Detailed Explanation

Install required libraries $sudo apt-get install libblockdev-crypto2 libblockdev-mdraid2 Todo Increase default timeout value sudo systemctl edit --full systemd-networkd-wait-online.service Change the following line, by adding "--timeout-10": ExecStart=/usr/lib/systemd/systemd-networkd-wait-online --timeout=10 If system include any watchdog settings in the BIOS? If such a hardware watchdog is enabled in BIOS, then you must either install the appropriate watchdog driver (which may be proprietary and only available for some distributions) or disable the watchdog Install packages sudo apt-get install libblockdev-crypto2 libblockdev-mdraid2 Verify /usr/lib/x86_64-linux-gnu/libbd_mdraid.so.2


Best Practices

  • 최신 버전 사용 권장
  • 공식 문서 참고
  • 테스트 환경에서 먼저 검증
