date: write error: No space left on device

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
