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

*** 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.
