hello,

i have installed on my own way a mongo on a ec2 amazon : i have followed this tutorial but after i am questionning my self :

1 ) they say in this page to use ext4 file system :
sudo mkfs.ext4 /dev/xvdf
sudo mkfs.ext4 /dev/xvdg
sudo mkfs.ext4 /dev/xvdh
but i've read in others place that xfs will be better for mongo ? It's a specific reason ( amazon linux betters with ext4 ) ?

2) the version of mongo is not the last one :
echo "[mongodb-org-3.2]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/amazon/2013.03/mongodb-org/3.2/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-3.2.asc" |
sudo tee -a /etc/yum.repos.d/mongodb-org-3.2.repo
