[Solved]please help with btrfs read only filesystem

Yesterday I deleted a snapshot using the command

sudo btrfs subvolume delete /snapshot-2014-**-**

in which the snapshot-... is a snapshot I created eariler. But a few hours later I suddenly found that the file system became read-only. I reboot and the message stuck at mounting /dev/sda1 and failed, into an emergency shell, saying something like "no subvolume is find". I tried to mount /dev/sda1 using a rescue usb stick but still failed...
I have been using the same command to create and delete snapshots for several months without problem, but this time... I don't know what was I doing wrong, maybe I mistyped something this time?
So... How could I recovery the filesystem? I've searched for a bit but cannot find any satisfied result.

EDIT: I re-installed the system.
