My freenas 7 worked reasonably well. When I did a fresh install of freenas 8 it became impossible to copy or move files from one ZFS volume to another.

E.g.,

/tank/ /tank/content/ /tank/archive/ /tank/video/

I can copy/move a 400 Mb file from any of the above volumes to either of my Macs, or to any of my Windows machines. I can also copy / move the file back to any of the above volumes. In other words the network and other factors seem to be working flawlessly. The speed is 85% or so of the 1 Gb LAN.

The problem starts if I try to use Finder (or Explorer in Win) to drag a file from, say, /tank/video/ to /tank/archive/. This worked fine under freenas 7. Under freenas 8 it does the following:

  • dialog appears in both OSX and Win: preparing to move file
  • dialog stays there for a long time
  • eventually it usually times out
  • sometimes the file is partially copied
  • while this is happening the whole freenas server seems to grind to a halt -- music playing from iTunes stops, etc. etc. This does not happen when copying to/from Mac desktop
  • permissions not the issue -- can copy exact same file from /tank/video to mac desktop, then from mac desktop to /tank/archive

Any help would be much appreciated!

How about if you just do a cp on the FreeNAS system's command line? – Shane Madden Feb 9 at 2:32
Good point. Can't believe I didn't try that earlier. So anyhow the cp works fine. This is all very strange... the problem only exists when copy/move from a client machine, and only from one ZFS vol to another. Still stymied! – Steve Macdonald Feb 9 at 19:46
Hmm... starting to think this may be a very odd network issue after all. For totally unrelated reasons I disabled my Apple Time Capsule today. All of a sudden the problem appears to be gone. The Time Capsule was behaving erratically after a firmware bump, and may have been defective before that. How it could possibly cause this problem is way beyond me. I'll update here if that ends up being the culprit. – Steve Macdonald Feb 9 at 19:51
Interesting.. I'm not familiar enough with the time capsule behavior to make a good guess at why it'd be related, but I'm definitely curious if that ends up solving it. – Shane Madden Feb 9 at 21:39
