ATTENTION LUSTRE USERS:
Lustre 1.2.7 has been released!

Lustre 1.2.7 contains numerous recovery fixes over Lustre 1.2.6 but is =
only
a recommended update for users of Lustre on Linux 2.4.  Please read =
below
for details.

Noticeable improvements allow Lustre 1.2.7 to:

- avoid deadlock during client->OST recovery handling

- avoid allocating new objects on OSTs that are full

- use priviledged source ports for client->{MDS,OST} connections,

It's important to note though that the privileged port change means it =
is
necessary to update the clients before, or at the same time as the =
server.
It is not possible to update only the servers without a configuration
change.  In all cases CFS recommends that both the clients and servers =
are
updated at the same time.

- deny non-priviledged connections at server by default

- rate-limit console error and warning messages

- handle mmap()ed regions coherently, by using the Lustre DLM.  This =
will
correct the "Bus error" symptom occasionally seen when running modified
binaries from Lustre.

--> Linux 2.6 users: please note that the mmap fixes are not complete, =
and
that Lustre 1.2.7 modules will not load in 2.6 kernels.  Please continue =
to
use 1.2.6 until the release of Lustre 1.2.8, which will correct this =
issue:

A complete list of changes/improvements can be found at
http://www.clusterfs.com/changelog.html

Lustre 1.2.7 RPMs are available immediately to customers with a CFS =
support
contract, and will be made available to the general public within 12 =
months.

releases and expert CFS file system support, CFS support customers gain
