====== Setting up storage on a separate disk ======
{{indexmenu_n>1}}

By default, all data is stored in the /var section.

For example you have a separate drive connected to /storage.

  - Work from the root user <code>sudo su</code>
  - Stop the recievers and DB <code>fastor-stop
fastor-db-stop</code>
  - Create directories in the /storage section<code>mkdir /storage/qoestor
mkdir /storage/qoestor/clickhouse
mkdir /storage/qoestor/clickhouse-hot
mkdir /storage/qoestor/clickhouse-cold
mkdir /storage/qoestor/dump
</code>
  - Copy tha data on the new drive <code>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
</code>
  - Change the folder owner /storage/qoestor/clickhouse <code>chown -R clickhouse:clickhouse /storage/qoestor/clickhouse
chown -R clickhouse:clickhouse /storage/qoestor/clickhouse-hot
chown -R clickhouse:clickhouse /storage/qoestor/clickhouse-cold
</code>
  - Delete the old directories <code>rm -rf /var/lib/clickhouse
rm -rf /var/lib/clickhouse-hot
rm -rf /var/lib/clickhouse-cold
rm -rf /var/qoestor/backend/dump
</code>
  - Create simlinks <code>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
</code>
  - Check the links <code>readlink -f /var/lib/clickhouse
readlink -f /var/lib/clickhouse-hot
readlink -f /var/lib/clickhouse-cold
readlink -f /var/qoestor/backend/dump
</code>
  - Start the DB <code>fastor-db-restart</code>
  - Start the recievers <code>fastor-restart</code>
