zfs discuss - Nov 2005 - auto_home not working after switching /export/home to ZFS

I installed OpenSolaris build 27a.  Then I unmounted /export/home and used the
zpool to create a new ZFS pool using the /export/home partition.  I then created
a new filesystem pool/home and set the mountpoint to /export/home.  When I try
and login I get :

Could not chdir to home directory /home/sam: No such file or directory

The /home directory is still in the auto_home and auto_master files.  Is there a
persmissions problem or something?

What does:

% ls -ld /export /export/home /export/home/sam

output?

Where is the association between /home and /export/home ?  I''m very
familiar with Mac OS X and Redhat Linux, but not so much with Solaris.

/etc/auto_home is the main source of configuration;  see automount(1M).

I think if you put:

	* localhost:/export/home/&

into /etc/auto_home, and ran "automount -v", it would do the right
thing.

That didn''t do anything. No mounts/unmounts.  Perhaps there is some
underlying assumption here that I don''t understand.  Someone here said
something about needing NIS+ but I chose DNS on install for instance.

Also, useradd doesn''t appear to create a directory anywhere.  There
must be something here that I''ve misconfigured.

More info:

auto_master:

+auto_master
/net            -hosts          -nosuid,nobrowse
/home           auto_home       -nobrowse

auto_home:

+auto_home
* localhost:/export/home/&

exportfs -v:

share -F nfs
-               /opt   rw   ""  
-               /export/home   rw   ""  

passwd:
sam:x:100:1::/home/sam:/bin/bash

Anything else you might need to look at?

Hmmm. I found this bug:

http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6244467

How am I supposed to create new users?

I''m no expert in ZFS but I''ve played with the automounter a
bit.

There''s a nice undocumented debugging feature on autofs which allows
you
to see what the automounter is trying to do. It might help you see why 
it''s not mounted.

might help
