PBS API - I can't create ZFS pool

[HarusKG]

Hello everyone.

I'm trying to automate the setup of my PBS using Ansible and ran into an issue where I can't create a ZFS pool via the API.
I decided to try creating it using curl for testing. My script looks like this:

curl -X POST \
  --insecure --cookie "$(<cookie)" --header "$(<csrftoken)" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "pool",
    "devices": ["/dev/sdb", "/dev/sdc"],
    "raidlevel": "mirror",
    "compression": "lz4",
    "ashift": 12
  }' \
  "https://$APINODE:8007/api2/json/nodes/localhost/disks/zfs"

But it gives me this error:
parameter verification failed - 'devices': Expected string value.

I've tried different options but haven't succeeded. Where did I go wrong?

Hi,

devices must be a comma-separated value, see also the documentation at https://pbs.proxmox.com/docs/api-viewer/index.html#/nodes/{node}/disks/zfs (need to click on POST at the top, first).

"https://$APINODE:8007/api2/json/nodes/localhost/disks/zfs"

Also, while using localhost for the node name does work, it's rather discouraged and not guaranteed to work as expected.

Can you show me using my example?
I tested multiple approaches, including

    "devices": "/dev/sdb",
    "raidlevel": "single"

None of this worked

Spoiler: Full script

#!/bin/bash
export APINODE=pbs
export TARGETNODE=pbs

curl -X POST \
--insecure --cookie "$(<cookie)" --header "$(<csrftoken)" \
-H "Content-Type: application/json" \
-d '{
"name": "pool",
"devices": "/dev/sdb",
"raidlevel": "single",
"compression": "lz4",
"ashift": 12
}' \
"https://$APINODE:8007/api2/json/nodes/$TARGETNODE/disks/zfs"

I found the issue.
The correct line should be:
"devices": "sdb,sdc"
