Since battle.net does not allow installing games on NFS, I’ve decided to setup iSCSI target on Fedora.
- Install scsi-target-utils and create a disk image:
[root@fedora ~]# dnf install scsi-target-utils
[root@fedora ~]# mkdir /share/iscsi-disks
[root@fedora ~]# cd /share/iscsi-disks/
[root@fedora iscsi-disks]# dd if=/dev/zero of=disk01.img count=0 bs=1 seek=350G
[root@fedora iscsi-disks]# ls -alF
total 32822716
drwxr-xr-x. 1 root flatwhite 20 Jun 13 10:23 ./
drwxrwxr-x. 1 root flatwhite 592 Jun 14 11:35 ../
-rw-r--r--. 1 root flatwhite 375809638400 Jun 14 13:36 disk01.img
[root@fedora iscsi-disks]# - Add tgt configuration file:
[root@fedora iscsi-disks]# vim /etc/tgt/conf.d/target01.conf
<target iqn.2025-03.coffee.nicewarm:fedora.target01>
# provided device as a iSCSI target
backing-store /share/iscsi-disks/disk01.img
# iSCSI Initiator's IQN you allow to connect
initiator-name iqn.2025-03.coffee.nicewarm:gentoo16.initiator
# authentication info ( set anyone you like for "username", "password" )
</target> - Update SELinux and firewall rules:
[root@fedora iscsi-disks]# chcon -R -t tgtd_var_lib_t /share/iscsi_disks
[root@fedora iscsi-disks]# semanage fcontext -a -t tgtd_var_lib_t "/share/iscsi_disks(/.*)?"
[root@fedora iscsi-disks]# ls -alFZ
total 39776832
drwxr-xr-x. 1 root flatwhite system_u:object_r:tgtd_var_lib_t:s0 20 Jun 13 10:23 ./
drwxrwxr-x. 1 root flatwhite system_u:object_r:default_t:s0 592 Jun 14 11:35 ../
-rw-r--r--. 1 root flatwhite unconfined_u:object_r:tgtd_var_lib_t:s0 375809638400 Jun 14 13:45 disk01.img
[root@fedora iscsi-disks]# firewall-cmd --add-service=iscsi-target
success
[root@fedora iscsi-disks]# firewall-cmd --add-service=iscsi-target --permenent
success- Start tgtd service and verify
[root@fedora iscsi-disks]# systemctl enable --now tgtd
