磁盘空间已用尽，需要删除文件。
1.查看磁盘使用情况
[root@jr-yfb-ng_tm-10-94 usr]# df -h
2.查找使用目录下大于某个阈值的文件大小
[root@jr-yfb-ng_tm-10-94 usr]# find . -size +200M
具体如下：
[root@jr-yfb-ng_tm-10-94 usr]#
date: write error: No space left on device
[root@jr-yfb-ng_tm-10-94 usr]#
date: write error: No space left on device
[root@jr-yfb-ng_tm-10-94 usr]# df -h
