inotify报错upper limit on inotify

在对一个大磁盘进行inotify监听时，爆出如下错误：

Failed to watch /mnt/;

upper limit on inotify watches reached!

Please increase the amount of inotify watches allowed per user via `/proc/sys/fs/inotify/max_user_watches’.

cat一下这个文件，默认值是8192，echo 8192000 > /proc/sys/fs/inotify/max_user_watches即可~
