Need help to manage my pool/disk [EN/FR]

[Eysiox]

Hello, my DIY server works with True Nas-12.0-U1.1

I have a problem: I currently have 2 pools:

The first one consists of:
- SSD 240 gb
-HDD 300 gb

The second pool of:
-HDD 230 gb

On the first pool there are the plugins (mineos, nextcloud, plex)
The second is used for vm.

I'd like to make it several more pools to separate plugins:

one pool for nextcloud one for mineos and the last one for plex to separate all the plugins on separate disks (HDD/SSD).
Is this possible?

On my side I tried but all the plugins in each pool don't start automatically, only the pool selected in "plugin" starts by itself.

Bonjour, mon serveur DIY marche avec True Nas-12.0-U1.1

Je rencontre un problème: j'ai actuellement 2 piscines:

La première constituée de:
- SSD 240 gb
-HDD 300 gb

La seconde piscine de:
-HDD 230 gb

Sur la première piscine il y a les plugins (mineos, nextcloud, plex)
La seconde est utilisée pour les vm.

J'aimerais faire en sorte qu'il est plusieurs pools en plus pour séparer les plugins:

une pool pour nextcloud une pour mineos et la dernière pour plex pour séparer tous les plugins sur des disques (HDD/SSD) séparés.
Cela est t'il possible ?

De mon coté j'ai essayé mais tous les plugins de chaque pool ne démarrent pas automatiquement seulement le pool sélectionné dans "plugin" s démarre tous seuls

Unfortunately, this isn't possible. iocage, which manages jails/plugins, can only be active on a single pool.

All right, thank you. There is no possible alternative to separate the disks as much as possible. Or to separate plugins on the same pool with different databases for example ?

You can of course use the "mountpoints" feature of jails to e.g. mount a dataset in your HDD pool into e.g. /var/nextcloud/data in your Nextcloud jail and use that as the data store directory while still running the jail itself from your SSD pool.

I use that for Nextcloud and Mineos. Jails on SSD, large data on HDD.

All right, thanks. I'll keep you posted.

I looked for ways to do what you told me but I couldn't find them. Do you have an explanatory video/tutorial?I looked for ways to do what you told me but I couldn't find them. Do you have an explanatory video/tutorial?

Click the < at the right of the jail to expand it. There will be a button for Mounts. You can choose various datasets outside the jail, and map them to paths inside the jail.

My gut feeling is that we should take a step back and ask why @Eysiox wants to do this. We are at a fairly technical detail level, whereas the setup description implies to me that there is a lack of general knowledge about ZFS and TrueNAS. The latter is not a bad thing , but I think some "general" guidance may be more helpful at the end of the day.

My gut feeling is that we should take a step back and ask why @Eysiox wants to do this.

I think it is perfectly reasonable to want to run your jails from SSD while keeping large chunks of stationary data on your HDD pool. Like in a typical Nextcloud installation.

So these are the datasets on my HDD pool:


And this is the "mountpoints" setting for my Nextcloud jail:


So the dataset /mnt/hdd/data/nextcloud - which lives on the "hdd" pool - is mounted into the jail living on the "ssd" pool at /mnt/ssd/iocage/jails/cloud/root/var/nextcloud - which happens to be /var/nextcloud when viewed from inside the jail.

Just make sure ownership of the dataset is correct for your application. In the case of Nextcloud that is easy. Nextcloud runs as user "www" inside the jail and that user exists outside of the jail in TrueNAS, too, with the same UID/GID. So no additional magic needed, just change the user and group of the dataset using the "edit permissions" menu item:


That's all ... HTH,
Patrick

Perfect everything works thanks to you
