Gorka Eguileor a6e789f27e Fix iSCSI multipath rescan 
iSCSI multipath rescan uses iscsiadm --rescan option for nodes and
sessions, which can end up recreating devices that had just been removed
if there's a race condition between the removal of a SCSI device and the
connection of a volume.

The race condition happens if a rescan done when attaching happens right
between us removing the path and removing the exported lun, because the
rescan will add not only the new path we are attaching, but the old path
we are removing, since the lun still hasn't been removed.

This would leave orphaned devices that unnecessarily pollute our
environment,

This patch narrows the rescan to only rescan for the specific target id,
channel, and lun number if we can find this information.

When we cannot find this information we do the scan as we were doing it
before.

OpenStack Cinder brick library for managing local volume attaches

Features

  • Discovery of volumes being attached to a host for many transport protocols.
  • Removal of volumes from a host.

Hacking

Hacking on brick requires python-gdbm (for Debian derived distributions), Python 2.7 and Python 3.4. A recent tox is required, as is a recent virtualenv (13.1.0 or newer).

If "tox -e py34" fails with the error "db type could not be determined", remove the .testrepository/ directory and then run "tox -e py34".
