Description
The copy directory is too small.

Probable Causes
There is not enough free space in the file system containing the copy directory to accommodate the dump.

Recommended Actions
Increase the size of that file system.

Detail Data
File system name
/var/adm/ras
Current free space in kb
71104
Current estimated dump size in kb

devdb01:/># cd /var/adm
devdb01:/var/adm># du -sg *
1.91 wtmp
...

发现wtmp占用了近2G的空间。/var/adm/wtmp文件以二进制的形式保存所有用户登录的信息，随着登录次数的增多
如果不及时清理，这个文件会变的很大。

清理方法：
devdb01:/var/adm>cat /dev/null > wtmp

devdb01:/var/adm># du -sg wtmp
0.00 wtmp
