[SOLVED] Migration failure due to ISO storage

[n01k]

Hello everyone, I have seem to run into an issue that I cannot recovery from at this time.

Last week, I wanted to migrate a VM from one host to another. I tried to do so but was abrulplly told that it cannot happen due to the following:

Used shared storage 'QNAPISO' is not online on source node!
2021-02-19 14:47:27 starting migration of VM 105 to node 'PROXHOST' (10.16.61.104)

TASK ERROR: migration problems


Now I realize that the QNAPISO shared storage was a problem so I tried to remove it and this is what I was left with:





I have tried to remove the CD/DVD Drive but it won't remove. I have removed the QNAPISO path from the storage view.


I have gone and deleted the lock for file 105 but I can't the VM to shut down or anything.








root@PROXHOST:/var/lock/qemu-server# cd /run/lock/qemu-server/
root@PROXHOST:/run/lock/qemu-server# ls
lock-104.conf lock-105.conf lock--1.conf
root@PROXHOST:/run/lock/qemu-server# rm lock-105.conf
root@PROXHOST:/run/lock/qemu-server# ls
lock-104.conf lock--1.conf




Any ideas or suggestions on how I can get this VM to shutdown?

I cannot enable QNAPISO anymore.



Thank you

qm unlock 105 then qm shutdown 105 should do the trick. For best results, don't go around deleting random lock files

I have tried to remove the CD/DVD Drive but it won't remove. I have removed the QNAPISO path from the storage view.

IDE CD drives are not hotpluggable, which is why they require a full VM reboot. After that, migration should be working.

Thank you Stefan for the reply.

I will not delete random files anymore, I was just going based on some search results.

I just tried the above command and my putty session just sat there after I ran qm shutdown 105

oot@PROXHOST:~# qm unlock 105
root@PROXHOST:~# qm shutdown 105
^CVM quit/powerdown failed
root@PROXHOST:~#

I've found my own solution to this and am able to have my VMs functional now. For anybody coming across this post in the future, this worked for me.

Seeing as I was getting an error regarding the following that I tried to remove:

ide2: QNAPISO:iso/virtio-win-0.1.171.iso,media=cdrom,size=363020K

I have tried qm unlock 105 and qm shutdown 105 without success.

I tried to run QM shutdown 105 but it failed.

root@CALNPROXM01:~# qm shutdown 105
VM quit/powerdown failed


I found a discussion regarding the VM configuration file located at:

/etc/pve/qemu-server/<VMID>.conf

So I read the config file for VM 105 and found the ide2 line, which was pointing to a QNAP source that is no longer existent.

I removed the the line for ide2 and saved my configuration.

I ran qm stop "VMID"

Immediatly, the VM powered off.
I powered it back on and it's up and functional now.


My only concern with proxmox is that if IDE drives are not Hot-Swappable, the system should error out when the user tries to remove it from the system. This was my fault but I was not aware of such.


Anyways, thank you.
