Skyhook Development on CloudLab

1. Spin up CloudLab instance (try image skyhookceph-ubuntu14-1osds)
2. Install packages:

sudo apt-get update ;
sudo apt-get install tmux ;
sudo apt-get install vim ;

3. Change hostnames on all nodes to avoid networking confusion. On client0:

sudo hostname client0 ;
HOSTNAME=client0 ;

On osd0:

sudo hostname osd0 ;
HOSTNAME=osd0 ;

4. Edit /etc/hosts on each node to clean up addresses sudo vi /etc/hosts
   e.g.

127.0.0.1       localhost
10.10.1.2       client0
10.10.1.1       osd0

5. On client0, copy these files from the shared directory.

cp /proj/skyhook-PG0/projscripts/format-sda4.sh . ;
cp /proj/skyhook-PG0/projscripts/cluster_setup_copy_ssh_keys.sh  . ;

6. Copy your PRIVATE Cloudlab ssh key from your login machine (e.g. your laptop) to a new ~/.ssh/id_rsa on each node of your Cloudlab instance and change permissions to 0600.

chmod 0600 .ssh/id_rsa ;

7. On client0, configure the cluster ssh.

sh cluster_setup_copy_ssh_keys.sh ;

8. On client0 ONLY, make sure sda4 is the 500GB SSD (check with lsblk) and run format-sda4.sh. If sda4 is not the 500GB SSD, replace the string 'sda4' in the format-sda4.sh script with the appropriate identifier.

sh format-sda4.sh ; # pass in username e.g. 'sh format-sda4.sh kat ;'

9. Clone the Skyhook repo into /mnt/sda4.

cd /mnt/sda4 ;
git clone https://github.com/uccross/skyhook-ceph.git

10. Install and build Skyhook.

sudo ./install-deps.sh ;
./do_cmake.sh ;
cd build/ ;
tmux new -s mybuild
make -j34
detach from the build session CONTROL-B D

11. Spin up the virtual cluster.

../src/stop.sh ;
make vstart ;
../src/stop.sh;
../src/vstart.sh -d -n -x;
bin/ceph -s ;
bin/rados mkpool tpchflatbuf ;
bin/ceph osd lspools ;
wget https://users.soe.ucsc.edu/~jlefevre/skyhookdb/testdata/skyhook.test2objs.flatbufv2.lineitem.0 ;
wget https://users.soe.ucsc.edu/~jlefevre/skyhookdb/testdata/skyhook.test2objs.flatbufv2.lineitem.1 ;
yes | PATH=$PATH:bin ../src/progly/rados-store-glob.sh tpchflatbuf  skyhook.test2objs.flatbufv2.lineitem.* ;
bin/rados df  # should see tpchflatbuf pool with the 2 above objects ;
bin/run-query --num-objs 2 --pool tpchflatbuf --wthreads 1 --qdepth 10 --query flatbuf --select "*" ;
bin/ceph -s ;

12. Check if it worked.
