Hi,
As you might have noticed, we have been facing some backend storage
issues that affect several services, most noticeable repo.eclipse.org
and several Jenkins instances. In order to fix this, we need
to migrate all Jenkins Home dirs to a different storage device.
For most of the Jenkins instances that are rather small, this migration
can be done quite quickly in half an hour or less.
For a handful of Jenkins instances, the migration will take longer,
depending on the used disk space and the number of files.
During the migration, the Jenkins instances will be offline. After the
migration, everything should work as before.
During the next few weeks, smaller instances will be migrated, when it's
their turn. If required, we will announce maintenance windows
for larger instances.
In order to speed up the migration, we would like to encourage all
projects to clean up their Jenkins instances:
* Get rid of old build jobs (especially if they are several years old)
* Limit the number of builds to keep with artifacts (remember that
Jenkins is not a file server)
* Please make sure that Multibranch pipeline jobs have the following
settings enabled:
* Scan Repository Triggers -> Periodically if not otherwise run: 2 days
* Orphaned Item Strategy -> Discard old items -> Max # of old items
to keep: 5

Your support in this effort is much appreciated.
Regards,
Fred
