Hi Ammad,

Do you mind reporting the issue to trove storyboard https://storyboard.openstack.org/#!/project/openstack/trove with the detailed steps to reproduce? It'd be great if you could provide the openstack service versions you are using as well. Thanks.

Thanks Lingxian, it worked fine.

I have resize the volume of mysql datastore from 17GB to 18GB. In guest agent logs it said that command has executed successfully.

But the /var/lib/mysql still shows 17GB. I have manually executed resize2fs on /dev/sdb. After manual execution, /var/lib/mysql has updated to 18GB. Not sure if I am missing something.

Modify trove service config file:

[DEFAULT]

max_accepted_volume_size = <any value bigger than 10, maybe 15?>

10 is the default value if the config option is not specified.

Hi,

I am using wallaby / trove on ubuntu 20.04. I am trying to extend volume of database instance. Its having trouble that instance cannot exceed volume size of 10GB.

My flavor has 2vcpus 4GB RAM and 10GB disk. I created a database instance with 5GB database size and mysql datastore. The deployment has created 10GB root and 5GB /var/lib/mysql. I have tried to extend volume to 11GB, it failed with error that "Volume 'size' cannot exceed maximum of 10 GB, 11 cannot be accepted". 

I want to keep root disk size to 10GB and only want to extend /var/lib/mysql keeping the same flavor. Is it possible or should I need to upgrade flavor as well ?
