Hi SNOs,
The next software upgrade includes a change that will by default send piece deletions to the trash rather than immediately removing them from disk. This is a temporary precaution to avoid failing audits for pieces that were deleted between satellite database backups if we have to restore from a previous backup. Each node still has the option to turn this configuration off, but we highly recommend you keep it on. It is very unlikely that we will have to restore from a satellite database backup (we have never had to restore from backup thus far), but in the event we do, this will be the only way for you to avoid audit failures and potential disqualification.
