Hi guys,
Using FreeNAS-9.2.1.3-RELEASE-x64
New to ZFS.
I've been reading this:
http://doc.freenas.org/index.php/Volumes#Creating_ZFS_Datasets
and this:
http://doc.freenas.org/index.php/Volumes#Creating_a_zvol
and a few other stuff
I'm still unsure why you would use ZVOLs...
Also I don't understand why you CAN created ZVOL nested inside a DATASET.
But why you can not create a DATASET nested inside a ZVOL.
So first... I understand how to manage ZVOLS and DATASETS but what are their usages?
I think DATASETS are quite simple: folders.
And ZVOLS have the feature of allowing you to create a block and reserve space on the volume.
I don't need to use it as a iSCSI device extent, or use a different file system.
I just want to take advantage of the reserved space (quota).
But then you can't manage this ZVOL using DATASETS or else...
So I'm wondering if I should be using ZVOLS at all.
What I'm trying to accomplish :
4 X 4TB drives in RAID 10 (stripped mirrors) = 8TB
I would like to keep 4TB for virtualization and 4TB for shares.
Dataset won't let me set quotas.
That's why I turned to ZVOLS.
What do you think?
