Hi, 1. Do you have all requirements #installation-requirements 2. Could you check if

open-iscsi

is installed and

iscsid

is running on all work nodes? Try

systemctl status iscsid.

3. Could you please provide us a support bundle for further investigation? You can generate a support bundle on Longhorn UI.

Hi @ripe-queen-73614, I saw

"Failed to init frontend: device pvc-db03aac2-7027-45fe-b86c-e38e85b74ad9: fail to delete target iqn.2019-10.io.longhorn:pvc-db03aac2-7027-45fe-b86c-e38e85b74ad9"

this log in the instance-manager. Could you check that

tgtd

service status and is tgtd busy? BTW I noticed that you built the system on RHEL8.6 , that may have some potential risk because it is not verified yet for Longhorn system.

@cuddly-vase-67379 how do i check that tgtd?

You could use

top

atop

to see if there any process is busy, usually

systemctl status tgtd

to check but RHEL8.6 seems use the

target

service instead.

Ref: https://github.com/longhorn/longhorn/issues/923 Maybe you could log into the corresponding engine manager pod, and manually delete the target first.

@cuddly-vase-67379 I don't see this process

systemctl status tgtd Unit tgtd.service could not be found.

Can you try to scale down the workload that are using Longhorn volumes and delete the instance-manager-e-xxx pods inside
longhorn-system
namespace?
