The three archives can be found at the same location: http://linux-iscsi.org/builds/VHACS-VM/x86_64/vmware6/ II) lio-core-2.6.git has been updated to v2.6.26 and loaded successfully on 32-bit x86 VM. Only a very minor change to get things compiled on v2.6.26. Please see http://git.kernel.org/?p=linux/kernel/git/nab/lio-core-2.6.git;a=summary for more information. III) VHACS-VM has now successfully been able to handle node failures and restart failed cluster resource allocations (RA) on the active node, across multiple platforms using x86_64 hardware virtualization. :-) Lots of things going on this week. More to come soon. Please keep checking the http://Linux-iSCSI.org site for the latest information. Many thanks for your most valuable of time, --nab On Mon, 2008-07-14 at 11:02 -0700, Nicholas A.
