We have in a test environment a 2 nodes cluster (not ideal, but should work) base one community edition (4.5.0-2601). Let’s call those two nodes A and B.
In that cluster we have multiple buckets. Browsing using the UI, I can see all buckets on both nodes. And for each bucket, the document count matches.
But we started noticing problems when a service connecting to node A [edit: I thought it was node B, but it is actually node A that is addressed by that service] says it cannot find a bucket:
[{“msg”:“Keyspace not found keyspace sdk_couchbase - cause: No bucket named sdk_couchbase”,“code”:12003}]
Trying to find out what was happening, I played the select * from system:keyspaces; either in the query tab of the UI or via the query workbench and I have strange results:
- on node A, in the query workbench, I see all the buckets. On node B, I only see one (the only one that has no password and an index AFAIK);
- one node A, in the UI query tab, I only see one bucket (same one as on node B in query workbench) and on node B, I see them all.
Looking for doc about it, I saw that keyspaces == buckets and I am expecting to see all buckets coming up when running select * from system:keyspaces; on both node A and B and in both instances of query browser.
Am I missing something?
PS: after noticing the initial problem reported by the service, I removed node B, added it back and rebalanced. But nothing changed. And query workbench has default configuration, connection to CB on localhost:8091
