Troubleshooting
Upload or Retrieval taking a long time¶
Uploading or retrieving data can sometimes take longer than expected. tmux is a terminal multiplexer, a multiplexer enables the creation and control of multiple terminals from a single screen. It also allows the detachment of a screen to run in the background with the ability to re-attach and start where you left off.
An example of starting and using a tmux session:
# create new tmux session called 'data_transfer'
tmux new -s freezer_transfer
# cd to directory containing files to upload
cd /nesi/nobackup/<project_id>/myproject
# put data 'your_folder' into Freezer bucket
s3cmd put --recursive --verbose your_folder s3://<freezer_bucket>/your_directory/your_folder
tmux session by:
ctrl + b, then d
Detatching the tmux session, allows you to close your primary terminal and logoff while the upload continues.
To reattach to the session:
tmux attach -t freezer_transfer
The tmux session(s) will remain until you terminate it, or the node is rebooted.
