seedAndSpread() calls `volume.grow -dataNode X` without pinning the rack.
The master's grow picks the rack by weighted-random when -rack is unset,
and only one of the three racks holds the requested data node, so an
unpinned grow lands on the wrong rack two times out of three. The
VolumeGrow RPC swallows the "No matching data node" failure for
non-cache collections, so those grows count as success without creating
a volume. The per-server cap (maxGrowsPerServer=4) is then exhausted by
silent no-ops before the volumes ever spread, and seedAndSpread times
out with "volumes never spread across >=2 disks on all 3 nodes".
Pin -dataCenter dc1 and -rack rack{i} alongside -dataNode so every grow
reaches the target node. This removes the timing-sensitive assumption
that made TestECVacuumDuplicateShardClaimAcrossDisks flaky.
