Thanks.,that helps...
So..what happens if I have in existing path on a smaller drive and I
attach a new volume and switch? In essence looking for best practice on
how ot handle this.
Is it better to do a rolling upgrade where I start new machines fresh with
1T then remove the smaller nodes 1 by one? So...I have three nodes with 20
gigs each. Increase to 6 nodes. Then one one by remove the old nod and
now back to three with 1T each. It does seem that a rolling upgrade
involves much less risk.
Thanks
