We have seen this behavior, but it appears to be entirely related to the hardware having the "Intel IPMI" stuff swallow up the NFS traffic on port 623 directly by the network hardware and never getting. http://blogs.sun.com/shepler/entry/port_623_or_the_mount Unfortunately, this nfs hangs acr

So it is expected behavior on my Nexenta alpha 7 server for Sun's nfsd to stop responding after 2 hours of running a bittorrent client over nfs4 from a linux client, causing zfs snapshots to hang and requiring a hard reboot to get the world back in order? Thomas There is no NFS over ZFS issue (

After researching this further, I found that there are some known performance issues with NFS + ZFS. I tried transferring files via SMB, and got write speeds on average of 25MB/s. So I will have my UNIX systems use SMB to write files to my Solaris server. This seems weird, but its fast. I'm sure

I have a very similar setup on opensolaris b62 - 5 disks on raidz on one onboard sata port and four 3112-based ports. I have noticed that although this card seems like a nice cheap one, it is only two channels, so therein lies a huge performance decrease. I have thought about getting another car
