2 解决方法
2.1 方法1
设置 DM_INSTALL_TMPDIR 变量，指定到别的路径下，注意磁盘空间要大于 2G。
export DM_INSTALL_TMPDIR=/dm/tmp
2.2 方法2
直接修改修改/tmp 大小：mount -t tmpfs -o size=3G none /tmp
[dave@www.cndba.cn software]# df -lh
Filesystem Size Used Avail Use% Mounted on
devtmpfs 456M 0 456M 0% /dev

再次运行安装正常：
[dave@www.cndba.cn mnt]$ ./DMInstall.bin -i
Please select the installer's language (E/e:English C/c:Chinese) [E/e]:
Extract install files..........

pending signals (-i) 3644
max locked memory (kbytes, -l) 64
max memory size (kbytes, -m) unlimited

The max number of open files is too little, suggest to set 65536 or more to number of open files.
