Hello, I have a problem and could not find a solution yet. I would like to hear you opinion. I have 2 machines, machine A and machine B. They are mail servers serving with Maildir. I need to find out a solution where I can do balancing between server A and B while in production, and, if one of the nodes get down, only the other one will do the work of both. The main problem I find is a solution regarding the information (data stored). Right now I have it running with NFS on a third machine, machine C for example. I know machine C is a SPOF but it is acceptable. The big problem is performance. NFS is going away on huge load. I did ggate0+local disc RAID 1 with gmirror. Sincronization on writing works perfectly but I can not mount the same disk locally while exporting it via ggated. Why cant I mount it? Anyone knows? If I could, eliminating the SPOF would be very easy. Performance would be great too because ggated performance is way better than NFS on this kind of operations, specially because READ operations can be done on a local disk (priority configured via gmirror). Any idea on how to setup this enviroment?
