我最近从 ubuntu 16.04 升级到 18.04.1，遇到了一些问题。为了尝试一些事情，我启动了一个全新的 VM，安装了所有更新并安装了我的媒体共享。然后我尝试启动 plex 媒体服务器，但失败了，并收到以下错误：
Sep 26 15:05:44 plex rsyslogd[1053]: file '6' write error: No space left on device [v8.32.0 try http://www.rsyslog.com/e/2027 ]
Sep 26 15:05:44 plex rsyslogd[1053]: action 'action 3' (module 'builtin:omfile') message lost, could not be processed. Check for additional error messages before this one. [v8.32.0 try http://www.rsyslog.com/e/2027 ]
Sep 26 15:05:44 plex rsyslogd[1053]: file '6' write error: No space left on device [v8.32.0 try http://www.rsyslog.com/e/2027 ]
Sep 26 15:05:44 plex sudo[1895]: pam_unix(sudo:session): session closed for user root
Sep 26 15:05:49 plex sudo[1898]: plex : TTY=pts/0 ; PWD=/dev/mapper ; USER=root ; COMMAND=/bin/journalctl -xe
Sep 26 15:05:49 plex sudo[1898]: pam_unix(sudo:session): session opened for user root by plex(uid=0)
然后我检查了我的文件系统：
plex@plex:/dev/mapper$ df -h

据我所知，两个卡扣式安装座都应该使用 100%。这是映射器造成的吗？
通过 Google 搜索该问题，我发现了没有任何剩余 inode 的可能原因，因此我检查了：
plex@plex:/dev/mapper$ df -i

我是否遗漏了什么？
谢谢你的帮助！
答案1
您的根文件系统只有 4GB 并且已满：
/dev/mapper/ubuntu--vg-ubuntu--lv 3.9G 3.7G 0 100% /
答案2
如果您的卷组中还有剩余空间（使用 vgs 检查），则可以将一些空间添加到您的完整逻辑卷中：
lvextend -L +2G /dev/mapper/ubuntu--vg-ubuntu--lv
resize2fs /dev/mapper/ubuntu--vg-ubuntu--lv
