Kill the leftover orphan processes in the login nodes

...

If users are performing a regular check for orphan processes, then they will need to traverse along all access the login and data-mover nodes individually and check for orphan processes on each of them. Currently there are 4 login nodes available to users going from -01 to -04.

titleOnly connect to specific login nodes to perform killing of orphan processes

...

At any given time, the set of login and data-mover nodes that are accessible may be determined by running the following commands from a terminal session on whichever login or data-mover node you have logged into

, which provides access assigning the connection to different login nodes in a round robin fashion. This allows for better load balancing of resources among all users. Furthermore, the use of the generic name provides a more reliable access as it can provide service to users on active login nodes while some specific login nodes may have been taken down by Pawsey staff for technical reasons.

Once the user has logged into the desired login node, execute the ps command together with "filtering" with the grep command acting repeatedly on the output to narrow it down to only those processes owned by the user and related to "vscode":

titleTerminal 2. Finding unexpected/orphan VS Code processes

Here, having logged into setonix-06, we obtain the list of IP addresses for the currently accessible login nodes, and then convert those IP addresses back into the individual nodes names.
in this instance, we can see that we should also check for leftover processe on setonix-01 and setonix-05

The following example shows the commands to obtain the list of names for the currently available data-mover nodes, having logged into setonix-dm01

Note
titleOnly connect to specific login nodes to perform killing of orphan processes

Only use direct connection to specific login nodes when performing cleaning of orphan processes. For the rest of your connections users should be using the generic name setonix.pawsey.org.au, which provides access assigning the connection to different login nodes in a round robin fashion. This allows for better load balancing of resources among all users. Furthermore, the use of the generic name provides a more reliable access as it can provide service to users on active login nodes while some specific login nodes may have been taken down by Pawsey staff for technical reasons.

As the user has already disconnected from any VS Code active session, and the "cleaning" connection is being performed outside VS Code, then users can visually confirm that those processes are indeed the orphan processes of interest. Now they can proceed to kill them by extending the command to extract a list of the process IDs and passing that list to the kill command:

Now that users are taking some time to clean the login nodes from their orphan processes then, as recommended above, it is a good idea to go through all the active login nodes and perform a check on all of them (and kill the orphan processes that are identified).

Preventing Visual Studio Code to consume your quota in the $HOME file system

Home is often used by a variety of programs use store configuration files and directories along with some cached information. These directories can contain many files and use up quite a bit of storage. An example is vscode, which stores quite a bit of data within the .vscode-server  directory located in $HOME . This directory can contain upwards of 1000 files and use on the order of 100 MB. This will impact your quota on home. We recommend moving such directories to /software/projects/<project>/<username>  and generating a symbolic link in $HOME.

Preventing Visual Studio Code to consume your quota in the $HOME file system

Excerpt

Home is often used by a variety of programs use store configuration files and directories along with some cached information. These directories can contain many files and use up quite a bit of storage. An example is vscode, which stores quite a bit of data within the .vscode-server  directory located in $HOME . This directory can contain upwards of 1000 files and use on the order of 100 MB. This will impact your quota on home. We recommend moving such directories to a "fakeHome" directory in: /software/projects/<project>/<username>/fakeHome. Then generate a symbolic link in $HOME that points to the corresponding directory:

Column


Code Block
languagebash
themeDJango
titleTerminal X. Setting .vscode-server directory out of the HOME directory
$ mkdir -p $MYSOFTWARE/fakeHome
$ cp -r $HOME/.vscode-server $MYSOFTWARE/fakeHome   # if .vscode_server dir initially exists in $HOME
$ rm -r $HOME/.vscode-server                        # if .vscode_server dir initially exists in $HOME
$ mkdir -p $MYSOFTWARE/fakeHome/.vscode-server      # if .vscode_server did not initially existed in $HOME
$ ln -s $MYSOFTWARE/fakeHome/.vscode-server $HOME/.vscode-server       # generate a symbolic link


Note that we are using cp + rm and not mv to transfer the .vscode-server directory to another filesystem in order to get the right ownership of files in the new filesystem and remove their original ownership that is consuming the $HOME quota, otherwise the quota of the transferred files would still be assigned to $HOME quota.

Further explanation of quotas can be found in Pawsey Filesystems and their Use.
