Reclaim disk space by removing orphaned archive files

You can save disk space by removing orphaned archive filesClosed Versioned files that users have submitted to a depot. and their associated metadata records. An orphaned file that exists in the server depot's archive storage but that lacks a reference. Archives with a reference count of 0 are rare, but might be created by incomplete p4 submit or p4 shelve commands or system crashes.

To reclaim that disk space:

  1. Run p4 storage -l because it spawns a background process that looks for files in the specified //depotdirectory and its subdirectories that match the naming convention for the server's archive file format. Each file that is found along with its revision is checked for a matching entry in the db.storage table. If no such entry is found, a new record is created that describes the file and revision combination with a reference count of 0.
  2. Run p4 storage -d to delete those 0 references records along with the associated archive file.
