Dear ON Developers,
Our ON configuration is a bit different from what ON manual assumes.
The following is my guess of how onevm cancel VM where this VM is from a
persistent image and running in a host via shared transfer manager.
I believe the following two variables are assumed in ON standard deployment.
SRC=$IMAGE_REPOSITORY_PATH/
DST=$VM_DIR/vmid/images
In this case, onevm cancel will do
1. tm_mv.sh : mv $DST/disk.0 /var/log/one/vmid/disk.0
Note here that $DST/disk.0 is actually a link to
$IMAGE_REPOSITORY_PATH/original_file
2. tm_delete.sh : rm –f $DST
3. Image Driver will invoke var/remote/image/fs/mv to try to
/var/log/one/vmid/disk.0 to the same image in IMAGE_REPOSITORY_PATH
which will not happen because Image Drive will realize that these two are
identical when running readlink command.
My guess is that, if this is true, this step 3 appears to be a bug.
In other words, in step 3, the mv should not be prevented because they have
the same pathname.
Could ON developers check this?
(I might be wrong.)
Thank you.
