[one-users] Image mgmt on ONE 3 beta : issues

[Robert Parrott]

Hi All,

I'm working with ONE 3 beta, and am having issues with image mgmt. In
one case, trying to delete or add an introduced image doesn't work,
and in another case, using the "onevm saveas" command breaks. I'm
seeing this in both the 2.9.80 pre-release and the latest git pull of
the master branch.

In both cases, it appears as if helper scripts that are supposed to be
in the directory

   $ONE_LOCATION/var/remotes/image/fs

named "mv" or "rm" (etc.) are not actually there; in fact, the entire
$ONE_LOCATION/var/remotes/image directory is missing. I expect that
something in the new IMAGE_MAD setup -- in oned.conf -- is the cause.
either a missing configuration or a bug. My IMAGE_MAD stanza is


  IMAGE_MAD = [ executable = "one_image", arguments  = "fs -t 15" ]

and the one_image scripts and everything are stock. Also, we are using
shared NFS filesystem across the board. In looking at the one_image.rb
code, I see where scripts from the $ONE_LOCATION/var/remotes/image/fs
are invoked, I just don't understand how they get populated.

Any help in resolving this would be appreciated.  A sample log snippet
of a failed insert and a failed delete is below.

Thanks,
Rob
