Hi. My system: - Fedora 28 x86_64 - kernel-4.17.7-200 - btrfs-progs-4.15.1-1 The command 'btrfs subvolume sync -s 2 xyz' hangs in this case: - Run command 'btrfs subvolume sync -s 2 xyz' . - After some time the kernel reports an error on the filesystem. (error that existed before the command was launched.) - The filesystem goes in read-only mode. - The command hangs. Best regards. gdb -- 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
