Changing zFS attributes on a mounted zFS compatibility mode file system
- AGGRFULL
- AGGRGROW
- CONVERTTOV5
- FSFULL
- RWSHARE
- NORWSHARE
These attributes typically remain with that file system until it is explicitly unmounted. When all systems are at z/OS V2R3, some of these attributes can be changed dynamically with the zfsadm chaggr command. Otherwise, they can only be changed when the file system is unmounted and remounted, as indicated in the rest of this section. For more information about zfsadm chaggr, see zfsadm chaggr.
- The file system is NORWSHARE and z/OS® UNIX ownership moves to another system with a different zFS default.
- The file system is remounted
samemode
and the z/OS UNIX owning system has a different default. - The file system is remounted from read-only to read/write and the z/OS UNIX owning system has a different default.
- The file system is NOAUTOMOVE and the system is coming up with a different default.
The RWSHARE and NORWSHARE attributes of a compatibility mode file system may also be changed if they were assigned from a zFS default of the system on which they were mounted.
- The file system is remounted from read-only to read/write and the z/OS UNIX owning system has a NORWSHARE default.
- The file system is NOAUTOMOVE and the system is coming up with a NORWSHARE default.
- The file system has z/OS UNIX ownership moved to another system that has specified RWSHARE as the default.
- The file system is remounted from read-only to read/write and the z/OS UNIX owning system has an RWSHARE default.
- The file system is NOAUTOMOVE and the system is coming up with an RWSHARE default.

You can change a zFS attribute on a mounted file system. To do so, take an appropriate action, as previously described for the attribute that you want to change. For example, to change the NORWSHARE attribute of a compatibility mode file system to RWSHARE, you can move the z/OS UNIX ownership of that file system to a different system that specifies RWSHARE as the zFS default.
