Troubleshooting Guide


Open-ESS does not behave very differently from Open-E DSSv7, other than setup of the main storage array.

Here are some notes to help you handle issues that might arrive.

DSSv7 Logs:  Open-E logs are accessible from the Open-E web management interface.  Select "Status" "Hardware" and scroll down to "Logs".  You can download all logs as a zip archive, or you can view individual logs.

Viewing Logs:  The logs are text files in Unix text format.  This means that line endings are line-feeds only.  Windows uses carriage-return / line-feed characters instead.  This means that some applications will not view logs well.  For example, windows notepad will show logs as one long line.

To view logs in Windows, you can use Windows Wordpad, or you can download an app like GEDIT.

ESS Logs:  The logs that are most relevant to ESS start with ESS in their name.  Specifically:

ess-admin.log - Log of command captures from the ESS adminitration text application.
ess-mount-0.log - Log of the last array mount operation.
