# Based on hvm image @ 2014-07-25 10:45

# Manually set up mongo and friends (overkill to automate this)
# Got the mongohq data from
#      mongodump --host hydra.mongohq.com:10097 -u daniel -p toiletpapirunderforhuden --db myproject -o ./

# Formatted attached storage:
mkfs.xfs -L mongo -s size=4096 /dev/xvdb

# Adde to fstab and mounted:
echo 'LABEL=mongo   /mnt   xfs   defaults,noatime   0 1' >> /etc/fstab
mount /mnt

# Set up mongo repo:
apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10
echo 'deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen' > /etc/apt/sources.list.d/mongodb.list
apt-get update

# Installed mongo:
apt-get install mongodb

# Moved data to /mnt
service mongodb stop
rsync -avx /var/lib/mongodb /mnt/
rm -rf /var/lib/mongodb
ln -s /mnt/mongodb /var/lib/mongodb
service mongodb start

# Changed my mind, and went with btrfs for compression and built-in snapshotting.
# Upgraded to mainline kernel 3.15.7-031507.201407281235 generic.
# Attached a new 15GB General Purpose SSD volume, and:
apt-get install btrfs-tools
mkfs.btrfs -L mongodb /dev/xvdf
mkdir /mongodb
echo 'LABEL=mongodb   /mongodb   btrfs   defaults,noatime,discard,compress-force=lzo   0 1' >> /etc/fstab
mount /mongodb
btrfs subvolume create /mongodb/current

# Killed the parser and the mongodb service, then
rsync -avx /mnt/mongodb/ /mongodb/current/
rm /var/lib/mongodb
ln -s /mongodb/current /var/lib/mongodb

# Cleaned prev mongo /mnt from fstab, destroyed storage.
