zfs discuss - Jul 2011 - Each user has his own zfs filesystem??

I dont get it. I created users with 
System -> Administration -> Users and Groups
meny.

I thought every user will get his own ZFS filesystem? But when I do
# zfs list
I can not see a zfs listing for each user. I only see this:
rpool/export                              60,4G   131G    32K  /export
rpool/export/home                         60,4G   131G  60,4G  /export/home
rpool/export/home/michaelroot                 760K   131G   760K 
/export/home/michaelroot

I have at least three users in my system. I thought they would be listed when I
do "zfs list"?

Maybe you don''t have their home directories created while adding
them...?

So, when I created users with the GUI
System -> Administration -> Users and Groups
meny, it did not automatically create a zfs filesystem?? I must do that
manually? Or are the users on a separate user filesystem?

I tried to move a large file from user to /rpool, but the system copied instead
of moving. This is an indication of user having a separate filesystem. But the
filesystem is not listed in "zfs list".

Orvar,

What does it say in the new users'' entries in /etc/passwd, and what do 
you see if you ''ls -l /export/home''? Perhaps you only have
directories
underneath /export/home instead of new ZFS datasets.

So this is strange. By default the GUI does not create zfs filesystems? I must
do that manually?


Are there any way I can tell which filesystem/partition a directory belongs to?

I would have found it strange if it did.  What other OS are you using 
that creates a separate filesystem per user?

I am not near a Linux system now to try this, but, for what its worth, 
in Solaris 11, doing a df <dirname> will show the file system and 
mountpoint.

Oops! Bad email filtering - for some reason I had this message in the

That is correct. 

Those of us working in ZFS land recommend one file system per user, but the 
software has not yet caught up to that model. The wheels are turning though.

When I get back to office, I will send out some steps that might help during
this transition.

Thanks,

Cindy

Ah, ok. That explains it all. Thanx. 

And yes, "df" did the trick.

So, if I want each user to have his own zfs filesystem, I just create the
filesystem, and then copy everything from /export/home, and then I fire up the
GUI and point to the new zfs filesystem? That is all? I dont have to edit
/etc/passwd and such files?

Or should I just delete the user and recreate the user?

A question: if a user share filesystems, how can "Time Slider" work? I
heard it snapshots the user zfs filesystem. If a user share filesystems, does
this mean that TimeSlider snapshots the entire system disk?
