I've configured a freeNas with iSCSI and two nodes connecting to that device. Everithing it's ok but after reboot I can't see with lsblk:

lsblk
NAME          MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
sda             8:0    0   35G  0 disk
├─sda1          8:1    0    1G  0 part /boot
└─sda2          8:2    0   34G  0 part
  ├─rhel-root 253:0    0 30,5G  0 lvm  /
  └─rhel-swap 253:1    0  3,5G  0 lvm  [SWAP]
sr0            11:0    1  4,2G  0 rom

iscsiadm -m discovery -t st -p 192.168.1.171
192.168.1.171:3260,1 iqn.2005-10.org.freenas.ctl:controlm


[root@nodo2 ~]# iscsiadm -m session -P 3 | grep 'Target|disk'
Target: iqn.2005-10.org.freenas.ctl:controlm (non-flash)
                Target Reset Timeout: 30
                        Attached scsi disk sdb          State: running

Thanks

You have discovered the target. It should be connected (login) as the next step.

iscsiadm -m node -l -T iqn.2005-10.org.freenas.ctl:controlm

Check the connected targets:

iscsiadm -m session

  • I have session connected, but I can't see it: [root@nodo2 ~]# iscsiadm -m session tcp: [2] 192.168.1.171:3260,1 iqn.2005-10.org.freenas.ctl:controlm (non-flash) – Miguel7799 Mar 22 '24 at 10:12
  • This output shows that you have session connected. Do you see the block device if your run lsblk? – Stuka Mar 22 '24 at 12:42
  • I can't see it: lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 35G 0 disk ├─sda1 8:1 0 1G 0 part /boot └─sda2 8:2 0 34G 0 part ├─rhel-root 253:0 0 30,5G 0 lvm / └─rhel-swap 253:1 0 3,5G 0 lvm [SWAP] sr0 11:0 1 4,2G 0 rom – Miguel7799 Mar 23 '24 at 07:36
  • I missed the part about 2 nodes. Do you have LVM configured or some kind of cluster file system? You can try running partprobe on this node. If you are using clustered LVM, try pvscan --cache – Stuka Mar 27 '24 at 11:54
