Hi!
I have two AiX hosts (TL5.3-05), connected using 2 GigaBit Eth cards configured in EtherChannel.
I want to use an NFS mount to share some disk space on node2 to accomodate oracle backups in. The NFS sharing was successful using the following parameters:
Also the NFS mount on node1 was successful:
node1: NFS client. The options are needed for oracle to be able to write backups (except for cio)
node2: NFS server
The mount seemed to be successfully done, but the transfer speed is terribly slow, about 3MB/sec.
Checked the network interfaces: both are JumboFrames enabled and MTU set to 9000, all interfaces link an 1000MB/s FullDuplex. Thested raw network transfer using ftp to move data from node1:dev/zero to node2:/dev/null and received a transfer speed of 115MB/sec. Tested local fs speed on node2 using dd to read from /dev/zero and the write it to the fs and succeeded to write 1GB in less than 9secs.
Checked client pages but there were no bottleneck (maxclient=10% and usage is ~3%)
Do you have any idea what to check yet to make it work in a correct speed?
