We are facing an issue in production - Rebalancing takes long time and finally stuck.
We use Couchbase community edition 3.0.1. This is a 6 node cluster with 5 Couchbase buckets and 1 memcached bucket and No replication.
Total : 120 GB
In USe: ~1.5GB
Disk: ~1.5 GB
When data is present rebalance takes long time. Waited for more than 2 Hrs and the operation was not progressing at all. From the log it is found that rebalancing is a “swap rebalance”.
Once the data is flushed and rebalanced, the operation completed within 15 min. We faced a hardware failure in production last day and finally we had to flush all the data to complete the rebalance.
Appreciate any help to solve this rebalancing issue.
