Disk structure under /mnt2 and replication question

Thanks for providing your thoughts on this. I did notice that difference, but assumed that, while a symptom of something not working, it wasn’t at the core of failure after the third replication (or at least I think so).

I added the force flag in btrfs.py on the receiver side here:

def set_property(mnt_pt, name, val, mount=True):
    if mount is not True or is_mounted(mnt_pt):
        cmd = [BTRFS, "property", "set", mnt_pt, name, val]
        return run_command(cmd)

like this:

def set_property(mnt_pt, name, val, mount=True):
    if mount is not True or is_mounted(mnt_pt):
        cmd = [BTRFS, "property", "set -f", mnt_pt, name, val]
        return run_command(cmd)

but that provided an error unfortunately. Interestingly, when I copied the command string printed in the error log exactly how it was captured, it worked, so not sure what happened. I will try again differently
