Using a single drive for jails.

[Tankton]

Here is my basic setup.
Intel Xeon 8 Core
8gb Ram
3x2 3TB drives set up as one pool. Which gives me 9TB storage.
I would like to add a 500gb drive just for jails. Will I have to add 2 500gb drives as
a raid or can I do it with just one drive?

You can just do a single drive. It's common for people to use a ssd for their jail pool.

Thank you for the quick reply. I really didn't want to waste a drive if I didn't have to.
I will add that to my layout.

I personally run a striped pool with 2 SSDs to get more space and performance and I run a local replication task to save all my jail stuff to my HDD pool for safety in case one of the SSDs fail.

Is there some reason you don't want your jails on your main pool?

Some apps like Plex have large databases, so in addition to the jails themselves, I have an "apps" dataset per app to store things like databases for fast performance... I count that all as my jails. I prefer the performance of SSD for the databases and I feel like the performance of the jails is a little better (although I agree it's really not mandatory to have it like that).

Meh, I've got 12 jails running on my main pool (including Plex) and I don't notice any performance hit because of it. I've just always questioned why people insist on having jails on a separate pool/SSD's unless there is a specific need for it. You've built a pool with redundancy to protect against data loss why not use that for your jails as well?

Just my $.02............

8gb Ram

8Gb is the deployment minimum. You might want to consider more RAM if you're planning on running jails.

Is your plex DB 300GB?

 

[NugentS]

Your plex metadata etc is 300GB?
My Plex Jail is 440MiB and the Plex_data is 15GiB

Bloody hell

85

At the moment that is what I'm running for setup and initial testing. I will be replacing that with 32GB Server Ram.
The motherboard is complaining about this ram anyways. And I will only be running some backup software in the jails, nothing
heavy. This is a storage and file server first.
