Hello, I deleted linstor\_db on node3. How can I safely add linstor\_db again without damaging the system and ensure that linstor\_db does not report as StandAlone? ```auto root@node1:~# linstor storage-pool list ╭─────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────╮ ┊ StoragePool ┊ Node ┊ Driver ┊ PoolName ┊ FreeCapacity ┊ TotalCapacity ┊ CanSnapshots ┊ State ┊ SharedName ┊ ╞═════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════════╡ ┊ DfltDisklessStorPool ┊ node1 ┊ DISKLESS ┊ ┊ ┊ ┊ False ┊ Ok ┊ node1;DfltDisklessStorPool ┊ ┊ DfltDisklessStorPool ┊ node2 ┊ DISKLESS ┊ ┊ ┊ ┊ False ┊ Ok ┊ node2;DfltDisklessStorPool ┊ ┊ DfltDisklessStorPool ┊ node3 ┊ DISKLESS ┊ ┊ ┊ ┊ False ┊ Ok ┊ node3;DfltDisklessStorPool ┊ ┊ drbd-zfs-sas0 ┊ node1 ┊ ZFS ┊ data_sas0/drbd ┊ 317.33 GiB ┊ 464 GiB ┊ True ┊ Ok ┊ node1;drbd-zfs-sas0 ┊ ┊ drbd-zfs-sas0 ┊ node2 ┊ ZFS ┊ data_sas0/drbd ┊ 317.33 GiB ┊ 464 GiB ┊ True ┊ Ok ┊ node2;drbd-zfs-sas0 ┊ ┊ drbd-zfs-ssd0 ┊ node1 ┊ ZFS ┊ data_ssd0/drbd ┊ 1.68 TiB ┊ 1.73 TiB ┊ True ┊ Ok ┊ node1;drbd-zfs-ssd0 ┊ ┊ drbd-zfs-ssd0 ┊ node2 ┊ ZFS ┊ data_ssd0/drbd ┊ 1.68 TiB ┊ 1.73 TiB ┊ True ┊ Ok ┊ node2;drbd-zfs-ssd0 ┊ ╰─────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────╯ root@node1:~# linstor resource list ╭───────────────────────────────────────────────────────────────────────────────────────────────────────╮ ┊ ResourceName ┊ Node ┊ Port ┊ Usage ┊ Conns ┊ State ┊ CreatedOn ┊ ╞═══════════════════════════════════════════════════════════════════════════════════════════════════════╡ ┊ linstor_db ┊ node1 ┊ 7000 ┊ InUse ┊ StandAlone(node2) ┊ UpToDate ┊ 2024-06-18 15:26:05 ┊ ┊ linstor_db ┊ node2 ┊ 7000 ┊ InUse ┊ StandAlone(node1) ┊ UpToDate ┊ 2024-06-18 15:26:05 ┊ ┊ pm-0b7a526a ┊ node1 ┊ 7003 ┊ InUse ┊ Ok ┊ UpToDate ┊ 2024-06-18 22:58:44 ┊ ┊ pm-0b7a526a ┊ node2 ┊ 7003 ┊ Unused ┊ Ok ┊ UpToDate ┊ 2024-06-18 22:58:49 ┊ ┊ pm-c497f25f ┊ node1 ┊ 7004 ┊ InUse ┊ Ok ┊ UpToDate ┊ 2024-06-18 23:07:47 ┊ ┊ pm-c497f25f ┊ node2 ┊ 7004 ┊ Unused ┊ Ok ┊ UpToDate ┊ 2024-06-18 23:07:52 ┊ ┊ pm-d14f5a7f ┊ node1 ┊ 7006 ┊ InUse ┊ Ok ┊ UpToDate ┊ 2024-06-18 23:27:16 ┊ ┊ pm-d14f5a7f ┊ node2 ┊ 7006 ┊ Unused ┊ Ok ┊ UpToDate ┊ 2024-06-18 23:27:23 ┊ ┊ pm-ebd55187 ┊ node1 ┊ 7005 ┊ InUse ┊ Ok ┊ UpToDate ┊ 2024-06-18 23:20:18 ┊ ┊ pm-ebd55187 ┊ node2 ┊ 7005 ┊ Unused ┊ Ok ┊ UpToDate ┊ 2024-06-18 23:20:25 ┊ ╰───────────────────────────────────────────────────────────────────────────────────────────────────────╯ root@node1:~# linstor resource-group list ╭───────────────────────────────────────────────────────────────────────╮ ┊ ResourceGroup ┊ SelectFilter ┊ VlmNrs ┊ Description ┊ ╞═══════════════════════════════════════════════════════════════════════╡ ┊ DfltRscGrp ┊ PlaceCount: 2 ┊ ┊ ┊ ╞┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄╡ ┊ drbd-zfs-sas0 ┊ PlaceCount: 2 ┊ 0 ┊ ┊ ┊ ┊ StoragePool(s): drbd-zfs-sas0 ┊ ┊ ┊ ╞┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄╡ ┊ drbd-zfs-ssd0 ┊ PlaceCount: 2 ┊ 0 ┊ ┊ ┊ ┊ StoragePool(s): drbd-zfs-ssd0 ┊ ┊ ┊ ╞┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄╡ ┊ linstor-db-grp ┊ PlaceCount: 2 ┊ 0 ┊ ┊ ┊ ┊ StoragePool(s): drbd-zfs-sas0 ┊ ┊ ┊ ┊ ┊ DisklessOnRemaining: True ┊ ┊ ┊ ╰───────────────────────────────────────────────────────────────────────╯ ``` ---

You will need to: 1. Find the “good” controller instance: ```auto linstor controller which ``` 2. disable the HA configuration **on the other node** : we need to resolve the split brain by discarding the data there. ```auto drbd-reactorctl disable --now linstor_db drbdadm disconnect linstor_db drbdadm secondary linstor_db drbdadm connect --discard-my-data linstor_db ``` 3. Reconnect the resource on the “good” controller: ```auto drbdadm disconnect linstor_db drbdadm connect linstor_db drbdadm status linstor_db ``` The nodes should begin to sync and quickly be back to UpToDate state. 4. Reset the tiebreaker flag: ```auto linstor resource-definition set-property linstor_db DrbdOptions/auto-add-quorum-tiebreaker linstor resource list ``` There should now be a diskless tiebreaker resource on `node3`. 5. Re-enable the HA configuration on all nodes ```auto drbd-reactorctl enable linstor_db ``` ---

Hi, thank you very much. It saved my situation. I have one last question: if I wanted to cancel the HA Linstor controller and move the Linstor controller to node3 only, what is the correct procedure? I am interested in the technical aspect of how I would migrate.
