Author: Mark McBride <[email protected]>
Source: https://github.com/markmcb/storage-scripts
Description: This script runs locally and to all servers listed and runs all of the
storage scripts, collects their outputs, and emails them.
Dependencies: This script assumes the following binaries are available, but you could
replace them with equivalents:
1. Keychain - https://www.funtoo.org/Keychain - allows you to cache ssh passwords
2. msmtp - https://marlam.de/msmtp/ - an SMTP client to send email
3. storage-scripts - the three other scripts available at the github link above
IMPORTANT: This script does require root priviledges.
!!!!!!!!!! CONFIGURE IT FIRST !!!!!!!!!!
You need to do three things before this script will work:
1. Change any variables in ALL CAPS to meet your needs.
2. Look for the comment "Servers" below. Add/remove blocks and the associated ALL CAPS
variables to meet your needs.
3. Look for the variable DID_NOT_READ_THE_INSTRUCTIONS and change it to anything
but 1. (Or just delete it and the if statement below it.)
