Minfree option for vxfs filesystems

[Ken Pannell]

With HFS filesystems there is a command "tunefs" that has the option for setting the percentage of space that is not available to normal users. Is there a similar option that can be used for vxfs filesystems?

If you do a man mkfs_vxfs, you will not find an equivalent option to minfree for mkfs_hfs. While it is true that fstyp -v /dev/vgxx/lvoln does report separate values for f_bfree (total free blocks) and f_bavail (blocks available for non-superusers) and these values are different, I'm all but certain there is no way to do this for a vxfs filesystem. In the past, I've looked for low-level calls to do do this but have not been sucessful.

In any event, the wiser approach is to have a daemon which checks for filesystem usage and alerts you before there is a problem.

Thanks for the input. Your answer is what I thought I would get.
