Viewing storage usage within MSDP container files
The NetBackup crcontrol command reports on storage usage within containers.
To view storage usage within MSDP container files
- Use the crcontrol command and the --dsstat option on the deduplication storage server. (For help with the command options, use the --help option.)
The following is an example of the command usage:
UNIX and Linux: /usr/openv/pdde/pdcr/bin/crcontrol --dsstat
Windows:
install_path\Veritas\pdde\Crcontrol.exe --dsstat
The following is an example of the output:
************ Data Store statistics ************ Data storage Raw Size Used Avail Use% 1.0T 988.9G 666.0G 322.9G 68% Number of containers : 2981 Average container size : 219740494 bytes (209.56MB) Space allocated for containers : 655046415189 bytes (610.06GB) Reserved space : 45360705536 bytes (42.25GB) Reserved space percentage : 4.1%For systems that host a 96-TB Media Server Deduplication Pool, you can use the following crcontrol command to show information about each partition:
/usr/openv/pdde/pdcr/bin/crcontrol --dsstat 3
From the command output, you can determine the following:
Raw
The raw size of the storage.
Size
The size of the storage that NetBackup can use: the Raw size of the storage minus the file system Reserved space.
If the file system has a concept of root reserved space (such as EXT3 or VxFS), that space cannot be used for storage. The crcontrol command does not include reserved space in the available space. Unlike the crcontrol command, some operating system tools report root reserved space as usable space.
Used
The amount of deduplicated data that is stored on the file system. NetBackup obtains the file system used space from the operating system.
Avail
The Size minus the Used space.
Use%
The Used space divided by the Size.
