iSCSI initiator iqn
by Raghu
Hi,
I could not find any option to set iSCSI initiator iqn while using
guestfish, although the underlying qemu command has this option.
It appears that each time guestfish tries to connect to iSCSI LUN, a
randomly generated initiator iqn is being used. This is preventing
guestfish to connect to the iSCSI target in our environment as the target
allows incoming connection based on the preconfigured initiator iqn.
Is there way to set iSCSI initiator iqn with guestfish command?
Regards
Raghu

For comparison, here is the output using ntfs-3g-2014.2.15-1.fc20.x86_64:
$ guestfish -N fs:ntfs exit
$ virt-rescue --ro -a test1.img
[...]
><rescue> ntfsresize --check /dev/sda1
ntfsresize v2014.2.15 (libntfs-3g)
><rescue>
So that's basically the same as your output, and indicates that
the ntfsresize command itself is working.
Now you should try actually resizing the partition in virt-rescue.
Since it is inside ``virt-rescue --ro'' it won't actually alter the
disk image -- the ``--ro'' flag means that libguestfs puts a
protective overlay between the commands in the rescue shell and the
underlying disk image.
Here is what happens for me:
><rescue> ntfsresize /dev/sda1
ntfsresize v2014.2.15 (libntfs-3g)
Device name : /dev/sda1
NTFS volume version: 3.1
Cluster size : 4096 bytes
Current volume size: 104727040 bytes (105 MB)
Current device size: 104727040 bytes (105 MB)
New volume size : 104727040 bytes (105 MB)
Nothing to do: NTFS volume size is already OK.

[PATCH] generator: Sort the structs.
by Richard W.M. Jones
Sort the structs when generating code. Since the structs are
logically indepedent of each other, this should have no effect except
to make generated files list the structs in a different order.
However this also fixes the following build problem:
File "convert_linux.ml", line 322, characters 43-50:
Error: This expression has type G.stat = Guestfs.stat
but an expression was expected of type G.dirent = Guestfs.dirent
It turns out the OCaml bindings don't like the fact that we have
two structs with a common field name (dirent.ino and stat.ino).
In OCaml < 4.01, this means that any attempt to reference stat.ino
would fail because dirent.ino appears second in the file, overriding
stat.ino.
In OCaml >= 4.01 the compiler now uses some disambiguation rules based
on the known types to resolve this problem.
