Hi everyone,
Very new on the proxmox project, I give it a try to setup a homelab.

I am trying to setup a connection to an ISCI LUN on a synology NAS on the same network. The discovery is OK (I can list the different target) but when I try to validate the connection, I have a timeout message. If I refresh the page, the iscsi datastore is available but I do not think it is a normal behavior.

If I delete the datastore, it does not correctly delete the connection. I need to delete it manually with iscsiadm command.

Here is the log when I try to add the datastore.

Code:
root@promox:/var/log# cat syslog | grep iscsi
...

Do I miss something?

I too am very new to Proxmox (coming from Hyper-V) and also was setting up iSCSI from my proxmox box to Synology.

Set up the LUN on the Synology system and set up (non-mutual) CHAP. Modified /etc/iscsi/iscsid.conf on proxmox with CHAP details.

Code:

The only way I've been able to get it to work so far is to disable CHAP on my Synology iSCSI target.
