At least it means I haven't completely lost it yet! > > > We have had trouble in the past with large numbers of shares, and > we're not done with the work to address it yet.

One time I did see it timeout after an hour - that particular time I was creating a bunch of ZFS filesystems at the same time, and it was going /really/ slowly (one FS about every 30 seconds). I'm guessing some sort of global zfs lock was probably holding up the start script, and it timed out... But either way, I'm not seeing that now. > > > I would try to get things stable with just one share in dfstab; > you do have to have at least one for the server to not disable > itself.

It starts up, complains that there's no shares, then shuts down. Interestingly enough, it rewrote my dfstab to: share -F nfs -o sec=sys,ro /tmp so someone somewhere did see the line and rewrote it. I also tried using a share command directly in my conversation with Tom earlier - same symptoms. Thanks for the help! Hopefully we can get this going soon, I've got a very finicky NFS server which really needs to be retired soon and replaced by this guy ;-) Steven
