[Gluster-users] UCARP with NFS

[anthony garnier]

Hi all,

I'm currently trying to deploy ucarp with GlusterFS, especially with nfs access.
Ucarp works well when I ping the VIP and i shutdown Master (and then when the Master came back up),but I face of a problem with NFS connections.

I got a client mounted on the VIP, when the Master fall, the client switch automaticaly on the Slave with almost no delay, it works like a charm. But when the Master come back up, the mount point on the client freeze.
I've done a monitoring with tcpdump, when the master came up, the client send paquets on the master but the master seems to not establish the TCP connection.


My  volume config : 

Volume Name: hermes
Type: Replicate
Status: Started
Number of Bricks: 2
Transport-type: tcp
Bricks:
Brick1: ylal2950:/users/export
Brick2: ylal2960:/users/export
Options Reconfigured:
performance.cache-size: 1GB
performance.cache-refresh-timeout: 60
network.ping-timeout: 25
nfs.port: 2049

As Craig wrote previously, I well probed hosts and created the volume with their real IP, I only used the VIP with the client.

Does anyone got experience with UCARP and GlusterFS ?
