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

/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.
