. That's why at first I said it was a half-written separation. Another drawback is that although two read replicas are configured, each time a read-only replica with a high priority is provided with a read-only connection, only the high-priority read replica fails to be routed to the next read replica. This means that only 2 copies are currently available for read and write operations, and that the load balancing of read operations is not available between multiple read replicas.Building and joi

Part 3: detach a virtual disk using truecrypt Mount
After a virtual disk is loaded, you can create a file protected by the encryption of the virtual disk, and then uninstall the virtual disk. The created file is encrypted and stored in the encrypted volume. This step is relatively simple, how is truecrypt actually implemented?
Another core function of truecrypt is the unmountvolume function for detaching a virtual disk. It accepts three functions: the

This method deletes all matching elements from the DOM.
Note:the Detach () method does not remove the matching elements from the jquery object, so you can use these matching elements in the future, and unlike remove (), all bound events, additional data, and so on wi
