Title:
resize revert will let new data lost
Status in OpenStack Compute (nova):
New
Bug description:
* description:
Hi all，I found a serious problem in revert resize action for a vm. the
revert resize operation will let the increments data lost. the reproduction
steps show below.
* Step-by-step reproduction steps:
1、 create a new vm， which flavor choice C1-R2-D10（Core：1， Ram： 2G， Disk：10），
image：centos 76
2、login the vm, and touch a new file: 1.txt, and write some message to
the file. like: echo 'aaa' > 1.txt
3、do resize operation for the vm. change flavor to C2-R4-D20. but do
not confirm or revert the operation now.
4、login the vm again, and touch another new file: 2.txt, and write
some message to the file. like: echo 'bbb' > 2.txt
5、now we do revert-resize operation, revert the resize operation which
in 2 step.
6、when the revert resize done, login in the vm, and we will found the
2.txt will lost.
* Expected output:
I think the increment 2.txt added between do resize and revert
should be preserved.
* Actual output:
but the 2.txt lost ！！
* Version:
** OpenStack version： Rocky
** Linux distro, kernel. CentOS Linux release 7.8.2003
(Core)、3.10.0-1127.el7.x86_64
