Hello people,

In a ndb cluster with two DB nodes (2 replicas, 1 node group), I have noticed
that if I try to start only one of the two DB nodes, its start up process is
progressing very slowly. It stays a lot of time at 'phase #1' and then it stucks in 'phase #2'. I waited
for about ten minutes but it never passed phase 2. If I start the two DB nodes together they are coming up pretty fast. The same
happens when one of the two DB nodes is already started, and I start the other. What causes the DB node to progress so slow when it runs alone? What if both my
DB nodes crash and (for any reason) I am unable to start both of them (so they
start in a reasonable amount of time)? Do I have to change my configuration to
one-db-node in such case? Looking forward for your suggestions. Regards, Yannis Tsakiris
