create_fastlinks

[IT_2007]

Does create_fastlinks kernel parameter setting to "1" support for VxFS filesystems or only for HFS?

Did anybody tested this setting to 1 for VxFS?

thanks.

Hi:

VxFS filesystems do this behind the scenes automatically. The parameter has no meaning for them.

Only HFS. From "SAM's Help on Configurable Kernel Parameters":

When create_fastlinks is non-zero, it causes the system to create HFS symbolic links in a manner that reduces the number of disk block accesses by one for each symbolic link in a pathname lookup.

It only applies to HFS filesystems. Vxfs filesystems and hfs filesystems are fundamentally very different and the fastlink concept of the hfs (or UFS) filesystem really has no counterpart.

It would be helpful to know what kind of problem with symbolic links that you are trying to solve.

somewhere I read it does support VxFS but not sure. Anyway thanks for quick replies.
