zfs discuss - Mar 2009 - cannot mount ''/export'' directory is not empty

Hello,

I am desperate. Today I realized that my OS 108 doesn''t want to boot.
I have no idea what I screwed up. I upgraded on 108 last week without
any problems.
Here is where I''m stuck:

Reading ZFS config: done.
Mounting ZFS filesystems: (1/17) cannot mount ''/export'':
directory is
not empty (17/17)

$ svcs -x
svc:/system/filesystem/local:default (local file system mounts)
State: maintenance since ...
Impact: 45 dependent services are not running.

svc:/network/rpc/smserver:default (removable media management)
State: uninitialized since...
Impact: 2 dependent services are not running.

$ zfs mount

rpool/ROOT/opensolaris-2            /
rpool/export/home                        /export/home/wewek
rpool                                             /rpool
tank                                              /tank
tank/projects                                /tank/projects
.
.
.
.

$ pfexec zfs mount -a
cannot mount ''/export'': directory is not empty

I can mount rpool/export by -O option but I''ll lost my home directory
and Gnome can''t come up.
$ pfexec zfs mount -O rpool/export
$ svcadm clear filesystem/local:default
Mounting ZFS filesystems: (17/17)

GDM login comes up, after log in:

"Your home directory is listed as: ''/export/home/wewek''
but it doesn''t
appear to exist. Do you want to log in with the / (root) directory as
your home directory? It''s unlikely anything will work unless you use a
failsafe session."

Can you help me please? I don''t want to loose all my configurations.

Thank you!

It seems like you have some stuff in /export  which does not belong to
the filesystem that should be mounted in /export

That is, you have /export/somefileordirectory  that belongs to the /
filesystem.. Try this:

pfexec mv /export /oldexport
pfexec mkdir /export
pfexec zfs mount -a

Hi Tomas,

thanks for the answer.
Unfortunately, it didn''t help much.
However I can mount all file systems, but system is broken - desktop
wont come up.

"Could not update ICEauthority file /.ICEauthority
There is a problem with the configuration serve.
(/usr/lib/gconf-check-2-exited with status 256)"

Then I can see wallpaper and cursor. That''s it, nothing more.

There''s a bug with mounting hierarchical mounts (i.e. trying to mount
/export/home before /export or such), you might be hitting that
(unfortunately the bugid escapes me at the moment).
