zfs discuss - Mar 2006 - disappearing mount - expected behavior?

Hi,

the following occured on opensol-20060228:

My home directory is on a local disk (i.e. /export/storedge/home/thomas). It is
mounted with autofs.

I created a zfs:
zfs create zfs/thomas

Then I set the mountpoint as a subdirectory of my home:

zfs set mountpoint=/home/thomas/zfs zfs/thomas

Everything looks fine and I fill this directory with a bunch of files. But after
rebooting /home/thomas/zfs is empty.
Resetting the mountpoint to its standard directory made the content reappear.

OK, I think I am a little bit nasty setting a zfs mount point to a subdirectory
of an autofs directory.
So I am wondering now, is this the expected behavior?

Hi.

Let me guess - when you reboot first zfs fs is being mounted then autofs.
I guess that''s your problem.

If you home is on local disk anyway then maybe turn off autofs (at all on at
least for /home).

What happens is that /home/thomas/zfs gets mounted and then the
automounter starts.  (Or /home/thomas is found missing and then
the zfs mount is not completed)

Probably requires legacy mount point.

I''m experiencing this same behavior (ZFS NFS mounts don''t show
after reboot) with b50 and was hoping someone could outline a little clearer for
those of us not as intimately familiar with Solaris innards.

I can simply issue one ''zfs share zfsdata/[user1]'' command and
all my other ZFS-issued NFS mount points reappear.

My /etc/auto_home is:
[user1] 127.0.0.1:/export/home/[user1]
[user2] 127.0.0.1:/export/home/[user2]
   etc...

All SMF services are running normally - nothing in maintenance or failed to run.

I dot NOT have any entries in my /etc/vfstab pertaining to the /export/home
directories, all of which are on a ZFS pool.

Should I simply comment out the /etc/auto_home entries?  Or, should I create an
entry in /etc/vfstab?  If so, is one to /export/home sufficient or must one be
done for each user [each user has his/her own ZFS pool]?

Sorry, I''m just not sure what a "legacy mount point" is.

Many thanks in advance!
