Hi all:

               I encouted a problem when I tried to create vm from a big-size image(4G) on a AIO node, and get error messages like:

‘’’VolumeNotCreated: Volume 4c186b68-542e-453c-ab77-0e5272337289 did not finish being created even after we waited 642 seconds or 209 attempts. And its status is error.\n","stream":"stdout","time":"2019-09-05T10:31:51.947340783Z"}’’’

Refere to answer from openstack community like :

https://ask.openstack.org/en/question/115832/volume-did-not-finish-being-created-even-after-we-waited-some-seconds/

Tuning  parameters “block_device_allocate_retries”, “block_device_allocate_retries_interval” in nova.conf of compute node can resolve the problem.

               But after checking current nova.conf in nova-compute pods, found nova.conf have already been set like that

               [DEFAULT]

‘’’

               block_device_allocate_retries = 2400

block_device_allocate_retries_interval = 3

‘’’

Seem retries(2400)*interval(3)=7800 sec didn’t take effect on my env.

Did anyone encounter that problem before ?  Glad for any suggestion.

Best Regards
