Hi Bipin,

I have four hosts with replica 2. If any of the host goes down among these 
four, client operations will hang. And it is not exactly network ping timeout, 
it is ping timeout + ~20seconds.

I assume that this is because the host which went down is even the host which 
is used for mounting client.

Suppose there are 2 host. Host1 and Host2. And client is mounted as
mount -t glusterfs host1:brick1 /mnt

In this case if host1 goes down, client will wait till network ping timeout 
before it starts accessing volume using other host(host2).

So I think this is expected behaviour.

Thanks,

Hello,

I am running gluster storage in distributed replicated mode. When one of the 
brick (host) goes offline, operations on the file system by the client will 
hang for a while and resumes after sometime. I searched and found that 
operations hang for the period set in network.ping-timeout.
Can anyone explain me why the client operations will hang even though the other 
brick is available with all the data?
