You have 3 sites, each of which is an LVS. If any site completely
fails, you would like another site to take over. If you want these
3 sites to just be failovers for the other sites, then you need a
HA layer above the 3 LVSs. If you want to regard each site as a single
machine which is either on-line or off-line, and you want to load
balance these 3 machines, then you need another layer of LVS to balance
the 3 sites. Alternately you could have 8 realservers balanced by a
director (and its backup) at one site.

yes
