Lustre is GPL2, which makes its inclusion into a closed-source OpenVMS 
configuration comparatively unlikely.

ZFS, if VSI decides to license that from Oracle, might work.  ZFS and 
various other choices would likely require some changes for application 
compatibility and for clustering — the caches would have to be 
coordinated across cluster members — and getting a wholly new file 
system to operate in the XQP environment and with the existing DCL 
commands and system services would involve some work.

It's certainly conceivable that they'd extend fields in ODS-5.

VSI might also decide to implement disk partitioning.

The addressing change effects code throughout the VMS kernel and in VSI 
and third-party application code.  Code that uses a longword block 
count or a longword block address, such as device drivers, 
disk-reporting tools and likely including SNMP, and potentially even in 
foreign file systems which would want or need to address these larger 
volumes.

What VSI might decide here, we shall learn.
