zfs discuss - Dec 2009 - Remote synchronization of two pools: synchronizing ZFS properties

Hi All,

My question is related to: 6839260 want zfs send with properties.

I''m running "zfs send | mbuffer | network | mbuffer | zfs
recv" nightly between two arrays (2008.11), but my backup script does not
do recursive send/recv - it walks through all datasets, sends the increments one
by one and re-creates any newly added datasets.

I''m wondering if any of you are using a similar solution and ran into
the same issue. Non-recursive send/recv does not send (all) properties of a
dataset - for example quota and compression. What I''m thinking of is
just defining properties I want to synchronize, and doing them one by one like
this:

for dataset in $datasets; do
for prop in $props; do

A=zfs get -Ho value $prop $dataset
B=ssh slave zfs get -Ho value $prop $dataset
if [  B!=A ]; then  ssh slave zfs set $prop=$A $dataset; fi

done
done


The example above is of course simplified, as we also have inherited properties
- but Is there any smarter / proper way of synchronizing properties between two
pools (on 2008.11)? Basically, the properties I care about are: quota,
compression, share*

Many thanks,
owczi
