Overview: We are running a Linux server with a Btrfs filesystem configured with multiple subvolumes and EFI-based boot. Recently, after a reboot, the server is failing to bring up network services—no network connectivity (no ping, no SSH access), and web services are not starting.
Current Situation: - The server’s root and Btrfs subvolumes are intact and accessible when booting into rescue mode. - Disk integrity and subvolume structure have been verified and appear healthy. - Network services do not start on normal boot, preventing remote access. - We have initiated a KVM console session to monitor boot-time behavior and gather logs.
What We Need: - An expert Linux system administrator with proven experience managing Btrfs-based servers and EFI boot environments. - Expertise diagnosing and resolving network initialization failures during system boot on such configurations. - Ability to analyze system boot logs, service statuses, and network configuration files (e.g., systemd-networkd, Netplan, NetworkManager). - Experience working with rescue environments, chrooting, and manual mounting of Btrfs subvolumes. - Capacity to develop, improve, and execute scripts for diagnostics and repair of complex boot and networking issues.
Responsibilities: - Analyze existing server configuration and logs to identify root causes of network failure at boot. - Verify and, if necessary, correct mounting procedures for Btrfs subvolumes during boot. - Validate and repair EFI bootloader configuration and files. - Inspect and troubleshoot network service configurations and startup procedures.
Ideal Admin: - Strong background in Linux system administration with deep knowledge of Btrfs filesystems. - Experience managing UEFI/EFI boot systems and GRUB bootloader configurations. - Familiarity with network configuration systems: systemd-networkd, Netplan, NetworkManager, or classic networking scripts. - Skilled in using rescue environments, chroot, and manual filesystem management. - Excellent problem-solving skills and ability to work independently with minimal supervisio
