Inside Solaris™ 9

Tuning File Systems

A situation might arise in which you want to change some of the parameters that were set when you originally created the file system. Perhaps you want to change the minfree value to free some additional disk space on a large disk drive. Using the tunefs command, you can modify the following file system parameters:

• maxcontig

• rotdelay

• maxbpg

• minfree

• optimization

See Table 14.6 for a description of these options.

Caution

tunefs can destroy a file system in seconds. Always back up the entire file system before using tunefs.

The syntax for tunefs is as follows:

tunefs [ -a <maxcontig> ] [ -d <rotdelay> ] [ -e <maxbpg> ] [ -m <minfree> ]\ 
[ -o [ <value> ] special/filesystem 

The tunefs command is described in Table 14.6.
