Re: [ogfs-users]opengfs + opendlm question
Today I fired up opendlm and tried it out with openais
(developer.osdl.org:/dev/openais). I wanted to see if I could setup
opengfs to use opendlm and openais.
I got opendlm to link with openais (and appear to work) with some
hacking. I can give out the patches if anyone wants to try it, but its
not meant for general consumption. I started it and it eventually
printed out the error:
[root@persist dlmdu]# Condition timeout, last cluster event [300]
seconds ago.
Any ideas what this means?
I tried some of the user/tests programs but I wasn't sure what to expect
so I can't tell if they worked or not.
Thanks
