I'm guessing that you mean a QFS file system built using SVM volumes? You want to grow a filesystem on these volumes?
- How to grow the volumes depends on how they're built; this would require seeing either the command that built them or metastat -c for them. You have to expand each column of the volume equally if it is a striped volume type.
- To extend the file system, you need to stop using it, edit the MCF properly to add the next extents, and then extend the file system. See the samgrowfs man page for details.
I realize this isn't a definitive answer, but it's not possible to give you one without seeing the metastat output and the QFS MCF file.
