LV name to match to avoid future confusion. How do i do this? There is no vol-edit command (fully updated RHEL6). Thanks, Dax Kelson

I am running an Intel x64 machine using UEFI to boot an SSD. Installing the latest yum update which includes grub2 and kernel 4.18.0-193.14.2.el8_2.x86_64 renders the machine unbootable, blank screen where grub should be, no error messages, just hangs. After some hours I managed to modify another bootable partition (containing older software) and boot it from there. After that, I? found out

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

Hello all-- These instructions are somewhat OK but my messed up box is the only one I've got basically to help with this problem. Where can we find "correction" instructions using a "rescue" CD or flash drive? I understand RedHat provided detailed instructions to supported customers.

Hi, I was at the Puppet talk at Oscon and I would like to try using Puppet for PXE on RHEL machines and I was wondering if there are standard minimal Kickstart recipes from which Puppet can then take over. Thanks, Jason van Zyl jason at maven.org

This is a quick recovery and fix for the machines rendered unbootable after the grub2/shim yum update. It is written for CentOS 8.2.2004 but similar should work for any CentOS 8 or 7 as long as you get the correct shim file, that is, the one from the latest installation media. I am running on an x86_64 architecture (see uname -i). Please use the correct shim file for your architecture

Hi guys, sorry if this is trivial, but I have been googling a couple days and already compromised a test disk trying to figure this out, so I thought it is time to ask for some advice. I have a disk that comes from a clean and working CentOS4.2 install, and I am trying to use an external usb to ide converter to mount it on another workstation with CentOS4.2. I am trying this to better

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

Hey, Can anyone tell me why option 1 works and option 2 fails ? I know I need swap and such, however in trouble shooting this issue I trimmed down my config. It fails on trying to format my logical volume, because the mount point does not exist (/dev/volgroup/logvol) It seems that with option 2, the partitions are created and LVM is setup correctly. However the volgroup / logvolume was not

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.
