Hi,
I have a upgraded a secondary in our replica set. Then the secondary node is waiting startup2 mode. I know this normal according to below documantation.
But i wanted to ask two question.
Our database size is almost 3.5TB and one of our secondary node deployed another location and bandwith is not enough for the 3.5TB initial sync.
So, is the secondary fetching all data from primary? (i mean initial sync) or checking/fixing data?
I thought, it will fix old version data to new version data in database. Because our data folder in my secondary node still 3.5TB. This is not like initial sync.
if initial sync mandatory, is it possible to work different minor version of mongo in the same replicaset. Because i started upgrade process in my secondary server. If initial sync is not mandatory, i will upgrade all replica set member.
Thanks.
