I am trying to use the magento-cloud cli and getting the following error when i try to use the magento-cloud db:size command.

vagrant@ubuntu-bionic:~$ magento-cloud db:size
Enter a number to choose a project:
  [0] Project SMC(dbname)
 > 0

Enter a number to choose an environment:
Default: master
  [0] Integration (integration)

  [1] database-ro (dbname_ro)
  [2] database-slave (dbslavename)

Checking database service mysql...

  The command failed with the exit code: 1

  '\''username'\'' --password='\''pass'\'' --host='\'''\'' --port=3306 --no-auto-rehash --raw --skip-column-names' 

Any ideas why it is happening? Is there a possibility that it is due to a read-only user?

Did you try this method?

magento-cloud ssh -eproduction -pPROJECTID

then the usual command

df -h | grep -E 'mysql|mnt|Filesystem'

Try to login to MySQL using CLI, can you do that?


Once you log in to mySQL, try doing cli

magento-cloud mount:size
