我在我的电脑上使用arch linux（64位机器）安装了mongo。 在开始之前，我已经将mongo数据库文件移动到具有大量（11 Gb）空间的新位置。但如果我运行mongod，它会失败，因为设备上没有空间。如果我以root身份运行它，则可以运行。我的潜在问题在哪里？我是mongo的新手。
mongo version
$ mongod --version
db version v3.0.7
git version: nogitversion
mongo conf
$ cat /etc/mongodb.conf
# See http://www.mongodb.org/display/DOCS/File+Based+Configuration for format details
# Run mongod --help to see a list of options
bind_ip = 127.0.0.1
quiet = true
#dbpath = /var/lib/mongodb
dbpath = /home/data/mongodb
logpath = /var/log/mongodb/mongod.log
logappend = true

检查可用空间
$ sudo -u mongodb df -h /home/data/mongodb/
