Post migration ELK issue


(harish) #1

We have completed the migration of 3 nodes elasticsearch (2.2 to 5.5) , before migration we took the snapshot of all the indices which around 1TB and 3756 shards .
After the migration when we monitoring on the cerebro the totals shards are not matching and data is growing twice .

Before

After upgrade

can some one help us understanding the behavior .

Exactly double! Any chance the second graph is counting replicas as well whereas the previous one was simply counting only primaries?

You have way too many shards by the way.
Use _shrink to reduce that.
