I launched a VM instance with Flavor-1 | 1GB RAM | 2 VCPU | 25.0GB Disk, i checked the file system it was fine. After some time i did resize instance to Flavor-2 | 2GB RAM | 2 VCPU | 10.0GB Disk. After confiem resize instance i checd the status,

 # nova list

Here it is showing Flavor-2

I checked in dashboard there also it is showing updated one (Flavor-2), but when i login to VM instance and checked filesystem

 # df -h

here filesystem is showing Flavor-1 (memory resource), RAM size is updating but harddisk is not updating. Need any one help to fix this issue.

It is not possible to downgrade the disk size of instance from higher to lower size in my knowledge whereas you can change at the cpu level.

here your flavor 1 has 25 Gb Disk and flavor 2 has 10Gb Disk. So in this case it won't work as expected when you resize the instance.

Thanks, Anand

Thank you for your response. But when i resize instance (flavor-1 to flavor-2) 25 to 10GB disk in Dashboard/CLI status is showing flavor-2 details. As per general scenario i will accept ur answer. But why dashboard and CLI status size showing updated flavor. Was it bug?

It's possible that your disk has been resized, but the partition table hasn't been updated, so it's still reporting the previous size ? Using fdisk and you see the details of the disk now connected to the machine ??
