Since battle.net does not allow installing games on NFS, I’ve decided to setup iSCSI target on Fedora.<\/p>\n\n\n\n

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

            \n
          1. Install and configure open-iscsi:<\/li>\n<\/ol>\n\n\n\n
