I have no such reason... :)
But as you noticed rightly this situation will occur during upgrade process...

Then my next question is:

What is the algorithm of upgrading nodes in cluster without loosing its availability?
1. Stop mgmt-node
2. Upgrade mgmt-node
3. Start mgmt-node
4. Repeat steps 1-3 for every mgtm-node in cluster
5. Stop SQL-node
6. Upgrade SQL-node
7. Start SQL-node
8. Repeat steps 5-7 for every SQL-node in cluster
9. Stop NDB-node
10. Upgrade NDB-node
11. Start NDB-node
12. Repeat steps 9-11 for every NDB-node in cluster

Or may be there are some tricks during this process?

Thanks for answer!
