Hi, I have a SAN with 4 file systems on it, each GFS. These are mounted across various servers running GFS, 3 of which are lock_gulm servers. This is on RHEL WS 3 with GFS-6.0.0-7.1 on x86_64. One of the file systems simply will not mount now. The other 3 mount and unmount fine. They are all part of the same cca. I have my master lock server running in heavy debug mode but none of the output from lock_gulmd tells me anything about this one bad pool. How can I figure out what is going on, any good debug or troubleshooting steps I should do? I think if I just reboot everything it will settle down, but we can't do that just yet, as the master lock server happens to be on a production box right now. Also, is there a way to migrate a master lock server to a slave lock server? In other words, can I force the master to become a slave and a slave to become the new master? Thanks!
