Not to worry, this can be resolved. First, shutdown Appian gracefully if possible. Since there is no more space left on the disk, you will need make space before attempting to restart again; please see forum.appian.com/.../Data_Maintenance.html

Once you have created enough free space, then you can start Appian again. If you are unable to start Appian via start-suite, let us know and we will guide you through next steps.

P.S When using the cleanup script, make sure that you only remove old, obsolete kdbs: please do not delete all, and at least keep the last 3 (or more, incase you need to recover data)
