Filesystem full /var/go

[Kalpesh Malviya]

Hi Team,

We have installed go-agent on the linux box.

After successfully installation we changed the working dir by editing the file
`/usr/share/go-agent/wrapper-config/wrapper-properties.conf` to add the following line  : `wrapper.working.dir=/data/go-agent` 

Now after few months we have recieved a mail from the linux team that there is space full on path /var/go.  I'm not sure whether the files present under the dir /var/go is been used anymore as the current working dir is /data/go-agent. 

Can you please check and confirm whether the contents of dir /var/go can be deleted

I am attaching the contents of /var/go below here.

Hi  Kalpesh,

From the output provided it looks like /var/go is some user's home directory.

I recommend checking to see if the user "go" is still using this directory as its home directory. If it is, I recommend further analysis on the contents of the directory to determine what can be safely deleted.

Hope this helps,

Jason

Hi Jason,

Unfortunately we did some investigate and couldn't figure out which files we need to get rid of. 
There were lot of npm files, Cypress one's etc..,

Hi Kalpesh,

Unless I am missing something, this does not seem to be a GoCD question at this point.

There is a server that has the role of a GoCD Agent. There is a directory on that server outside of the GoCD Agent directory that is full. The full directory appears to be the home directory of the user that runs the GoCD Agent but the only way to know that for sure is to review the server configuration. GoCD itself will not put anything outside of the working directory unless explicitly or implicitly directed to do so by the specific process being implemented. (For example, the process as implemented could require downloading npm packages to the GoCD account's home directory.)

If this server's only role is as a static GoCD Agent, I recommend decommissioning it and building a replacement. From GoCD's perspective, everything on the Agent should be disposable once a Pipeline run is complete so you lose nothing of value by rebuilding.

Alternately, take a backup of the entire /var/go directory and then delete whatever you like. In theory this is fine but I can't comfortably recommend it because I don't know nearly enough about your environment to be able to say whether or not deleting any given thing from the file system is safe.

Good luck,

Jason
