I'm testing the sharing of a zFS file system between sysplex'd
z/OS 2.1 and z/OS 1.13 systems. The file system is to be mounted
at a mountpoint that contains a symlink containing $VERSION in its
definition. That is, the mountpoint is '/usr/local' but '/usr' is a
symlink defined as '$VERSION/usr'.
On the z/OS 2.1 system, this mountpoint resolves to
'/Z21/usr/local'. On the z/OS 1.13 system, it resolves to
'/Z1D/usr/local'.
When the z/OS 2.1 system is IPL'd first, the file system
successfully mounts at '/Z21/usr/local'. When the z/OS
1.13 system is IPL'd second, the mount is refused with message:
BPXF237I FILE SYSTEM USER.TOOLS WAS ALREADY MOUNTED ON PATHNAME
/Z21/usr/local.
How does one make the USERS.TOOLS file system available to the
z/OS 1.13 at /usr/local (which resolves to /Z1D/usr/local)?
Configuration:
BPXPRMxx - SYSPLEX(YES)
IOEPRMxx - sysplex=filesys and sysplex_filesys_sharemode=NORWSHARE
Mount command:
MOUNT FILESYSTEM('USER.TOOLS')
TYPE(ZFS)
MODE(read) UNMOUNT
MOUNTPOINT('/usr/local')
