Fernando's SMART status aggregator

SSH into multiple servers, run smartctl and aggregate results into a CSV.

Usage

1. Install smartctl on every host:

   ansible all -m shell -a 'sudo apt-get -y install smartmontools'

2. Update smartctl's drive database:

   ansible all -m shell -a 'sudo update-smart-drivedb'

3. Run SMART "long" test on every disk of every host:

   ansible all -m shell -a 'smartctl --scan | cut -d "#" -f 1 | xargs -I {} smartctl -a {} -t long'

   Wait a few hours for them to complete.

4. Add all hosts to be tested to ~/.ssh/config, e.g.:

   Host ifill
       HostName ifill
       AddressFamily inet
       User ansbl
       ProxyJump tarbell
       IdentityFile ~/.ssh/mediacloud-ansbl-20200812
   
   # <...>
   

5. Run smart_aggregate.py against all hosts:

   ./smart_aggregate.py --host \
       tarbell \
       berstein \
       posey \
       bly \
       lowery \
       steinam \
       woodward \
       ramos \

       wells \
       sinclair \
       bradley \
       ifill \
