New kernel available for testing

Hi,

We're readying a new OF release and have worked up an updated kernel
that integrates all the external modules that were once shipped separately.

PROCEED WITH CAUTION. ONLY INSTALL IF YOU ARE INTERESTED

There are also some nifty new integrations such as FC target support and something from SGI called Comprehensive System Accounting (CSA). You can learn more about tha t here:

http://oss.sgi.com/projects/csa/


CSA might not mean much to you if you're running Openfiler in a small network, but for larger setups, it allows you to bill individual users/groups based on their re source usage profile. If you want to play around with CSA you'll also need to install the userland components:

1) conary update job=openfiler.rpath.org@rpl:1-contrib
2) conary update csa=openfiler.rpath.org@rpl:1-contrib
3) conary update info-csa=openfiler.rpath.org@rpl:1-contrib

Also integrated is SCST and iSCSI-SCST which we might use to replace IET in the future. Details for both are here:

http://scst.sourceforge.net/

If you wish to play around with FC target support (you'll need an Qlogic FC controller):

1) conary update scst=openfiler.rpath.org@rpl:1-contrib --no-deps
2) service scst start
3) then run scstadmin for instructions

If you have an Qlogic FC controller, please go ahead and use the isp_mod kernel module (in place of qla2xxx). We're especially interested in how that performs under load.

caveat emptor: isp_mod seems to hang the system on some configs. So you could try the alternative qla2xxxt module which is the standard qla2xxx with target mode suppo rt patched in. I've renamed it to qla2xxxt so that you can have both the original qla2xxx and the integrated target support qla2xxxt linked into the kernel concurrently.

To enable FC target support for a qlogic HBA:

1) Edit /etc/modprobe.conf
2) map qla2xxxt to your FC HBA (eg. alias scsi_hostadapter qla2xxxt)
3) echo "1" >/sys/class/scsi_host/host0/target_mode_enabled

Updating to the new kernel will also require an update to the iSCSI
target userland component:

1) conary update iscsi_trgt

Please provide feedback via this mailing list or the bug tracker:
https://project.openfiler.com/tracker/newticket

So without further ado:

conary update kernel:runtime=openfiler.rpath.org@rpl:kernel-test
