Prune C3Jenkins adoptium mirror workspace of old versions to save space

[andrew-m-leonard]

The adoptium mirrors and the older non-Adoptium old mirrors, keep a workspace for each version, we may have workspaces on C3Jenkins for old versions we no longer mirror (jdk-15,16,18,....) ?

To save space these old workspaces can be deleted:

Also, there are some of the older non-Adoptium mirror job output under
/home/jenkins/.jenkins/workspace/git-mirrors :

The stuff under git-mirrors directly is pretty small - about 5Mb each. I'll clear them up too though along with the others you mentioned.

Hmm they all seem to have been updated fairly recently (Most on September 15th) including the ones that aren't in the adoptium directory. Are they definitely not being run? If I delete them and the jobs are still active they'll just be regenerated.

They were still running, and failing..! I disabled them when I discovered them...

I've left 21 in place just now in case something odd happens before 21.0.1 but the others have now been cleared - good spot on this one!
Probably another thing to add to the "Stuff to do on a new version" checklist.

Pruned workspace/build-scripts-pr-tester/build-test/@ (i.e. when multiple jobs run in parallel) which cleared another 30Gb or so.
