По умолчанию все данные хранятся в разделе /var.

Допустим, мы подключили отдельный диск к /storage.

1. Работаем под root пользователем

   sudo su

2. Останавливаем ресиверы и БД

   systemctl stop qoestor_fullflow_0.service
   systemctl stop qoestor_clickstream_0.service
   sudo /etc/init.d/clickhouse-server stop

3. Создаем каталоги в разделе /storage

   mkdir /storage/qoestor
   mkdir /storage/qoestor/clickhouse
   mkdir /storage/qoestor/clickhouse-hot
   mkdir /storage/qoestor/clickhouse-cold
   mkdir /storage/qoestor/dump

4. Копируем данные на новый диск

   cp -r /var/lib/clickhouse/* /storage/qoestor/clickhouse
   cp -r /var/lib/clickhouse-hot/* /storage/qoestor/clickhouse-hot
   cp -r /var/lib/clickhouse-cold/* /storage/qoestor/clickhouse-cold
   cp -r /var/qoestor/backend/dump/* /storage/qoestor/dump

5. Меняем владельца папки /storage/qoestor/clickhouse

   chown -R clickhouse:clickhouse /storage/qoestor/clickhouse
   chown -R clickhouse:clickhouse /storage/qoestor/clickhouse-hot
   chown -R clickhouse:clickhouse /storage/qoestor/clickhouse-cold

6. Удаляем старые каталоги

   rm -rf /var/lib/clickhouse
   rm -rf /var/lib/clickhouse-hot
   rm -rf /var/lib/clickhouse-cold
   rm -rf /var/qoestor/backend/dump

7. Создаем симлинки

   ln -s /storage/qoestor/clickhouse /var/lib/clickhouse
   ln -s /storage/qoestor/clickhouse-hot /var/lib/clickhouse-hot
   ln -s /storage/qoestor/clickhouse-cold /var/lib/clickhouse-cold
   ln -s /storage/qoestor/dump /var/qoestor/backend/dump

8. Проверяем линки

   readlink -f /var/lib/clickhouse
   readlink -f /var/lib/clickhouse-hot
   readlink -f /var/lib/clickhouse-cold
   readlink -f /var/qoestor/backend/dump

9. Запускаем БД

   sudo /etc/init.d/clickhouse-server restart

10. Запускаем ресиверы

    sudo sh /var/qoestor/backend/qoestor-config.sh
