[Gluster-users] gluster + interruptions causing high load
Hello again, I am now seeking some advices regarding gluster configuration. I have the following options: Options Reconfigured: nfs.disable: 1 network.ping-timeout: 1>From my tests, I noticed that setting a low network.ping-timeout (1s)causes gluster to declare the other node dead, and quickly allow access to the common storage content. But in the last 4 days I have been experiencing some weird occurrences. I am using gluster in WAN environment replication, and I am suspecting network connectivity is sometimes timing out. This causes gluster to stall for ~ 1 minute, like the log says: [2012-04-21 18:11:31.758139] C [client-handshake.c:121:rpc_client_ping_timer_expired] 0-comun-vol-client-0: server xxx.xxx.xxx.xxx:24009 has not responded in the last 42 seconds, disconnecting. and also causes big load on the server (100+), freezing all other applications. I have now reconfigured network.ping-timeout to 10. What I would like to achieve is to have minimum "downtime" when bricks are failing. Any other options I can set? -------------- next part -------------- An HTML attachment was scrubbed...
