Description Peng Sun 2026-01-23 09:58:16 UTC 
Current OS detecting way:

# ctdb/config/functions
if [ -x /sbin/startproc ]; then
    CTDB_INIT_STYLE="suse"
elif [ -x /sbin/start-stop-daemon ]; then
    CTDB_INIT_STYLE="debian"
else
    CTDB_INIT_STYLE="redhat"
fi

If package dpkg is installed on CentOS node, the node will been detected as Debian incorrectly and nmbd service is required but not exists.
Comment 1 Martin Schwenke 2026-01-25 03:43:14 UTC 
This behaviour was changed in Samba v4.20.  OS type detection now uses /etc/os-release.

Samba 4.12.7 is no longer supported.  Please only report bugs against supported versions.
