I think vdsm domains do have their own meta-data except the lvm or
posix file system meta data.
the export domain is an NFS domain and the size is not
listed in its
metadata. much like posix which is based on file type storage, if we
extend the size in the storage server itself the domain size will be
updated with no issues or changed to the metadata.
you are correct regarding iscsi domain types which would have a problem
with extending a lun in the storage side.
extend for iscsi is done via the ovirt by editing the domain and adding
more luns since extend of the used lv on the storage side will cause
issues in the metadata.

If the export domain come back to life, I think the domain meta data
should be invalidated after the extend.
since its not iscsi type domain the extend
done on the server side to
extend the domain should not be a problem
