I run RELENG_7 on my home machine, using ZFS with a zpool of two disks (basically the equiv. of a RAID 0 array). The storage pool is about 1TB, and mainly contains ISO images. The network interface on the boxes are gigE, and I copy data quite regularly. I have absolutely no ZFS- related tuning parameters set in my loader.conf or sysctl; I'm using all the stock out-of-the-box settings. I run Samba as well, which has shares for numerous directories on that ZFS pool. I haven't run into any problems that appear to be ZFS or Samba-related. > On occasion I will find that directory information sometimes goes funky > when coming out on the Windows XP side.

I have seen something similar happen, and I believe it to be a Windows "problem" (if you can call it that) more so than a SMB/CIFS or ZFS problem: Say you have /foo/bar as a shared SMB resource via Samba on a UNIX box. If on the Windows machine you browse to that folder (in Windows Explorer), then on the UNIX box rm -fr /foo/bar/someotherdir, you will not see the someotherdir directory disappear in Explorer until you actually click Refresh. Otherwise, I haven't ever seen what you've reported. I'm not sure why you think it's related to ZFS though; the behaviour you describe should happen on any underlying filesystem or LVM equivalent. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
