How to connect to iscsi resource in Fedora (or any other distro)

Installation

Just in case, install initiator (it comes preinstalled)

$ sudo dnf install -y iscsi-initiator-utils

(Optional) Add it on the server:

If your target requires to add initiator name get it with:

(On the client)

$ sudo cat /etc/iscsi/initiatorname.iscsi
InitiatorName=iqn.1994-05.com.redhat:af54e632d6e

And add it to the target.

(On the server)
$ nano /etc/tgt/conf.d/target01.conf

<target iqn.2019-04.baj.home:dlp.target01>
    # provided devicce as a iSCSI target
    backing-store /media/hdd1/iscsi/lun0.img
    # iSCSI Initiator's IQN you allow to connect to this Target
    InitiatorName=iqn.1994-05.com.redhat:af54e632d6e
</target>

Restart service

(On the server)
$ sudo service tgt restart

Find the target

$ sudo iscsiadm -m discovery -t st -p 192.168.0.110
192.168.0.110:3260,1 iqn.2019-04.baj.home:dlp.target01

Connect to the target

$ sudo iscsiadm -m node \
        --targetname iqn.2019-04.baj.home:dlp.target01 \
        -p 192.168.0.110:3260 -l

Logging in to [iface: default, target: iqn.2019-04.baj.home:dlp.target01, portal: 192.168.0.110,3260] (multiple)
Login to [iface: default, target: iqn.2019-04.baj.home:dlp.target01, portal: 192.168.0.110,3260] successful.

Check partitions:

$ lsblk

Automount it with fstab

Instead of using partition name, we will map it with UUID

Find the UUID with the partition name

$ lsblk -f | grep sde
sde                                                                       ├─sde1
└─sde2         ntfs        STEAM     C2F4FFA0F4FF953F --> UUID

Make folder to mount

$ sudo mkdir /mnt/iscsi

Edit /etc/fstab

$ sudo nano /etc/fstab

Add this line to the bottom:

UUID=C2F4FFA0F4FF953F /mnt/iscsi  ntfs  _netdev,uid=1000,gid=100 0  0

Reboot and it should be mounted!

UPDATE 2020

On mint 19.3, iscsid service refused to start after some update. fixed it by changing the command to start the service.

sudo diff /etc/iscsi/iscsid.conf /etc/iscsi/iscsid.conf.dpkg-old

21,22c21
< #iscsid.startup = /bin/systemctl start iscsid.socket
< iscsid.startup = service iscsid start
---
> iscsid.startup = /bin/systemctl start iscsid.socket
