I need an experienced Linux system administrator to troubleshoot and fix boot issues on my CentOS 7 server hosted with OVH. The server is currently in rescue mode after a failed reboot. Here are the details of the issue: Server Configuration: CentOS 7. RAID 1 setup using /dev/md2 (root) and /dev/md3 (data). GRUB bootloader needs to be reinstalled and configured properly. Current Status: I can access the server via SSH in rescue mode. The RAID arrays are active and synchronized ([UU] state). /dev/md2 is mounted successfully, and the filesystem appears intact. GRUB is missing or misconfigured, causing the server to fail booting into normal mode. Problems Encountered: Attempting to reinstall GRUB (grub-install) results in command not found. YUM package manager cannot install grub2 due to GPG key issues and references to a deprecated repository (PLESK_17_PHP52). Some repository files are missing or misconfigured. What I Need: Proper GRUB installation and configuration for CentOS 7 on RAID 1 (/dev/sda and /dev/sdb). Fix YUM repository issues and GPG key errors to enable package installations. Ensure the server boots correctly from the hard disk (normal mode). Verify the integrity of the RAID setup and provide a summary of fixes applied. Access Details: Rescue mode SSH access provided by OVH. OVH control panel access if necessary to modify boot options. Requirements: Expertise in CentOS 7 and RAID setups. Experience with GRUB installation and bootloader troubleshooting. Familiarity with OVH rescue mode environments.

Hi, Upgrading from CentOS 7 to AlmaLinux 8 on a cPanel server is a complex process that requires careful planning and execution, so It is recommended to contact me first, to discuss the plan for the OS upgrade, Please DO NOT PLACE direct orders to avoid any confusion. cPanel & WHM version 110 will be the last version that supports CentOS 7. Support for version 110 will end June 30, 2024, so every user using Centos7 will have to migrate to an AlmaLinux 8 or CloudLinux 8 server before June 30, 2024. Important points to know before proceeding with the upgrade The OS upgrade is a critical task and involves the risk of downtime If the server will change then the DNS will also need to update and it may take up to 24 hours to reflect changes. Your server must have Centos 7 running on the server. Your server must have cPanel/WHM control panel installed You must have root user access to the server Your VPS/Server host should provide a tool/option to re-load the server with AlmaLinux 8 Server hardware and software should be compatible with AlmaLinux 8.
