freenas import pool error corrupted data

[modirandev]

Hello friends
I have a FreeNAS server that has been working for about a year without any problems. After a power outage, I had a problem that I am presenting here.
After this incident, the boot server had a problem and I solved the problem with instructions in this forum, but still the operating system did not run properly.
I had to install a new FreeNAS on another hard drive and connect the previous server data drives to it.
The important thing is that the space defined in the previous server was not encrypted.
Now in the new server, when I want to import this space, I see the following error.

And when I enter this in the commands related to the server for import this poll, the output is like this.

I also got help from the instructions on this page, but I did not succeed:

Thank you for your help to solve this problem

and try this commands with outputs :

root@freenas[~]# zpool import -f -F ContentPool
This pool uses the following feature(s) not supported by this system:
com.delphix:log_spacemap (Log metaslab changes on a single spacemap andflush them periodically.)
org.zfsonlinux:userobj_accounting (User/Group object accounting.)
org.zfsonlinux:project_quota (space/object accounting based on project ID.)
All unsupported features are only required for writing to the pool.
The pool can be imported using '-o readonly=on'.
cannot import 'ContentPool': unsupported version or feature

root@freenas[~]# zpool import -f -F -o readonly=on ContentPool

Destroy and re-create the pool from
a backup source.
