Re: [zfs-discuss] The same data on two pools shows different on disk size?

2011-12-06 Thread Ryan Wehler 
I should also mention there are no snapshots on either the source or 
destination datasets.

zfs list -t snapshot  | grep GCMS
root@calculon:/volumes/tank#

[zfs-discuss] The same data on two pools shows different on disk size?

Is this just due to the size/config of the pools? The data is exactly the same! 
I just copied FROM raidpool (smaller size count) to tank. All the settings on 
each pool are default with compression being the exception  The only thing I 
can think affecting this is the pool size/layout:

zpool status raidpool
