Thanks again for your kind answer mr. Patricio,
I wish to ask your professional help online via anydesk or zoom whatever, willing to pay for your work.
please contact me if you're willing at my work email:

in case you wont do then here some questions and doubts....

I dunno how to do these procedures please kindly give me example:
- quote yours:"you can always do a fresh-reset on MySQL server which does clean every entry in DD."

quote:"you can always restart each MySQL server and let it resync its DD with NDB" I've done this already 3 times. i totally shut down ndb and turn off all VM's,
then turn on in order:
1) mngm node with mysqld node 1
2) data node 1 which stuck for 13 mins. i was waching tail -f logs
so i decided to start data node2 and then both start to do them duty
until both online and connected to mgnm node
3) mysql node 2 which has ver. 8.0.34 while all others 8.0.33

I've decided to try update all nodes to 8.0.36 next week in this order:
1) mgng and mysql node1 with v.8.0.33
2) mysql node2 with v.8.0.34
3) data node1 with v.8.0.33
4) data node2 with v.8.0.33
i have doubt abt this, for mysql nodes it's enough apt upgrade i guess, but for data not working so i have to download manually DEB files.
My question is, i'll just install with dpkg those new versions or i have to delete first the old one?
if i delete old one i'll lose all data ?
Thanks for your answers.
