I'm hoping someone can help me, trying to recover a btrfs pool, that lost 1st drive. I tried to mount the 2nd drive and I've been having fs errors.

I got the 1st drive readable again, but it appears that it lost the filesystem, but it has not been formatted. Neither have.

Please can anyone help?

devices:

  • /dev/nvme0n1p1
  • /dev/nvme1n1p1
root@blaster:~# btrfs rescue super-recover -v /dev/nvme0n1p1
No valid Btrfs found on /dev/nvme0n1p1
Usage or syntax errors
root@blaster:~# btrfs-find-root /dev/nvme0n1p1

All Devices:
        Device: id = 1, name = /dev/nvme1n1p1

Before Recovering:
        [All good supers]:
                device name = /dev/nvme1n1p1
                superblock bytenr = 65536

                device name = /dev/nvme1n1p1
                superblock bytenr = 67108864

        [All bad supers]:

All supers are valid, no need to recover
