[Bug 236640] Re: iSCSI install fails under hardy

[Etienne Goyer]

As I explained a couple months earlier (see comment 2), even if the path
to iscsi-iname is fixed, it still fail in the end.  The installer goes
on just fine, but if you choose to configure a file system residing on
an iSCSI target to be mounted at boot time (not as the root file system,
just about any mount point), /etc/rcS.d/S30checkfs.sh will fail at boot
and drop to a maintenance shell.

This is because the iSCSI block device is not brought up on boot
correctly, and as such the file system residing on that iSCSI target
cannot be checked/mounted.  For it to be so, there need to be a valid
node configuration file under /etc/iscsi/nodes/.  This configuration
file is being generated just fine by the open-iscsi udeb in the
installer environment.  However, it is *not* being copied to the root
file system of the installation (/target).  There are two problems:

1. The post-installation script of the udeb (debian/open-iscsi-udeb
.finish-install in the source deb) is being installed in /lib/finish-
install.d/.  I think this is supposed to be /usr/lib/finish-install.d/.

2. There is a bug in debian/open-iscsi-udeb.finish-install.  It copy the
whole configuration directory with:

    cp -a /etc/iscsi /target/etc/iscsi

Which mean we end up with the installer iscsi configuration directory as
/etc/iscsi/iscsi in the target, which is not what we want.  I presume it
should really be:

    cp -a /etc/iscsi /target/etc/

So that we have the configuration from the installer environment copied over to the target properly.
 

The above problems where found on both hardy and jaunty.


Moreover, there seems to be a race condition at boot time where open-iscsi is started before networking is ready, which also prevent the iSCSI block device to be available when /etc/rcS.d/S30checkfs.sh is being run.  I am still investigating and will report a separate bug as appropriate.
