MSDP storage full conditions
Operating system tools such as the UNIX df command do not report deduplication disk usage accurately. The operating system commands may report that the storage is full when it is not. NetBackup tools let you monitor storage capacity and usage more accurately.
See About MSDP storage capacity and usage reporting.
See About MSDP container files.
See Viewing storage usage within MSDP container files.
Examining the disk log reports for threshold warnings can give you an idea of when a storage full condition may occur.
How NetBackup performs maintenance can affect when storage is freed up for use.
See About MSDP queue processing.
See About the MSDP data removal process.
Although not advised, you can reclaim free space manually.
