[Gluster-devel] what am i missing here? (fast transfer only through 1 client) |

Any help is greatly appreciated:
server 1 - 1Gbps & identical hardware
server 2 - 1Gbps & identical hardware
both have identical client & server conf files w/ performance enhancement
and afr
the clients are run to mount to the same file path on both servers.
now, scping a file from local file system on server1 to mounted gluster fs
on server 2 transfers at ~3MB/s
scping a file from local file system on server2 to mounted gluster fs on
server1 transfers at ~23MB/s
ALSO, scping to non-glusterfs yields ~23MB/s from server1 to server2 and
vise versa, so something with gluster that is bottlenecking at 3MB/s
If I change the afr section of the client files to list "subvolume brick1
brick2" to "subvolume brick2 brick1", the transfer rates above switch - now
server 1 to server 2 is fast and server 2 to server 1 is slow.
volume afr
type cluster/afr
subvolumes brick1 brick2
option self-heal on
end-volume

------
volume afr
type cluster/afr
subvolumes brick2 brick1
option self-heal on
end-volume
/var/lib/data is the mounted file system from glusterfs-client.vol
address@hidden:/var/lib$ scp /tmp/2.mpg address@hidden:/var/lib/data/
2.mpg 14% 62MB 2.4MB/s 02:34
ETA
Now, the other way:
address@hidden:/tmp$ sudo scp 3.mpg address@hidden:/var/lib/data/
3.mpg 100% 71MB 23.6MB/s 00:03
