Cannot add iso to VM - no storage found?

[DeepB]

Hello,

I have a few ISOs on a local storage (shown as local(HOSTNAME) in the webinterface). The ISOs are shown in the webinterface.

However when I want to add a drive to a VM I chooese "Use CD/DVD disc image file (iso) " and then try to choose the storage. It says "loading" for quite some time (20 sec?) and then shows no storage.



Any idea how to correct that?

thanks
Daniel

Hi,
do you have 'ISO image' enabled as content for local storage (check under Datacenter->Storage->local)?
If that is not the problem, please provide the output of `cat /etc/pve/storage.cfg`.

There are already ISO-files on that storage that are mounted in VMs as cdroms. I just cannot add the ISO to new VMs or new ISOs to the existing VMs.

root@pve2:~# cat /etc/pve/storage.cfg
dir: local
        path /var/lib/vz
        content iso,backup,vztmpl

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

rbd: SSD
        content rootdir,images
        krbd 0
        pool SSD

rbd: data
        content rootdir,images
        krbd 0
        pool data

cephfs: cephfs
        path /mnt/pve/cephfs
        content vztmpl,backup,iso

Also:

root@pve2:~# ls /var/lib/vz/template/iso/
alpine-standard-3.10.1-x86_64.iso  SW-17.5.7_MR-7-511.iso

Okay, maybe your cephfs is interfering (question mark in WebUI)? Do you get any errors in the syslog? What is the output of `pvesm status`?

 

[DeepB]

cephfs is old, I deleted it, it just still shows up in the webinterface.

Adding the iso on the command line works.

qm set 103 -cdrom /var/lib/vz/template/iso/SW-17.5.7_MR-7-511.iso

pvesm status does not return anything. it just hangs until I end it with ctrl+C

Okay than clearly something is off with your storage. Do you see any error messages in the syslog?

I have a few of those:

Other thatn That I do not see any errors. What am I looking for?

 

[Chris]

Hmm, okay so no relevant errors... As next step you can try to remove the cephfs entry from the /etc/pve/storage.cfg and see if that solves your issue. Simply prefix the corresponding lines with # in the config
