FOG on LXC
-
- I would like to install FOG on LXC (Proxmox 5.4.13). According to this instructions we need to enable it
Options --> Feature --> Nestig - ON
This setting ensures the NFS server functionality inside LXC.
Do I need also to install NFS on a host (proxmox)? - According this, components will be automatically downloaded and installed by the FOG installation script: PHP 5/6/7, MySql 5+, Apache 2+, DHCP (any!), TFTP, FTP, NFS. I already have a DHCP server set to mikrotik. At the bottom of the web site is listed
This works for FOG too by the way you just have to use "undionly.kpxe" instead of "pxelinux.0"
That means I have to change pxelinux.0 to undionly.kpxe? - I have tentatively installed NFS in LXC (centos 7). Then I wanted to destroy the LXC, but I couldn’t destroy the LXC because filesystem in use.
Can anyone advise me?

@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.

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

@gusto When you see this error message can you run
lsof | grep vm-111-diskand post the output here?https://itsol.biz/lvm-problem-logical-volume-contains-filesystem-use/
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!

I’m just doing a test. If something doesn’t work, I want to destroy the LXC, but I can’t destroy it becauseTASK ERROR: lvremove 'pve/vm-111-disk-0' error: Logical volume pve/vm-111-disk-0 contains a filesystem in use. -
@gusto Can you explain why you keep on wanting to destroy the the container??

@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 -ein 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 problemsyum install git -y cd ~ mkdir git cd git git clone https://github.com/FOGProject/fogproject.git cd ~/git/fogproject/bin ./installfog.shI 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 outputTASK 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 * -
@george1421
very thankyou -
-
Now everything is all right. I am currently looking for a tutorial on how to set up FOG so I can install various OS over PXE
-
@gusto So is there anything we can do for you?

This happened to me before I installed centos 7 from the template and NFS according to the instructions.
Now that I have installed FOG, I will destroy the LXC without any problems. However, I have a plain FOG installed without any settings. -

Look at here, there is a link at proxmox forum topis 10 -
@gusto I am not sure I can follow your questions.
According to this instructions we need to enable it
Options --> Feature --> Nestig - ONWhere did you read about “Nesting”? Can see anything about this in the linked wiki article. Did you follow the instructions mentioned in the wiki about Apparmor?
Do I need also to install NFS on a host (proxmox)?
I have done a LXC installations a couple of years ago but can’t remember this part anymore. If it’s not in the wiki I don’t think it’s needed.
That means I have to change pxelinux.0 to undionly.kpxe?
Yes, use
undionly.kpxefor legacy BIOS machines andipxe.efifor UEFI machines. Also see https://wiki.fogproject.org/wiki/index.php?title=BIOS_and_UEFI_Co-Existence and my post here: https://forums.fogproject.org/post/130612I have tentatively installed NFS in LXC (centos 7). Then I wanted to destroy the LXC, but I couldn’t destroy the LXC because filesystem in use.
Not sure how to solve this. Not great but rebooting the whole server should definitely fix it.
