zfs discuss - Jun 2009 - Turn off the time slider on some zpools

How to turn off the timeslider snapshots on certain file systems?

Using:
System/Administration/timeslider from default desktop menu item
System, I see a dialog to first enable[x] timeslider.  Then 3 columns
show a checkbox at lines with `mount point'' and `File System''
listed.

I had assumed that removing the check mark from certain file systems
would disable timeslider on the filesystem, so unchecked several and
then clicked OK.

Next time I look at System/Administration/Timeslider... I see all the
same boxes I unchecked are now back in the checked state.  That is, my
changes did not stick.

Should I expect that dialog to be able to turn of `Timeslider'' on
specific file systems?

I''m not prompted for a root password when working with the
`timeslider'' dialog either... and it seem that would be a protected
activity. 

Anyway... how can I turn off auto snapshots for specific filesystems?

Is the `Timeslider'' dialog just dis-functional... or is it a local
config problem?

The first steps fail here... At System/Administation/timeslider...
when I uncheck specific filesystems and click OK.  They don''t stay
unchecked and auto snaps continue.

Leaving the command line argument shown... which work great.
Thanks.

I wonder if the gui dialog is just dis-functional... or some local
config causing it to fail.

Hi Harry,

Are you attempting this change when logged in as yourself or
as root?

The top section of this procedure describes how to add yourself
to zfssnap role. Otherwise, if you are doing this step as a
non-root user, it probably won''t work.

Can''t speak for Harry, but time-slider -does- have a nasty habit. If I
change my zfs filesystems in a way that even ONE of those
com.sun:auto-snapshot:* is not used anymore time-slider goes nuts. For
this reason, and for this reason only I made sure -ALL- versions of
auto-snapshot are used SOME where ;-) That way they keep running and
time-slider is happy. I have not gone into it deeply, but somehow
services stopped running if not needed and you get those dependency
missing messages ;-/

Thank you, very handy stuff!

BTW - will zfs automatically delete snapshots, when I`ll go low on disk space?

my user is in role zfssnap.  And in role `root''

$ roles
postgres,root,zfssnap

I''m not sure how a user can access the gui tool without being logged
in as themselves.  Since the tool is on the dropdown menu System.

Do you mean root has to log into X?

But anyway.. the command lines shown on that page are much handier
anyway.  I just wondered if the Gui tool was working as expected.

Hi Mykola,

Yes, if you are speaking of the automatic TimeSlider snapshots,
the snapshots are rotated. I think the threshold is 80% full
disk space.

Cheers,

Cindy
