Chapter 6 Managing the File System

Managing File System Operations

File System Block Size: This value defines the granularity of the file system's allocation size. The default setting is 16,384. The block size must be specified in powers of 2.

Inode Cache Size: This value defines the number of inodes that can be cached in the SNFS server. The default setting for the cache size is 16, and the minimum is 8.

Maximum Log Size: This value defines the maximum number of bytes (size) to which a SNFS Server log file can grow. When the log file reaches the specified size, it is rolled and a new log is started. In this situation, the two log files could use twice the maximum log size space specified in this field. The range is from 1 to 256 megabytes.

Maximum Number of Logs: This value determines the number of rolled logs kept. Choices range from 1 to 10.

Journal Size: This value controls the size of the file system journal. The range is 1 to 256 megabytes.

Thread Pool Size: This value defines the number of client pool threads to be activated and used by the SNFS server. This setting affects system performance. There should be at least two threads per client. Increasing the number of threads will improve file system response time in operations that affect allocation and metadata functions. The range is from 16 to 1024 threads.

Migrating File System: Enable this option (check the box) if the data on the file system should be migrated to tertiary storage. Migration cannot be disabled once it is enabled.

Global Super User: Enable this option (check the box) to allow a user with super-user privileges to assert these privileges on the file system.

Note: If the Global Super User option is enabled, super users have global access rights on the file system. This selection is the same as the maproot=0 directive in the Network File System (NFS).

If the Global Super User option is not enabled, super users can modify only files they can access, like any other users.
