You don't say here which version of btrfs-progs you are using... As Bob said, this issue is caused by a desynchronization between the state file on the drive and the kernel state. However, code was added to btrfs-progs 3.17 to detect and correct this condition. I'd suggest updating your btrfs-progs. -- Calvin Walton <calvin.walton@xxxxxxxxxx> -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
