ZFS and Storage Question

[SuperMiguel]

So i created a raidz zfs with 4 drives, and created few pools, now i want to use one of my pools for data like for a file/media server, how should i add it to proxmox? ass a ZFS or as a directory?? I may need to access folder of this pool from different vms? I see the shared checkbox when adding it as a directory but not when doing zfs..

I suppose you created one pool consisting of your 4 drives, right? Could you please post the output of

zpool status -v

(and please use CODE tags for better readability)

So i have 2 pools
rpool my install pool (3 ssd in raid 1) and data which is 4 1tb drives

zpool status -v
  pool: data
 state: ONLINE
  scan: none requested
config:

        NAME        STATE     READ WRITE CKSUM
        data        ONLINE       0     0     0
          raidz1-0  ONLINE       0     0     0

If you use containers you an use mount points which i find are the best to work with, alternatively I would recommend setting up NFS/samba on the pool and mounting it via that way in your vms.

Yup im using containers, if i add the storage to my datacenter as directory i can mount it to multiple containers if i add it as ZFS only one right?

What i personally do for say media is

zfs create data/media

To create a media dataset and then mount it to the drives by editing their config via terminal

For instance if the node ID was 100 you would want to edit /etc/pve/lxc/100.conf and add this line

mp0: /data/media,mp=/mnt/media

Note that the /mnt/media folder needs to exist before adding this and that there cannot be any spaces before and after the comma otherwise it wont work. Its very picky about it.

I have no idea.

So after i create a zfs pool, created data/data, so the question is whats the best way to mount this inside promox? i have two options mount it as ZFS or mount it as a directory, any speed difference between the two? any considerations or issues between the two? also i want to be able to access the same share from different containers, like i will have 1 container running a file server, and another one maybe running a media server so there will be some files used by both. If i mount it as a directory there is a checkbox that says shared does this do what i want?

 

[12jdlovins]

when you do zfs create data/data it should automatically mount it, at least in my experience.

As for the checkbox i dont know where that is.
