[Gluster-users] GlusterFS Storage Interruption at Node Loss
Hello list! I am experiencing an issue whereby mounted Gluster volumes are being made read-only until the network timeout interval has passed or the node comes back online. I have reduced the network timeout to one second and was able to reduce the size of the outage window to two seconds. I am curious if anyone else has seen this issue and how they went about resolving it for their implementation. We are using a distributed-replicated volume, but have also tested _just_ replicated volume with the same results. I can provide the gluster volume info if it's helpful, but suffice to say that it is a pretty simple setup. Thanks! -- Nic Seltzer Esports Ops Tech | Riot Games Cell: +1.402.431.2642 | NA Summoner: Riot Dankeboop http://www.riotgames.com http://www.leagueoflegends.com -------------- next part -------------- An HTML attachment was scrubbed...

Nic I believe this is normal expected behaviour. The network timeout is there because it is expensive to tear down the sockets etc. so you only want to do it if a node has really failed and not for some transitory network blip.
