 Servcie should wait for the window manager to be up (gdm for Gnome)

iSCSI requires network to be up iSCSI has to authenticat first LVM on iSCSI and USB devices has to wait for the services to be up LVM on local devices (PATA, SATA, ThunderBolt) mount at boot time Solution was to mark all iSCSI and USB filesytems to "noauto" and write a new system script to mount the filesystems

iSCSI Terminology Server (target) side Install iSCSI software $ sudo  dnf -y install targetcli Create IQN with  iscsi-iname (see the example above) Create backstore data areas Quite simple example for most of systems: $ sudo targetcli /backstores/block create disk0 /dev/sdb $ sudo targetcli /backstores/block create disk1 /dev/sdc $ sudo targetcli /backstores/block create disk2 /dev/sdd Note: For entire physical disks I recommend using the WWN instead of disk device or partition id. This ensures that the disk reference will not change during system restarts (quite common when using USB disks). Another option is to use the disk UUID. However, a new partition map is created (using fdisk), the UUID will change. Also, if you are using more tan one iSCSI target, the block name (disk0, disk1 etc) is used as the disk type ...

Wait few seconds and check the new disk is visible $ lsblk --scsi NAME HCTL TYPE VENDOR MODEL REV SERIAL TRAN sda 0:0:0:0 disk ATA Samsung SSD 850 EVO 500GB EMT02B6Q S21JNXAGC13723P sata sdb 6:0:0:0 disk ASMT ST16000NM001G-2KK103 SN02 ZL22TA9C usb sdc 8:0:0:0 disk ASMT ST12000NM0007-2A1101 SN02 ZJV3CH1V usb sdd 9:0:0:0 disk ASMT WDC WD40EZRX-00SPEB0 80.00A80 WD-WCC4E0486171 usb sde 10:0:0:0 disk ASMT TOSHIBA MG07ACA12TE 0101 3010A06GF95G usb sdf 7:0:0:0 disk ASMT ST18000NM003D-3DL103 SN03 ZVT8NE6T usb Get disk WWN.

My views A satirical version of  Aniara Plot The troubled crew of Avenue 5, a space cruise ship filled with spoiled, rich, snotty space tourists, must try and keep everyone calm after their ship gets thrown off course into space and ends up needing three years to return to Earth.
