# DF-2585 — build a local 2-node hammer2 cluster (two identical MASTER copies
# share the same pfs_clid, so mounting both devices as one cluster gives
# iroot->cluster.nchains == 2 => xops run at clindex 1, which is the only
# way hammer2_xop_inode_flush's volume-dedup loop (flush.c:1377-1384) ever
# executes).
