Welcome to the forums!

Hmmm. Not possible to decode your posting - no idea what it means. Please explain the situation in more detail. Best to follow the forum rules to get a good answer.

See "Forum Rules" in red above - updated list is here:

It's important to remember that hardware information is extremely important when diagnosing problems so please make sure to include this information if you need help troubleshooting a problem. This includes:​

• TrueNAS version
• Motherboard make and model
• CPU make and model
• RAM quantity
• Hard drives, quantity, model numbers, and RAID configuration, including boot drives
• Hard disk controllers
• Network cards

Please do as @Redcoat suggests, follow the forum rules and post the required information. Additionally your statement makes no sense to me. I suspect English is not your native language. Please try again and be as descriptive as possible. Understanding what your situation is will greatly help us provide you a good answer.

And welcome to the forums.
