[Bug 1212492] Re: cc_growpart broken if parted resizefs found

[Scott Moser]

I dont think i follow what you meant by "parse the output for the
warning and answer yes".

Example:
$ echo "1,1000,L" | sudo sfdisk /dev/vdb
$ grep "vdb" /proc/partitions 
 253       16   20971520 vdb
 253       17     504000 vdb1
$ sudo mkfs /dev/vdb1
$ sudo mount /dev/vdb1 /mnt

## now /dev/vdb is busy (mounted) try to resizepart on it.

$ sudo parted /dev/vdb resizepart 1 </dev/null
Warning: Partition /dev/vdb1 is being used. Are you sure you want to continue?
$ echo $?
1

# so that didn't resize (reading from /dev/null).  Not surprising. 
# try with 'Yes' to stdin.
echo "Yes" | sudo parted /dev/vdb resizepart 1; echo $?
Warning: Partition /dev/vdb1 is being used. Are you sure you want to continue?
1

I also failed in an attempt with 'expect', but not sure thats relevant
as I dont want to use expect anyway, and I might have done something
wrong.
