Yeah, validate is set for ALL pools, and we still sometimes see savesets
show up in the savegroup comletion wherein maybe all but one of the
savesets will have a 'V', but the other day I saw a notification wherein
many of the savesets were missing the 'V' but others had it. Nothing out
of the ordinary occured that I can tell, and there were no failures or
errors. Everything completed. So, I'm not sure what to make of the
missing 'V's. I guess we just ignore it?
