fsck.auto: No such file or directory So I'm trying to run fsck on my sdcard's ext4 partition and it doesn't work for some reason.

sh-4.1# fsck /dev/block/vold/179:2
fsck (busybox 1.21.0-Stericson, 2013-01-28 21:49:55 GMT)
fsck: fsck.auto: No such file or directory


Any idea why is says "No such file or directory"?
You likely need to include the util-linux-fsck package into your busybox image. The warning is saying that there is a file missing which the util-linux-fsck package provides.
