- Open 4 shell sessions:
- One to the Lustre MDS
- tail -f /var/log/messages
- Threeto the Data mover "copy01" in my case
- tail -f /var/log/messages
- Working shell for copy tool launch
- Testing shell
- One to the Lustre MDS
- In the working shell we will be starting the data mover with the debug flag.
- Be sure to monitor the logs on both servers and the debug output from the lhsmd command for any errors.
| Tip |
|---|
The "lhsmd" command will not terminate in this instance, expect some very verbose output on the screen and then for it to suddenly stop, by this point check using "lfs df -h" to see if the frontend filesystem has been mounted. If you wish to terminate this you will need to issue a "Ctrl + C" |
