httpd:设备上没有剩余空间

httpd:设备上没有剩余空间

我正在使用 Fedora 17,在过去的几天里我的系统遇到了问题。每当我尝试启动时,httpd它都会向我显示:

Error: No space left on device

当我执行时systemctl status httpd.service,我收到以下输出:

httpd.service - The Apache HTTP Server (prefork MPM)
          Loaded: loaded (/usr/lib/systemd/system/httpd.service; disabled)
          Active: inactive (dead) since Tue, 19 Feb 2013 11:18:57 +0530; 2s ago
         Process: 4563 ExecStart=/usr/sbin/httpd $OPTIONS -k start (code=exited, status=0/SUCCESS)
          CGroup: name=systemd:/system/httpd.service

我尝试用谷歌搜索这个错误,所有链接都指向清除信号量。我不认为这是问题,因为我尝试清除信号量,但没有成功。

在这里我们看到了一个问题的证据:

tail: inotify resources exhausted

默认情况下,Linux 只为 inotify 分配 8192 个监视点,这个值低得离谱。当它用完时,错误也是No space left on device,如果您没有明确寻找这个问题,这可能会令人困惑。

使用适当的 sysctl 提高该值:

fs.inotify.max_user_watches = 262144

(将此添加到/etc/sysctl.conf然后运行sysctl -p。)
