StorNext File System Tuning

The Metadata Controller System

Settings greater than 64K are not recommended because performance will be adversely impacted due to inefficient metadata I/O operations. Values less than 16K are not recommended in most scenarios because startup and failover time may be adversely impacted. Setting FsBlockSize to higher values is important for multiterabyte file systems for optimal startup and failover time.

Note: This is particularly true for slow CPU clock speed metadata servers such as Sparc. However, values greater than 16K can severely consume metadata space in cases where the file-to- directory ratio is low (e.g. less than 100 to 1).

The best rule of thumb is to use 16K unless other requirements such as directory ratio dictate otherwise.

This setting is not adjustable after initial file system creation, so it is very important to give it careful consideration during initial configuration.

The optimal settings are in the range between 16M and 64M. Avoid

values greater than 64M due to potentially severe impacts on startup and

failover times. Values at the higher end of the 16M-64M range may

improve performance of metadata operations in some cases, although at

the cost of slower startup and failover time. A good rule of thumb is to

use 16M unless another requirement dictates differently. This setting is

adjustable using the cvupdatefs utility. For more information, see the

cvupdatefs man page.

performance. You can use this utility to determine whether files are

 

fragmented, and if so, fix them. If your files are prone to fragmentation

 

you should also use the FSM config file tuning options to minimize

 

fragmentation. These global configuration settings are InodeExpandMin,

 

InodeExpandInc, and InodeExpandMax. (For more information, see the
