Unable to update instance (read replica which the creation was failed )

[yatabe]

1. I start to create a replica
2. the creation was failed because of "Couldn't find free blocks in allocated IP ranges."
3. the replica instance exists with the error, not disappeared.
4. I changed the private network of master instance from default to another.
5. the creation of replica was restarted.
6. the creation of replica was failed with unknown error.
7. the status of the replica instance is MAINTAINED now.
8. the, I cannot update both replica and master any more.

I want to delete the replica instance because I cannot update the master instance. But I cannot delete it, so what should I do? my company's support plan is BASIC, so I cannot get the tech support....

please

Hi, Yatabe,

Your project would need to be inspected by support.

This can be done over a support case under a valid business justification.

thank you for your replay.
I did not know the way of the support case.

I had given up solve this problem, and left it.
After 48hours, I found the replica was created and the status is normal now.
I did not notice when it is solved, but it took long time.

Now, both instance is under default network.
I tried to change the private network connection of master instance many times, but all attempts were failed by the replica was under MAINTINED.
I do not know how the private network connection of master instance have changed to default from another which I changed to.

Actually, To solve this problem, I tried many things and then I add allocated IP ranges to "private connection to service" named "cloudsql-mysql-googleapis-com" of default network.
Did It affected something of the replica creation??

Hello yatabe,

As an alternative to find a root cause, you can create a Public Issue Tracker (instructions here) if you don't have access to create a Support Case with GCP through the console. Please click here and fill the form.
