Hi, I really enjoy the features of btrfs but send|receive is failing me so my backups are not working. I'm using "btrbk" to backup my drives (all local) and one of the three subvolumes errors out. When I run this command from the terminal it errors out: > btrfs send /mnt/ssd/_btrbk_snap/@.20151108 | btrfs receive /mnt/backup2tb/ At subvol /mnt/ssd/_btrbk_snap/@.20151108 At subvol @.20151108 ERROR: send ioctl failed with -2: No such file or directory ERROR: unexpected EOF in stream. The source is an SSD drive and the subvolume is a readonly snapshot of @. I have two other source subvolumes on another rotational disk that send|receive fine to the same target drive (/mnt/backup2tb) . There is plenty of space on the backup drive. The error happens after 110 seconds and the @.20151108 is 25GB. If the error happened at the end of the transfer it would be transferring at a rate of about 220MB/s. Since the receiving side is a slower rotational drive with a benchmarked write speed of 170MB/s I think the error is happening 80% of the way through the transfer. For versions, I'm using: - kernel 3.19.0-31-generic #36~14.04.1-Ubuntu SMP Thu Oct 8 10:21:08 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux - Linux Mint 17.2 (based on Ubuntu 14.04) which has a stock kernel of 3.17 (but I upgraded to 3.19). - btrfs-progs 3.19, 3.19.1 and 4.3 (all fail with the same error). I have high hopes for btrfs and want to help to make it better as an end user. When you have time can you please investigate this about a possible resolution? I can provide more details if needed. I appreciate the help.
