Collecting the metasave image of a file system
You can collect a metasave image of a file system for troubleshooting file system issues. Metadata is a data structure that contains attributes about the data within a file system, but does not contain the actual data itself. You can use metadata images for tracking file system trends, such as the file size, age, and type of information in the file system.
Note:
When using the support metasave command to create a consistent metasave image, if the file system is not offline on all the cluster nodes, a warning appears which has to be confirmed before you proceed. You can bring the file system offline using the storage fs offline command before collecting the metasave image. Metasave image collection is a time consuming operation. The total time that is required depends on the amount of metadata information present in the file system. You can run other Access Appliance operations from a separate terminal while running the metasave operation.
To collect the metasave image of a file system
- To use the Support> metasave command, enter the following:
Support> metasave [fsname] [output_location]
fsname
Specifies the name of the file system for which you want to collect a metasave image of the file system.
output_location
Specifies the directory location of the metasave image.
For a regular file system, a single metasave image is stored at the directory location specified by output_location.
For example, to collect the metasave image of file system testfs, and store it under
/tmp/meta_out_dir, enter the following:Support> metasave testfs /tmp/meta_out_dir Collecting metasave image of file system testfs. This may take some time... SUCCESS: Metasave image of testfs collected successfully. Image is stored at /tmp/meta_out_dir.
