In the past i have had just about every customer i talk to wanting a 
nice gui for zone monitoring..


I just ran into this and it looks like the real deal.

Re: [zones-discuss] [Fwd: df -h in zone cluster]

[Joseph Balenzano]

I think this is the same issue as CR 6798104.  There is a workaround you 
can try which is documented in the report, which is use a df utility




Get a private copy of df from a Solaris 10 8/07 or 120011-14 and use the 
*private* copy when you need to check on the filesystem status.

*** DO NOT replace the df binary that comes with S10U6 with an older version ***

Hi,

software within zone cluster which does "df -h" to monitor disk space.

zdtgdbq01 is a ZFS pool used for Oracle database that has been added 
to this "zone cluster". Monitoring software looks at "size" column and 
sees "0K" and starts sending alerts.


Is there a solution for this? Or is that how it is going to be and 
they need to change the way they monitor it?


Customer thinks they haven't configured the resource group properly.

On SX:CE, it would be looking at the file system list with zonecfg for
inherit-pkg-dir.

In that case, it's harder to explain what you saw.  Is it possible
that 'catalogue4' was actually created as a clone of some other zone
on that system you're comparing against?

I doubt it's possible to do that in the OpenSolaris distribution, as
that's not based on System V packaging.  The tools are different
there.

Ermmm ... I don't think zones in OS is of the same type as zones in
S10.  They are of type ipkg, and in 10, they can be of type native,
branded, etc.  Zones in OS are independent of the global zone, they
pull their own packages using the package manager.  You may even say
that the concept of "sparse" and "whole" doesn't apply to zone in OS.

Sparse zones are not currently supported on opensolaris.

This is tracked as:
2550 Support for sparse root zones

- in solaris 10, just use "create" instead of "create -b" does a 
"sparse" zone

- in os2008.11, you have to add manually:

Don't do that.

The IPS pkg software does not currently support the concept
of a sparse zone.  The inherit-pkg-dir directive is
intimately tied to the packaging software.  Only the svr4
pkg software supports sparse zones right now.

[zones-discuss] zones in opensolaris (os200811) differs from zones in solaris 10?

[solarg]

hello all,
i'm wondering how to create a sparse zone in os2008.11:
- in solaris 10, just use "create" instead of "create -b" does a 
"sparse" zone

- in os2008.11, you have to add manually:

end
add inherit-pkg-dir
set dir=/platform
end
add inherit-pkg-dir
set dir=/sbin
end
add inherit-pkg-dir
set dir=/usr
end

but one thing i don't understand is the space devoted to the zones:

here for the "sparse" zone
rpool/export/toto  237M  15.8G37K  /export/toto
rpool/export/toto/ROOT 236M  15.8G18K  legacy

"REFER" is documented on the zfs(1M) man page.  It's the amount of
space accessible by the dataset and some or all of it may be shared
with another dataset.  If you're interested in the amount of disk
space used, then the "USED" column is what you want.

At a guess, the difference between these two machines is that
'catalogue4' was likely created as a sparse-root zone, while
'catalogue2' was created as a whole-root zone.  The clones of that
whole-root zone ('catalogue3' and 'test-drupal') use little disk
space, as most of it is 'referred' from 'catalogue2'.

This part of the output shows the relationships:

Gerard,

I can make a guess:  I suspect that space in your zones is being
consumed by data which is 'stuck' in zfs snapshots.  Can you do a 'zfs
list -t all'?  You might have an automatic snapshot service turned on,
or have manually made snapshots.


no for automatic snapshots i'm sure


Or you might be using zfs clones?  It would be nice to see the output of:


yes i'm using zfs clones
