Jochen,
The 89 GB is what is currently being reserved. The reason it is a lot
less than 330 GB is because your actual exchange database is probably
only about 89 GB. NetApp is sparse in nature, meaning even if you create
a 330 GB lun it does not actually go and create a file 330 GB large.

Subject: Snap Manger / Space reserve
Hi everybody,
i am new to the whole netapp topic and right now i'm a little bit
confused. Currently we run a FAS920 with a LUN for our exchange
database. We use snapdrive and snapmanager to take snapshots of this
system and here is my problem. As i was told LUN's do not need a "Snap
reserve" in the traditional way so i changed this setting to 0%.
What i am wondering now is the output of df -hr
total used avail
reserved
/vol/exchdata 700GB 428GB 271GB 89GB
The Lun is currently at 330 GB so i expected the reserved space to be
330 GB too, because i learned with LUN's it is the default and recommend
setting to have it like that.
Can anybody help? Where does this 89 GB come from and is there a command
to see how much space is currently reserved for this LUN?
Rgds and thanks in advance
Jochen
