Upgrade instructions

Prepare for upgrading SENTIENT (CentOS, Ubuntu)

Stop SENTIENT Check if SENTIENT and database services are running Initially SENTIENT, check status to ensure it is stopped and then databases.

1

sudo systemctl stop sentient

1

sudo systemctl status sentient

Backup Database

Make a backup of the database before upgrading.

PostgreSQL

Check PostgreSQL status. It is unnecessary to stop PostgreSQL for the backup.

1

sudo systemctl status postgresql

Make sure you have enough space to place a backup of the database
Check database size

1

sudo -u postgres psql -c "SELECT pg_size_pretty( pg_database_size('sentient') );"

Check free space

1

df -h /

If there is enough free space - make a backup.

1

sudo -Hiu postgres pg_dump sentient > sentient.sql.bak

Check backup file being created.

Cassandra

Check Cassandra status. It is necessary to stop Cassandra for the backup.

1

sudo systemctl status cassandra

Flush all memtables from the node to SSTables on disk.

1

nodetool drain

Stop Cassandra.

1

sudo systemctl stop cassandra

And you have to check the status again to ensure they are surely stopped.

1

sudo systemctl status cassandra

Make sure you have enough space to place a backup of the database
Check database size.

1

du -h /var/lib/cassandra/ | tail -1

Check free space.

1

df -h /

Make a backup of Cassandra database.

1
2

mkdir backup
sudo tar -cvf backup/cassandra.tar /var/lib/cassandra

Check archive being created

Start Database

Cassandra

1

sudo systemctl start cassandra

PostgreSQL Do nothing, postgresql is already running.

If you use Redis for caching, you need to flush all stored keys before starting the SENTIENT.

Connect to your Redis instance (or container/pod, depending on your setup) and run the command:

redis-cli flushall

Please note that this command is applicable only if you use Redis exclusively for SENTIENT. If other applications use Redis, you need to locate the SENTIENT database and flush only that. The default database index is 0, configurable with REDIS_DB SENTIENT environment value.
