Installing Globus

Login Into Globus CLI

  • Once you have installed the Globus CLI or are using the Dockerimage, you will need to login. When using the dockerimage you will need to include the --no-local-server option and follow the directions it gives.

globus login

globus login --no-local-server

Globus CLI options

  • Below is a list of some of the options available when using the Globus CLI.

Globus endpoint Command

  • The endpoint command has many options, but the one that is most useful is the search option as you can use this option to search for the ID of an endpoint via name.

globus endpoint search "WashU RIS"

  • An endpoint search using WashU as the search terms with bring up any endpoints that are related to that term. Multiple endpoints will show up, but the one you want to use is RIS Storage1.

ID                                   | Owner                   | Display Name
------------------------------------ | ----------------------- | -----------------------------------------
7e92c283-7513-4d54-acdf-516f027bfeb2 | wustl@globusid.org      | RIS Storage1

  • The ID is the information that will be utilized in the other options. Please note that the correct RIS endpoint is the one named RIS Storage1. The others are being phased out.

Globus ls Command

  • Once you have the ID of the endpoint you wish to use, you can use globus ls just like you use ls in linux/unix to display the files and directories in a directory.

  • The Wash U RIS storage1 dtn1/dtn2 endpoints are the storage1 endpoints and will display what is in your storage1 directory. The following command demonstrates how to do that.

globus ls 7e92c283-7513-4d54-acdf-516f027bfeb2:/storage1/fs1/wustlkey/Active/

Globus transfer Command

  • Once you have determined the endpoints that you wish to use to transfer data, you can utilize the transfer command. You can transfer between the WashU endpoints to move data that way.

  • There are three ways you can transfer data.

    • Transfer individual files.

    • Transfer a directory, using the recursive -r option.

    • Transfer files in bulk using the --batch option.

  • Transfering an invdividual file.

globus transfer 7e92c283-7513-4d54-acdf-516f027bfeb2:/path/to/source/location/my_file.txt 7e92c283-7513-4d54-acdf-516f027bfeb2:/path/to/destination/location/my_file.txt

  • Transfering a directory.

globus transfer -r 7e92c283-7513-4d54-acdf-516f027bfeb2:/path/to/source/location/my_directory 7e92c283-7513-4d54-acdf-516f027bfeb2:/path/to/destination/location/my_directory
  • Transfering using the --batch option

    • You need to provide the directories that you are transferring between like with the transfer of a directory.

    • You need a space separated text file with the location of the files in the source endpoint followed by the location in the destination endpoint. Each file must have it’s own line.

    Sample1.txt Group1/Sample1.txt
Sample2.txt Group1/Sample2.txt
Sample3.txt Group1/Sample3.txt
Sample4.txt Group2/Sample4.txt
Sample5.txt Group2/Sample5.txt

    • With the batch method, you can sort files from the source into separate directories in the destination or pull files from separate directories in the source into one directory in the destination.

    Group1/Sample1.txt Sample1.txt
Group1/Sample2.txt Sample2.txt
Group2/Sample3.txt Sample3.txt
Group2/Sample4.txt Sample4.txt
Group2/Sample5.txt Sample5.txt

    • You can provide the file of the files you wish to transfer to the command with the < option.

    globus transfer --batch 7e92c283-7513-4d54-acdf-516f027bfeb2:/path/to/source/location/my_directory 7e92c283-7513-4d54-acdf-516f027bfeb2:/path/to/destination/location/my_directory < files_to_transfer.txt

Viewing Transfer and Task Information

Globus retains task information for 90 days. This is not controlled by RIS.

Commands in this section support the -F/--format json option for easier programmatic processing.

Transfer Status

Given a transfer task ID, information about the status of the task can be retrieved with task show:

[user@host cwd]$ globus task show 543e219c-01c1-11eb-81a3-0e2f230cc907
Label:                   None

Transferred Filenames

The task info command can also produce a list of successfully transferred files when the -t/--successful-transfers option is used:

[user@host cwd]$ globus task show -t 543e219c-01c1-11eb-81a3-0e2f230cc907
Source Path         | Destination Path
------------------- | --------------------------------------------------------
/~/godata/file1.txt | /storage1/fs1/corcoran.william.p/Active/godata/file1.txt
/~/godata/file2.txt | /storage1/fs1/corcoran.william.p/Active/godata/file2.txt
/~/godata/file3.txt | /storage1/fs1/corcoran.william.p/Active/godata/file3.txt

  • This information is only available to the task owner (user), not RIS

  • This information is only available through the CLI and SDK, not the web UI

Event and Failure Logs

Timing and activity information (including errors) can be obtained with task event-list:

[user@host cwd]$ globus task event-list 543e219c-01c1-11eb-81a3-0e2f230cc907
