Re: Data nodes took too long to start after updating config.ini on Management node

Hi,
Hard to say without more data.
A node can restart in anything from a few seconds to hours dependent
on how much data to restore and how many LDM threads are there to
perform the restore of the data.

If you use 7.4 there is a fair amount of logging in the node log such
that you can see more details about where it is spending its time.

There is even an ndbinfo table that shows how NDB data nodes moves
through the 20 start phases and how much time it has taken in each
one of them.
