Since:
- I have no volumes using this volume type
- I defined in in the [DEFAULT] section of cinder.conf the attribute
"default_volume_type" to a value different than "__DEFAULT___"
I assume that I can safely delete the __DEFAULT__ volume type
Is this correct?
Yes, as long as there are no volumes using it and there is a valid volume type defined with ``default_volume_type`` config in cinder.conf, you can safely delete it. NOTE: ``default_volume_type`` has a default value of ``__DEFAULT__`` to not allow users to further create untyped volumes, if you are deleting this, make sure there is always a valid volume type defined with ``default_volume_type`` in cinder.conf
Thanks, Massimo

Hi Rajat,
I retyped all remaining volumes of type "__DEFAULT__" but I still can't delete that type, apparently it's marked as default somewhere, but I can't find anything in the database referring to __DEFAULT__ except the cinder.volume_types table. I tried to delete it:
---snip--- controller02:~ # openstack volume type list +--------------------------------------+-------------+-----------+ | ID | Name | Is Public | +--------------------------------------+-------------+-----------+ | f27162b0-c3c4-4929-8a95-89b83875885f | __DEFAULT__ | True | [...] +--------------------------------------+-------------+-----------+
controller02:~ # openstack volume type delete f27162b0-c3c4-4929-8a95-89b83875885f Failed to delete volume type with name or ID 'f27162b0-c3c4-4929-8a95-89b83875885f': Target volume type is default and cannot be deleted. (HTTP 400) (Request-ID: req-859c6546-a368-4f6f-ab02-80000c4404c1) ---snip---
But according to cinder I have a different default-type:
---snip--- controller02:~ # cinder type-default +--------------------------------------+------+-------------+-----------+ | ID | Name | Description | Is_Public | +--------------------------------------+------+-------------+-----------+ | 5f7f9e7f-a5b4-4061-b228-022d42139467 | hdd | | True | +--------------------------------------+------+-------------+-----------+ ---snip---
How do I get rid of that type now?
Regards, Eugen

This is probably because your cinder package version isn't updated to 15.4.0 (Train) Your deployment should contain this patch[1] to make it work To verify, you can run ``cinder-manage --version`` command
But according to cinder I have a different default-type:

Hi,
that is very helpful, thank you!
Indeed, our version is:
controller02:~ # cinder-manage --version 15.2.1
I will update in the near future and see if this is resolved.
Thanks again! Eugen

Just to confirm, updating cinder to said version was the solution to delete the __DEFAULT__ volume-type.
Thanks, Rajat!

Hi,
I haven't been following the discussion, but default type is defined in cinder.conf in Train, and loaded on service start, so you should check your cinder.conf file and if you changed it, or it has changed since your last restart, you need to restart your Cinder services.
Cheers, Gorka.
