Hi!
With my setup, when I copy a 500MB file from the Gluster mount to local
disk it takes about 6-10 times longer than disk to disk. When I
investigate it further, I see huge amounts of data between my two
gluster servers. Is this the way gluster should work? I thought it just
checked meta-data on the other server, it should not copy the entire
file from the other server?
My client config is the same on both servers:
volume global1
type protocol/client
option transport-type tcp
option remote-host 10.10.10.20
option transport.socket.nodelay on
option transport.remote-port 6996
option remote-subvolume brick2
end-volume
volume global2
type protocol/client
option transport-type tcp
option remote-host 10.10.10.21
option transport.socket.nodelay on
option transport.remote-port 6996
option remote-subvolume brick2
end-volume
volume mirror-0
type cluster/replicate
subvolumes global1 global2
end-volume
volume writebehind
type performance/write-behind
option cache-size 10MB
subvolumes mirror-0
end-volume
volume iocache
type performance/io-cache
option cache-size 1GB
option cache-timeout 5
subvolumes writebehind
end-volume
volume quickread
type performance/quick-read
option cache-timeout 5
option max-file-size 1024kB
subvolumes iocache
end-volume
volume global
type performance/stat-prefetch
subvolumes quickread
end-volume
