OK. I installed glusterfs-2.0.0rc on servers and client but If I changed
data on Client, data no chaged in two servers. Data changed on server1 only.
I need data changed on two servers when I changed data on client and when I
changed data on server1 or server2, changed data on other server and client.
My configuration:
###server1:
#execution command: glusterfsd -f
/usr/local/etc/glusterfs/glusterfs-server.vol
#file config:
volume brick
type storage/posix
option directory /home/export
end-volume
volume server
type protocol/server
option transport-type tcp/server
subvolumes brick
option auth.ip.brick.allow * # Allow access to brick
end-volume
###server2:
#execution command: glusterfsd -f
/usr/local/etc/glusterfs/glusterfs-server.vol
#file config:
volume brick
type storage/posix
option directory /home/export
end-volume
volume server
type protocol/server
option transport-type tcp/server
subvolumes brick
option auth.ip.brick.allow * # Allow access to brick
end-volume
###client:
#execution command: glusterfs -f
/usr/local/etc/glusterfs/glusterfs-client.vol /mnt/glusterfs
#config file:
volume brick1
type protocol/client
option transport-type tcp/client # for TCP/IP transport
option remote-host 192.168.240.227 # IP address of server1
option remote-subvolume brick # name of the remote volume on server1
end-volume
volume brick2
type protocol/client
option transport-type tcp/client # for TCP/IP transport
option remote-host 192.168.240.228 # IP address of server2
option remote-subvolume brick # name of the remote volume on server2
end-volume
volume ha
type cluster/ha
subvolumes brick1 brick2
end-volume
Regards and thanks for help ;)
