Scripts for automation of I/O workload and Ceph failure injection. Uses COSbench to apply I/O workload; pbench for monitoring and SSH scripts (dropOSD.bash) to inject failures.

For a writeup of how the ceph cluster was installed see: https://github.com/ekaynar/Benchmarks/blob/master/ceph-ansible/README.md

FILE INVENTORY:

• vars.shinc - global variables
• writeXMLs.sh
• prepCluster.sh
• runtest.sh - main driver script which executes COSbench and injects failures
• XMLtemplates (directory)
  • TMPL_deletewrite.xml
  • TMPL_prepCluster.xml
  • TMPL_hybrid.xml
• Utils (directory)
  • dropOSD.bash - script which is run on OSDhostname (drops an OSD device)
  • functions.shinc - collection of functions
  • pollceph.sh - script run on MONhostname (polls ceph status)

USAGE:

• Edit 'vars.shinc' for your environment (hostnames; runtime; obj sizes ...)
• run 'writeXMLs.sh' <-- create COSbench workload files
• run 'prepCluster.sh' <-- create pools and fill the cluster
• run 'runtest.sh' <-- run the test and record results
