Couldn't read tree root BTRFS - SEED

Hello,
I have a problem when mounting the btrfs system with two units (one in SEED 
mode and the other in read-write mode)
 
Initially it is functioning correctly in production:
 
btrfs fi sh 
Label: 'SEED_MD2'  uuid: 285b16fa-b297-43ed-bb3b-311950729eb6 
       Total devices 2 FS bytes used 2.00TiB 
       devid    1 size 5.44TiB used 1.97TiB path /dev/bcache1 
       devid    2 size 1.80TiB used 119.03GiB path /dev/bcache0 
 
Label: 'BOOT'  uuid: ce8fd2ef-975c-417a-b90c-280f8d324c44 
       Total devices 1 FS bytes used 536.86MiB 
       devid    1 size 1.86GiB used 1.15GiB path /dev/md1 
 
Label: 'SEED_MD2'  uuid: 851e4474-d375-4a25-b202-949e51f05877 
       Total devices 1 FS bytes used 1.94TiB 
       devid    1 size 5.44TiB used 1.97TiB path /dev/bcache1
 
The bcache0 and bcache1 units are what I mention.
bcache1 is the SEED
bcache0 is the read-write
 
When it comes to mounting the two copy mirror devices that is in production I 
have this result:
 
parent transid verify failed on 2184045428736 wanted 269593 found 266275

       devid    2 size 1.80TiB used 102.03GiB path /dev/bcache2 
       *** Some devices missing
 
Would there be any way to tell BTRFS that the missing unit is the one that 
corresponds to the SEED unit so that it correctly rebuilds the file system?

Thank you.
