@Sebastian-Roth said in FOG on LXC:

@gusto Thanks for clarifying! As I see this post is from Nov 1, 2018 - some time after I have used LXC myself. I don’t have a Proxmox server at hand so I can’t try myself, sorry.

• Do you get any error messages?
• What output do you get when running showmount -e in the FOG LXC container?
• Have you tried mounting the NFS share from another machine?

Hi
So again, I have a problem destroying the LXC
I installed FOG without any problems

yum install git -y
cd ~
mkdir git
cd git
git clone https://github.com/FOGProject/fogproject.git
cd ~/git/fogproject/bin
./installfog.sh

I admit that I can destroy the LXC now.
However, now I want to install linux mint over pxe and do this as instructed.
Then I can’t destroy the LXC and get the output

TASK ERROR: lvremove 'pve/vm-111-disk-0' error:   Logical volume pve/vm-111-disk-0 contains a filesystem in use.

showmount in the LXC show

Export list for fog-server:
/images/dev *
/images     *

@gusto Can you explain why you keep on wanting to destroy the the container??

@Sebastian-Roth
I’m just doing a test. If something doesn’t work, I want to destroy the LXC, but I can’t destroy it because

TASK ERROR: lvremove 'pve/vm-111-disk-0' error:   Logical volume pve/vm-111-disk-0 contains a filesystem in use.

@gusto When you see this error message can you run lsof | grep vm-111-disk and post the output here?

This is not at all a FOG specific question and while we try to help I have to say that there are forums out there knowing a lot more about LXC then we FOG people do. Chance is high you get a better answer in a different forum on this specific question!

@Sebastian-Roth
This command gives nothing to output

[root@fog-server ~]# lsof | grep vm-111-disk
[root@fog-server ~]# 

Of course I put this question on the proxmof forum, but I didn’t get the answer (see my first post).

very thx

[Sebastian Roth]

@gusto Don’t run the command within the fog-server but on your proxmox host after you have tried to destroy it. Make sure you use the right VM ID. It might not be 111 anymore if you keep destroying and re-creating it.

@gusto This is run on your Proxmox server console???

[gusto]

@Sebastian-Roth
Yes on proxmox
