[SOLVED] PVE tries to connect to already deleted ISCSI target

[Accept]

Hello,

a couple of days ago I deleted a ISCSI target configured (via GUI) on my PVE and created a new one.

Now, after examining the logs the PVE tries continuously to connect to this (old) specific target and logically fails with that.

PVE 8.2.2

/etc/pve/storage.cfg:

dir: local
        path /var/lib/vz
        content vztmpl,backup,iso

lvmthin: local-lvm
        thinpool data
        vgname pve
        content rootdir,images

cifs: syn-smb-1
        path /mnt/pve/syn-smb-1
        server 10.0.3.30
        share home
        content snippets,iso,rootdir,backup,images,vztmpl
        prune-backups keep-all=1
        username pve

# new one
iscsi: syn-iscsi-0
        portal 10.0.3.30
        target iqn.2000-01.com.synology:DiskStation.Target-1.a9ad618a0fe
        content none

lvm: syn-lvm-0
        vgname syn-iscsi
        base syn-iscsi-0:0.0.1.scsi-36001405301708cdd0e11d47a7db3abd6
        content rootdir,images
        saferemove 1
        shared 1

lvm: syn-lvm-1
        vgname syn-iscsi2
        base syn-iscsi-0:0.0.2.scsi-360014050b896e89d0ee4d41ecd8506d9
        content rootdir,images
        saferemove 1
        shared 1

As far as I can estimate this, there is no storage misconfigured.

Logs:

10.0.0.30 is the "old" storage device and should not be used for ISCSI-connections anymore.

iscsiadm -m session -P 1

Any suggestions how to prevent PVE from connecting to the 10.0.0.30 device?

What I've already tried: reboot

Love u guys!

What does "iscsiadm -m node" return?

Hello!

Return of "iscsiadm -m node":

10.0.0.30:3260,1 iqn.2000-01.com.synology:DiskStation.Target-1.a9ad618a0fe
10.0.3.30:3260,1 iqn.2000-01.com.synology:DiskStation.Target-1.a9ad618a0fe
[fe80::211:32ff:fef5:b94]:3260,1 iqn.2000-01.com.synology:DiskStation.Target-1.a9ad618a0fe

This is kinda weird. I would like to remove the unused target.

I tried to logout with the command

iscsiadm --mode node --targetname iqn.2000-01.com.synology:DiskStation.Target-1.a9ad618a0fe --portal 10.0.0.30:3260 --logout

but get

iscsiadm: No matching sessions found

It makes sense because the system cannot logout a connection which is not established.

Best regards,

Phil

Have you tried

iscsiadm remove discovery-address 10.0.0.30:3260

Note: Never done this before

Hello and thanks for your reply!

I tried the command you posted but it It doesn't work:

iscsiadm remove discovery-address 10.0.0.30:3260

Try `iscsiadm --help' for more information.

I've searched for a command to delete discovery addresses and tried this:

iscsiadm -m discoverydb -t sendtargets -p 10.0.0.30:3260 -o delete


That worked for me. The session list is cleaned up now.

iscsiadm -m node:

10.0.3.30:3260,1 iqn.2000-01.com.synology:DiskStation.Target-1.a9ad618a0fe

Additionally the node summary stats are available again. That's awesome!

Thank you very much for your assist. It would have taken me a long time to figure that out for myself.

Phil
