have not been reset since server startup.
Name Space Statistics:

is a single tape storage segment that contains more than one file.
• Files in Tape Aggregates. The number of files in the tape aggregates managed by this Core
Server.
• Bytes in Tape Aggregates. The number of bytes stored in the tape aggregates managed by this
Core Server.
• Active Disk Bytes. This is the sum of the bytes in the storage segments assigned to files, including
slack space. Slack space is the disk space assigned to disk storage segments that is not occupied
with file data. The sum of the lengths of files on disk will be less than the Active Disk Bytes
because of the presence of slack space.
• Free Disk Bytes. This is the sum of the bytes not assigned to files. More precisely, it is the sum of
the disk volume bytes not assigned to disk storage segments.
• Active Tape Bytes. This is the sum of the bytes assigned to files on tapes. It does not include
deleted file space that has not been reclaimed.
