Hello....

I'm try to build instance m1.tiny [RAM 2GB - VCPUs 1 - Disk 40GB] successfully. After that, this instance resize to m1.medium [RAM 8GB - VCPUs 4 - DIsk 80GB] successfully. I check disk in dashboard instance specs RAM 8GB, VCPUs 4, Disk 80GB, but in dashboard volumes still 40GB. Im try to remote instance with ssh and check:

free -m => 8GB
cat /proc/cpuinfo => 4 vcpu
df -h ==> /dev/vda1 still 40GB.

Can help me to fix it? I'm using Centos7 with Openstack Rocky.

The disk got larger (use lsblk to confirm), but OpenStack doesn't interfere with the instance's content. This includes the filesystem size: You are responsible for sizing the root filesystem.

Is vda a volume or ephemeral storage? I believe that the flavor only affects ephemeral storage, not volume-based storage.

This is not ephemeral storage. This instance create new volume in cinder, but not increase after resize instance.

That’s your problem. Volumes are not affected by flavors.

yes, so I just resize volume manually, correct?
