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. 2021-05-21 07:11:03.527 1062 INFO trove.guestagent.datastore.manager [-] Resizing the filesystem at /var/lib/mysql, online: True 2021-05-21 07:11:03.528 1062 DEBUG trove.guestagent.volume [-] Checking if /dev/sdb exists. _check_device_exists /home/ubuntu/trove/trove/guestagent/volume.py:217 2021-05-21 07:11:03.528 1062 DEBUG oslo_concurrency.processutils [-] Running cmd (subprocess): sudo blockdev --getsize64 /dev/sdb execute /opt/guest-agent-venv/lib/python3.6/site-packages/oslo_concurrency/processutils.py:384 2021-05-21 07:11:03.545 1062 DEBUG oslo_concurrency.processutils [-] CMD "sudo blockdev --getsize64 /dev/sdb" returned: 0 in 0.016s execute /opt/guest-agent-venv/lib/python3.6/site-packages/oslo_concurrency/processutils.py:423 2021-05-21 07:11:03.546 1062 DEBUG oslo_concurrency.processutils [-] Running cmd (subprocess): sudo resize2fs /dev/sdb execute /opt/guest-agent-venv/lib/python3.6/site-packages/oslo_concurrency/processutils.py:384 2021-05-21 07:11:03.577 1062 DEBUG oslo_concurrency.processutils [-] CMD "sudo resize2fs /dev/sdb" returned: 0 in 0.031s execute /opt/guest-agent-venv/lib/python3.6/site-packages/oslo_concurrency/processutils.py:423 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. - Ammad On Thu, May 20, 2021 at 4:39 PM Lingxian Kong <anlin.kong@gmail.com> wrote:
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 ?
