Panic Output

Expected Behavior

• The creation time should be synced with the terraform creation time.
• The requested instance count, should sync with the amount of read-only instances when it is checked in the console.

Actual Behavior

• If creation time only needs 10 mins, the terraform creation time does not need to wait until 15 mins then lock timeout.
• The requested instance count doesn't sync with the number of read-only instances when it is checked in the console.

Steps to Reproduce
