Hi Christopher, I advise you to really try the most important part of your description you take for granted - the reconnect case. Our experiences are quite away from what you think is the worst case. You can easily check out what happens if you just pull the network cable 5 times in 10 minutes. We came to the conclusion that disconnect/reconnect should be avoided under all circumstances. Interestingly stopping one servers' glusterfsd and restarting it works out quite well in our setup. So offline-updating a server (which was our main purpose) is quite ok. -- Regards, Stephan On Thu, 18 Mar 2010 08:33:51 -0400 (EDT) Christopher Hawkins <chawkins@xxxxxxxxxxx> wrote: > I have a question re: ping timeout for any of the dev's. The minimum value is 5 and the max is 1013... But in my case, I use replicate to mirror server pairs that are each gigabit connected by crossover cables. The latency is very low. 5 seconds is a long time and personally I would like them to give up on the failed link after 500ms or so, so the mountpoint becomes available quickly to the remaining node. > > Or I would at least like to test it and see if it's stable that way; I don't mind getting disconnected early in the case of a slow server, because it will just reconnect when the server comes back. Is there any hope for being able to tweak this parameter? Or is there a reason why it simply cannot be lower than 5? > > Thanks for any insight and for glusterfs! > > Christopher Hawkins > > > _______________________________________________ > Gluster-devel mailing list > Gluster-devel@xxxxxxxxxx > http://lists.nongnu.org/mailman/listinfo/gluster-devel >
