[SSI-devel] Two node CI/2.6 cluster

[Brian J. W. <Bri...@hp...>]

Hi Aneesh,

Good news!! I found the deadlock that was preventing the second node 
from joining. Due to a locking change in flush_signals(), the icssvr 
daemon was attempting to grab the same spinlock twice with interrupts 
disabled. I removed the extraneous spinlock code from the CI wrapper 
function, and a two-node CI cluster now works! I even did a couple of 
CLMS master failovers.

The modified patch is available at
http://ci-linux.sourceforge.net/contrib/ci-2.6.6.ak.aug11.patch.bz2

I still need to review the changes you made to get CI/2.6 to build. I'll 
be on vacation until next Tuesday, so I'll review them after I get back. 
Then I'll create a new branch in the CI repository for this stuff.

Best regards,

Brian
