Hi, After upgrading to kernel 3.17 btrfs send has stopped working.
ERROR: send ioctl failed with -5: Input/output error The following message is printed by kernel: [75322.782197] BTRFS error (device sda2): did not find backref in send_root. inode=461, offset=0, disk_byte=1094713344 found extent=1094713344 btrfs inspect-internal inode-resolve -v 461 /u00/root.snapshot returns: /var/log/emerge-fetch.log After removing this file, the error moves on to another file. btrfs scrub output: scrub status for bc31b068-2c36-4ff2-ac5c-7ce55af5371d scrub started at Mon Oct 6 19:49:25 2014 and finished after 1748 seconds total bytes scrubbed: 94.21GiB with 0 errors Other then the btrfs send problem, the filesystem works normally. Is this a bug in btrfs-send or is my filesystem corrupted and should be restored from backup ? Please tell me if I can do anything else to help debugging this issue.
