iSCSI target clean-up (removal)

[HPmoss]

I was experimenting with iSCSI target and while trying to move I made a rookie mistake of deleting the folder first instead of gracefully cleaning it. I had tgt installed on the system that I have uninstalled. Can some please help me fix the issue, just trying to clean up the mess. I am not an expert in tgt/iSCSI targets. Logs from Proxmox listed below:

Hi @HPmoss , its not quite clear to me what you did or the state you are in.

In general, you should:
- check your mount points: mount
- check iscsi sessions and nodes: iscsiadm -m session && iscsiadm -m node
- check storage config : cat /etc/pve/storage.cfg
- check storage status: pvesm status
- the mount point that is being unmounted is busy, this could be due to running VMs. You can a) reboot the system b) find out why its busy "linux open files" in google

There is nothing in your log that would indicate an iSCSI error, except the names of your mount-moints, which could be completely arbitrary. Frankly, if this is not a critical production system - reboot it.

Restarted the box couple of times. No joy so far.
The mount point is stuck and I am unable to remove it.

If you are able to execute earlier suggested steps and provide their output as Text encoded in CODE tags, available via menu of the edit box, perhaps someone in the community can provide additional suggestions.

Cheers
