Basic checks

• Check if your nodes are all reachable by IP address as well as by hostname
• Check if your network has the right throughput
• Check if your disks are all working and do not report errors
• Check your Chunkservers for:
  • Broken Disks
  • Slow Disks
  • permissions on your directories (the user which is running the chunkserver must be the owner of the directories)
  • network performance to other chunkserver
  • network performance to master server
  • network performance to clients
• Check your license files for the correct name and location
• Check your log files for errors. SaunaFS is very talkative and reports a lot.
