This is because your servers have some files from an old installation. Remove them. On all nodes, run these command below logged in as root:

/usr/sbin/rmsecattr -c /usr/lib/methods/defacfsctl
/usr/sbin/rmsecattr -c /usr/lib/methods/udefacfsctl
/usr/sbin/rmsecattr -c /usr/lib/methods/cfgacfsctl
/usr/sbin/rmsecattr -c /usr/lib/methods/ucfgacfsctl
/usr/sbin/rmsecattr -c /usr/lib/methods/defadvmctl
/usr/sbin/rmsecattr -c /usr/lib/methods/udefadvmctl
/usr/sbin/rmsecattr -c /usr/lib/methods/cfgadvmctl
/usr/sbin/rmsecattr -c /usr/lib/methods/ucfgadvmctl
/usr/sbin/rmsecattr -c /usr/lib/methods/cfgadvmvol

rm -rf /sbin/helpers/acfs
rm /usr/sbin/acfsutil* /usr/sbin/advmutil*
rm /sbin/acfsutil* /sbin/advmutil*

After that, run root.sh again
