I tried to upgrade 2.0.8.0 to 2.0.11.0 but yb-ctl create fails like this: ``` jk@tiira:~/bin2/yugabyte-2.0.11.0/bin$ ./yb-ctl create --rf 1 Creating cluster. Waiting for cluster to be ready.

@jk-1 Can you try and see if it works ?: 0. `pkill yb-tserver` && `pkill yb-master` (or `./bin/yb-ctl stop`) 1. download the new binary into a new directory 2. run `./bin/post_install.sh` in the new version 3. new-binary-directory `./bin/yb-ctl start` ---

@jk-1– It’s possible that there are processes left over from previous install. Let’s check: `/home/jk/yugabyte-data/node-1/disk-1/master.out & /home/jk/yugabyte-data/node-1/disk-1/master.err ` files, and similarly, these files: `/home/jk/yugabyte-data/node-1/disk-1/tserver.out /home/jk/yugabyte-data/node-1/disk-1/tserver.err` to see why those processes didn’t start. ---

I did yb-ctl destroy post\_install.sh yb-ctl create --rf 1 yb-ctl start Ports 7000 & 9000 are up I can log into ysqlsh and status is ``` jk@tiira:~/bin2/yugabyte-2.0.11.0/bin$ yb-ctl status ---------------------------------------------------------------------------------------------------- | Node Count: 1 | Replication Factor: 1 | ---------------------------------------------------------------------------------------------------- | JDBC : jdbc:postgresql://127.0.0.1:5433/postgres | | YSQL Shell : ysqlsh | | YCQL Shell : cqlsh | | YEDIS Shell : redis-cli | | Web UI : http://127.0.0.1:7000/ | | Cluster Data : /home/jk/yugabyte-data | ---------------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------------- | Node 1: yb-tserver (pid 8390), yb-master (pid 8387) | ---------------------------------------------------------------------------------------------------- | JDBC : jdbc:postgresql://127.0.0.1:5433/postgres | | YSQL Shell : ysqlsh | | YCQL Shell : cqlsh | | YEDIS Shell : redis-cli | | data-dir[0] : /home/jk/yugabyte-data/node-1/disk-1/yb-data | | yb-tserver Logs : /home/jk/yugabyte-data/node-1/disk-1/yb-data/tserver/logs | | yb-master Logs : /home/jk/yugabyte-data/node-1/disk-1/yb-data/master/logs | ---------------------------------------------------------------------------------------------------- ``` So it seems to work. Thank you for your support! I tried without post\_install first because this guide does not mention it: [Upgrade a deployment | YugabyteDB Docs](https://docs.yugabyte.com/latest/manage/upgrade-deployment/) So do I need to run post\_install always after upgrade? ---

Yes. We’re fixing the missing docs: [[DOCS] add install-new-version to upgrade-steps by ddorian · Pull Request #3508 · yugabyte/yugabyte-db · GitHub](https://github.com/yugabyte/yugabyte-db/pull/3508) ---

post\_install.sh is a one time thing that you need to do after downloading a new release bundle. [You don’t need to do it for every stop/start or destroy/start cycle.]
