Do you also have a /tank/fs1? I.e., the shares down below don't match the paths. This shouldn't be the problem you are seeing...

Seems I've got a problem ^^ But what? Aren't the filesystem handling the sharing? Yes, they should be. I'm adding zfs-discuss to see what further triaging will help.

I assmume the prefix "-t nfs" equls v3? I get: mount.nfs: access denied by server while mounting srv:/bitbox You don't need "-t nfs", just dropping the -t option will work. But the fact that we don't see a share means we do not expect to get access here. I don't get it! Also, where are the config files, such as the /etc/export? If this were non-zfs, you'd want to look in /etc/dfs. But since this is zfs, the share (i.e., export) is in the sharenfs property of the filesystem. Thanks!

[zfs-discuss] Re: Re: ZFS with raidz
We've got some work going on in the NFS group to alleviate this problem. Doug McCallum has introduced the sharemgr (see http://blogs.sun.com/dougm) and I'm about to putback the In-Kernel Sharetab bits (look in http://blogs.sun.com/tdh - especially http://blogs.sun.com/tdh/entry/in_kernel_sharetab_have_a). Doug has been doing some performance optimization to the sharemgr to allow faster boot up in loading, specifically for ZFS - see for example http://bugs.opensolaris.org/view_bug.do?bug_id=6491973. It is funny, he just told me a couple of hours ago that he was doing 15k entries. I know he has significantly reduced the times for 3k and 5k filesystems. We are still working on the 15k entries. We are wanting to combine his changes with my changes to see if we can get the 15k time down. With my changes, we remove going to disk for the sharetab and locking the file. As you can see, this is a very hot spot for us right now. We really want these times down. Also, for the interested, I gave a presentation at Connectathon last year which highlights some of the issues here: Scaling NFS Services (http://www.connectathon.org/talks06/haynes.pdf). I also presented an overview of Doug's and my projects at the latest Connectathon: The Management of Shares (http://www.connectathon.org/talks07/ScaleShares.pdf).

[zfs-discuss] Article on impact of NFS share management to ZFS boot times
We just had an article published on SDN about how different changes to the ways shares are handled has an impact to the boot up time for large numbers of ZFS filesystems. For me, one of the neat things about it was it being a topic at several points on OpenSolaris discussion boards. You can view the article on 'The Management of NFS Performance With Solaris ZFS' over at http://developers.sun.com/solaris/articles/nfs_zfs.html.
