(Ubuntu 19.04) NFS 共享不會在啟動時自動掛載:‘mount.nfs: Network is unreachable’
我不知道如何在啟動時掛載 NFS 共享。我嘗試了幾種不同的方法(如下所列),但沒有任何效果。在這兩種情況下,他們都需要
network-online.target
,但他們似乎並沒有在開始之前等待網路上線。是的,我確實可以與遠端機器通信,mount -a
登錄後我可以執行,共享將被掛載。我完全不知所措。嘗試#1:我將以下內容放入
/etc/fstab
:10.0.10.10:/volume1/Media /mnt/media nfs x-systemd.automount,noauto,nofail,x-systemd.requires=network-online.target,suid,dev,exec,rw,sync,nouser 0 0
重啟後的結果:
root@ubuntu-svr:~# journalctl -b -u mnt-media.mount -- Logs begin at Mon 2019-08-12 00:00:56 UTC, end at Fri 2019-09-20 22:05:16 UTC. -- Sep 20 21:36:29 ubuntu-svr systemd[1]: Mounting Mounts the '/mnt/media' directory... Sep 20 21:36:29 ubuntu-svr mount[1528]: mount.nfs: Network is unreachable Sep 20 21:36:29 ubuntu-svr systemd[1]: mnt-media.mount: Mount process exited, code=exited, status=32/n/a Sep 20 21:36:29 ubuntu-svr systemd[1]: mnt-media.mount: Failed with result 'exit-code'. Sep 20 21:36:29 ubuntu-svr systemd[1]: Failed to mount Mounts the '/mnt/media' directory.
嘗試#2:我註釋掉了 fstab 條目並創建了一個 systemd mnt-media.mount 文件並啟用了 systemd 單元以在啟動時啟動。這是
mnt-media.mount
文件的內容:root@ubuntu-svr:~# cat /etc/systemd/system/mnt-media.mount [Unit] Description=Mounts the '/mnt/media' directory Wants=network-online.target Requires=network-online.target #After=network-online.target [Mount] Where=/mnt/media What=10.0.10.10:/volume1/Media Options=auto,x-systemd.automount,nofail,suid,dev,exec,rw,sync,nouser Type=nfs [Install] WantedBy=multi-user.target
我通過
systemctl enable mnt-media.mount
. 我重新啟動,並檢查了它的狀態:root@ubuntu-svr:~# systemctl status mnt-media.mount ● mnt-media.mount - Mounts the '/mnt/media' directory Loaded: loaded (/etc/systemd/system/mnt-media.mount; enabled; vendor preset: enabled) Active: failed (Result: exit-code) since Fri 2019-09-20 22:28:51 UTC; 1min 12s ago Where: /mnt/media What: 10.0.10.10:/volume1/Media Sep 20 22:28:51 ubuntu-svr systemd[1]: Mounting Mounts the '/mnt/media' directory...

Sep 20 22:28:51 ubuntu-svr systemd[1]: Failed to mount Mounts the '/mnt/media' directory.
解決了:
原來我需要啟用該
systemd-networkd-wait-online.service
服務。現在我嘗試的兩種嘗試(/etc/fstab 和 mnt-media.mount)都按預期工作。對於其他為此苦苦掙扎的人,取決於您是否使用
systemd-networkd
orNetworkManager
,您需要確保您的系統上啟用了systemd-networkd-wait-online.service
or 。NetworkManager-wait-online.service
否則,即使您的掛載明確需要,您的系統也不會等待網路啟動。我通過這個連結找到了這個答案:NFS/Troubleshooting - Network is unreachable。
