I’m in a bit of new territory in terms os working with the root file system for
USS.
I have a small sysplex for development and recently I was looking to install
some additional software that I’d like to place under a mount point off `/`. I
could find something existing but it is more intuitive to add a new mount point
in root and mount a ZFS over it.
The systems are in a SYSPLEX but all USS filesystems are independent so there
is no sharing across the systems at this point.
The plex is able to IPL one of three versions of z/OS (2.3, 2.4 or 2.5) at a
time.
Each version has its own root FS. My diabolical plan was to run 2.5 and then
mount the 2.3 and 2.4 file systems using RDWR mode, add the entry, unmount, do
the next one and then re-ipl. on 2.4 install the new software anchored off the
new mount point.
When trying to mount one of the older ROOT FS using this MOUNT command
MOUNT FILESYSTEM('OMVS.ROOT.MT24R1') -
MOUNTPOINT('/var/omvsroot') -
TYPE(ZFS) -
MODE(RDWR)
I am getting these messages when attempting to mount as RDWR … READ mounts fine.

open aggregate OMVS.ROOT.MT24R1.
As with many things VSAM there is a lot of data and so little information.
DIAGNOSE on the VVDS runs clean and indicates no errors.
I’m continuing to diagnose the issue but I presume this should be fairly
straight forward so any guidance is welcome.
