Re: Is anyone using btrfs send/receive howto?

I read different howtos on the wiki and oracle docs, but I can't get it
to work:

legolas:/mnt/btrfs_pool1# btrfs subvolume snapshot -r tmp tmp_read_only_new
Create a readonly snapshot of 'tmp' in './tmp_read_only_new'
legolas:/mnt/btrfs_pool1# sync
legolas:/mnt/btrfs_pool1# btrfs send tmp_read_only_new | btrfs receive /mnt/btrfs_pool2/
At subvol tmp_read_only_new
At subvol tmp_read_only_new

# Make a new snapshot later and try to sync it:
legolas:/mnt/btrfs_pool1# mv tmp_read_only_new tmp_read_only
legolas:/mnt/btrfs_pool1# btrfs subvolume snapshot -r tmp tmp_read_only_new
Create a readonly snapshot of 'tmp' in './tmp_read_only_new'
legolas:/mnt/btrfs_pool1# btrfs send -p tmp_read_only  tmp_read_only_new | btrfs receive /mnt/btrfs_pool2/
At subvol tmp_read_only_new
At snapshot tmp_read_only_new
ERROR: creating snapshot tmp_read_only_new -> tmp_read_only_new failed. File exists

This is where I get stuck:
Obviously /mnt/btrfs_pool2/tmp_read_only_new already exists since it's the reference backup volume.

What am I doing wrong?

Thanks,
Marc
