Hi
Me again with my afr question.
I want use afr for making my cluster node_down_proof.
My cluster is not for storage but for computation. It's for this reason if
a node is down we can allow the data on this node is not accessible (event
lost).
But I want when one node is down the other node work fine.
For this reason I use afr with two replication (and now with Arnand Avati
it's working). But what's I don't understand is when I make one node (where
is the namespace) down (by using /etc/init.d/glusterfs-sserver stop)if I'm
on one node I can access the data (not on the down node off-course), but I
can make «ls» or sometime «cd».
This my config
volume node0-ns
type protocol/client
option transport-type tcp/client # for TCP/IP transport
option remote-host node0
option transport-timeout 30
option remote-subvolume name-space
end-volume
volume node1-ns
type protocol/client
option transport-type tcp/client # for TCP/IP transport
option remote-host node1
option transport-timeout 30
option remote-subvolume name-space
end-volume
#
# Definition des namespace via afr
#
volume name-space
type cluster/afr
option replicate *:2
subvolumes node0-ns node1-ns
end-volume
#
# Definition du premier unify
#
volume unify
type cluster/unify
subvolumes node0 node1 node2 etc...
option scheduler nufa
option nufa.local-volume-name quadri11
option nufa.limits.min-free-disk 10%
option namespace name-space
end-volume
Regards.
