Description Richard W.M. Jones 2010-11-26 09:39:46 UTC 
+++ This bug was initially created as a clone of Bug #657472 +++

Description of problem:
Specifying an unknown check sum type in the checksum API causes the umount/umount-all to fail.

Version-Release number of selected component (if applicable):
libguestfs-1.6.2-4.el6.x86_64

How reproducible:
100%

Steps to Reproduce:

$ guestfish -a test.img
...
><fs> checksum blabla /test 
libguestfs: error: checksum: unknown checksum type, expecting crc|md5|sha1|sha224|sha256|sha384|sha512

><fs> exit
libguestfs: error: umount_all: umount: /sysroot: umount: /sysroot: device is busy.
        (In some cases useful info about processes that use
         the device is found by lsof(8) or fuser(1))


Expected results:
no failure when exit or umount.

---------------------------

Simple reproducer from the command line:

$ guestfish -N fs -m /dev/sda1 touch /test : checksum blabla /test
libguestfs: error: checksum: unknown checksum type, expecting crc|md5|sha1|sha224|sha256|sha384|sha512
libguestfs: error: umount_all: umount: /sysroot: umount: /sysroot: device is busy.
        (In some cases useful info about processes that use
         the device is found by lsof(8) or fuser(1))

I assume this in the currentrelease, given that it's been in modified for 1.5 years :)
