I send snapshot from backup volume, and send new snaopshot to backup volume, and some file lost in received volume. In detail: 1. Host A has new Btrfs volume and Host B have two backuped readonly subvolumes (190312-010100, 190315-001000). 2. Host B send 190315-001000 subvolume to Host A. 3. Host A completely received (all files exist.) 4. Host B took new readonly snapshot "back1" on 190315-001000 (all files exist.) 5. Host B send back1 with `-p 190315-001000` to Host A (some file lost.) 6. Host B took new read-writable snapshot "world" on back1 (all files exist.) 7. Host B modified world. 8. Host B took new readonly snapshot "back2" on world (all files exist.) 9. Host B send back2 with `-p 190315-001000` to Host A (some file lost.) 10. Deleted received snapshot and Host B send back2 with `-p back1` to Host A (some file lost.) Kernel 5.0.5-1-MANJARO Btrfs progs btrfs-progs 4.20.2-1 What I should do? Thanks. Masaki Haruka
