3.0.1->4.0 Upgrade questions/notes

Couchbase Server
1

Just attempted an upgrade on a 3-node cluster. Community edition, centos 6.6.

The plan was to do an online rolling swap. Remove a node, rebalance, shut down the node’s services, remove the rpm, install new rpm, re-add node to cluster. Repeat.

Some questions and notes on the upgrade.

  1. Installing the new rpm produces the error/warning:

    1:couchbase-server-commun########################################### [100%]
tar: /opt/apps/couchbase/lib/python/pysqlite2.tar: Cannot open: No such file or directory
tar: Error is not recoverable: exiting now
Starting couchbase-server-community

I checked and no such tar file exists in that directory nor in the rpm itself
My rpm command is:
rpm -ivh --relocate /opt/couchbase=/opt/apps/couchbase couchbase-server-community-4.0.0-centos6.x86_64.rpm

  2. Re-adding a node (new version) to the cluster (old version) produces the error:

    Attention - Node attempting to join an older cluster. Some of the selected services are not available.

I assume this is simply because the services (data/index/query) are separated out now. Choosing just the “data” service allowed me to continue. This meant after getting all nodes on the new version, they all had just the “data” service.
To get them to have all services, do i have to go back to each node and do a remove/rebalance/re-add and then i’ll be able to pick all the services on setup?

  1. to use N1QL, should i have the Query service running on ALL of my nodes? And is there no way of using the Query service without running the Index service? In the setup it auto-checks the Index service if I check the Query service.

Thanks,

-Tony

I have the same issue! I am upgrading by doing a rolling swap and I cannot add my new nodes to the couchbase 3.x cluster. How do I get the new nodes running all three couchbase services but still able to do a rolling swap?
