ZFS as Directory?

[spearox]

Hello!

I want to use ZFS but i want to store iso backups snapshots ect on this volume too so if i create a zfs volume and i mount as a directory i can use this functions?
It is right way to do this? Or i think something wrong?

 

[Nemesiz]

Yes you can

 

[spearox]

Thats fine. And this is right way? Or i do something wrong if i choose this way?

 

[Nemesiz]

It will work. I use this way for templates (iso, cache) for VM (openvz, kvm)

But with ZFS?
And if i don't have any ssd for cache good to use ZFS or better to use the raid controller card with writeback cache + bbu?

You dont need SSD for cache - you need RAM for cache. SSD is more for ZIL (write cache (sync write)). ZFS is COW (copy-on-write) so you dont corrupt your data.

If you want data protection and performance for your requirements you will have to invest to it. First try it and upgrade as needed.
