expdp的par文件如下：
$cat expdp_bip20190324.par
userid=" / as sysdba"
directory=DUMP
dumpfile=expdp_bip20190324.dmp
logfile=expdp_bip20190324.log
cluster=n
exclude=statistics
content=metadata_only
COMPRESSION=all
schemas=(

)
上网查了下说是有限制的，查了下ulimit
$ulimit -a
time(seconds) unlimited
file(blocks) 209715100
data(kbytes) unlimited
stack(kbytes) 4194304
memory(kbytes) unlimited
coredump(blocks) 2097151
nofiles(descriptors) unlimited
threads(per process) unlimited
processes(per user) unlimited
file(blocks)应该有100G了，应该够用的。而且我dd if=/mydirectory of=mytestfile bs=4096 count=1048576，是可以生成一个4G的文件的。
所以现在不知道怎么解决这个问题。
专家解答
将file size设置成unlimited
