FS under test  : hammer2 2-node local cluster (dd-copied MASTER pair, shared pfs_clid)
Devices        : /dev/vn0 /dev/vn1 (1GB file-backed, vnconfig -c -S -T)
Mount          : mount -t hammer2 /dev/vn0@CLUS /mnt/c2 ; second node joins via
                 mount_hammer2 /dev/vn1@CLUS (EBUSY "PFS already mounted!", cluster stays 2-wide)
Stress         : stress.sh (60s file churn + iroot metadata churn) vs tight sync loop
