Version-Release number of selected component (if applicable):
OSP18
How reproducible:
100%
Steps to reproduce:
1. Log into osp18 controller pod and create a flavor as below, can see the disk size is 50G
sh-5.1$ openstack flavor list ...... | e85c1fbf-9939-4a93-8baf-1a96ef6c9a61 | medium | 8192 | 50 | 0 | 4 | True |
2. Create an instance from a volume using falvor medium and disk size of volume is 40G
sh-5.1$ openstack server create --flavor medium --volume rhel9.5-volume --nic net-id=08fce52a-995a-4d2b-8624-8f2d646388a0 --availability-zone nova rhel9.5-instance

3. Check the disk of instance after finishing launching, found the disk size of instance is 40G
[root@rhel9-5-instance ~]# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS sr0 11:0 1 474K 0 rom vda 252:0 0 40G 0 disk ├─vda1 252:1 0 1G 0 part /boot └─vda2 252:2 0 9G 0 part ├─rhel-root 253:0 0 8G 0 lvm / └─rhel-swap 253:1 0 1G 0 lvm [SWAP]
Additional info:
1. The disk size set in falvor takes effect when creating instance from image on osp18
2. I remember that the disk size set in falvor can take effect when creating instance from volume on osp17
