Now that my server is basically up and running for a while it’s time to get the neat stuff running 🙂 .
A to-do item on my list has always been enabling jumbo frames and LACP on my Opensolaris installation. So, let’s get this kicking!
Jumbo frames use a MTU of 9000 instead of 1500. Since I’ve aggregated nge0 and nge1 to aggr1 I can simply set the MTU of the aggr and the corresponding values will automatically be set on nge0 and nge1 (even if you don’t see them 😉 ):
ifconfig aggr1 unplumb dladm set-linkprop -p mtu=9000 aggr1 ifconfig aggr1 plumb
Sweet stuff! Don’t forget to re-configure the address, netmask and gateway for the link. Now I want to enable LACP so I can make use of the combined throughput of the NICs:
dladm modify-aggr -L passive 1
Let’s check whether everything’s up and running as intended:
tsukasa@filesrv:/$ ifconfig aggr1 aggr1: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 9000 index 2 inet 192.168.X.X netmask ffffff00 broadcast 192.168.X.X
tsukasa@filesrv:/$ dladm show-aggr 1 LINK POLICY ADDRPOLICY LACPACTIVITY LACPTIMER FLAGS aggr1 L4 auto passive short -----
And indeed, everything went smooth.
Now, even with this boost in performance watching HD video over the network sometimes stuttered with many concurrent connections/operations going up- and downstream at the same time. Also, the Opensolaris 2009.06’s CIFS service has the unpleasant habit of dying and refusing to come up again until I reboot, so I went the easy way and simply enabled NFS for this ZFS system (can we call this a system? Mount? I don’t know…):
zfs set sharenfs=on filesrv/video
I didn’t have to do anything else or specify explicit rw options since I already mapped all the stuff before. Now, the only thing left to do:
mount filesrv:/filesrv/video /home/tsukasa/video -t nfs -o defaults,users,noauto,rsize=8192,wsize=8192,timeo=14,intr
And guess what, no more problems 🙂 .
