RE: [Gluster-devel] 1.4.0 and HA Translator

[Melvin Wong]

Hi Raghavendra,

Tks for the quick reply. Another question is do you know if Heatbeat is better choice or HA translator for failover. When we use HA translator, what will happen to the open files or current file transfer during a failover? Will the clients clashes while  trying to connect to the slave server?

Thank you.

Hi Melvin,
I meant HA is also designed to help server side afr setups you've explained. Sorry for the typo.

Hi,

I will like to know is there a need to upgrade my current setup from glusterfs-1.3.11 to 1.4.0rc6. What major bug fixes are there in 1.4 since 1.3.11? Also, currently my setup consist of 2 glusterfs servers mirroring each other with AFR. One of the server is set as master where all the clients are connected to it. We maintain HA by using Heartbeat on the 2 servers. Once the master server fails, heartbeat will failover to the slave server. However, occasionally the clients might encounter problems connecting during the failover or the 2 servers no longer  able to replicate well. Could HA translator in 1.4 be of help to replace the Heartbeat? Will it be more stable than Heartbeat during a failover?
