- My man pages say otherwise:
-
- This program should work on mounted and active file systems.
- Because the super-block is not kept in the buffer cache, the
- program will only take effect if it is run on dismounted
- file systems; if run on the root file system, the system
- must be rebooted.
- ^^^^^^^^
-
- And when I run tunefs (using SunOS 4.1.2), I get:
-
- walker2.hu(1)# tunefs -m 15 /
- minimum percentage of free space changes from 10% to 15%
-
- Did you reboot afterwards?
