We tried the quorumd, and noticed that we had to rewrite principle parts of SF-EX. SF-EX which works as RA checks the lock status regularly. and quorum server module also go the round periodically. but it seems that quorumd_getquorum() starts up without any apparent connection to a quorum server. Maybe it's just as well we're going to implement some exclusive algorithms right there, it might be related to CCM problem, I'm not sure. If it's possible to handle this function as RA, could you consider introduction of SF-EX into the next release as the first step?
