Description

Description

Reinstalling Couchbase and then attempting to start it results in ns_server crashing.

Steps to reproduce

Spawn a completely new vagrant virtual machine running 7.0.0-4390 on Centos7.

Stop and remove Couchbase.

systemctl stop couchbase-server

yum -y remove couchbase-server

Download build 7.0.0-4390

wget http://172.23.126.166/builds/latestbuilds/couchbase-server/cheshire-cat/4390/couchbase-server-enterprise-7.0.0-4390-centos7.x86_64.rpm

Reinstall and start Couchbase

yum -y install couchbase-server-enterprise-7.0.0-4390-centos7.x86_64.rpm

systemctl start couchbase-server

What happens:

The installation succeeds, but ns_server crashes. The output of 'systemctl status couchbase-server -l' shows the following:

systemctl status couchbase-server -l

Furthermore, I could not make http requests to 'localhost:8091' using curl or wget.

The ns_server.error log file reports additional errors (see appendix).

A reason for why this may happen:

With help from Daniel Owen, I was able to narrow down what might be the cause.

Post uninstallation, the 'chronicle' folder is left behind:

[root@node1-cheshire-cat-testing-centos7 ~]# tree /opt/couchbase/var/lib/couchbase/config/chronicle/

/opt/couchbase/var/lib/couchbase/config/chronicle/

├── logs

│   └── 0.log

└── snapshots

Deleting this folder after the uninstall and before the reinstall prevents the crash after reinstallation.

 rm -rf /opt/couchbase/var/lib/couchbase/config/chronicle/

What I expected to happen:

I expected ns_server to start successfully after reinstallation.
