Please note that this is more readable when using CODE-tags. It appears that the virtual disk-0 of container 100 is indeed does not exist.
Do you have a backup of container 100? What happened? Did you delete the disk? Did your system crash?
 
Thanks for the quick reply, not understanding anything in proxmox I wouldn't know what you mean by using CODE-tags.The disk, or rather the disks crashed last week and instead of 4 it was telling me there were 2 and I deleted everything, changing the raid2 type. I can't retrieve the backup of container 100 . although it was an experiment , so I would also gladly do it again, but how can I do since on gives me the option to delete it?

That is not about Proxmox but about this forum. Have a look at the buttons above the part where you type your messages.

So your disks crashed and you lost the data, thank you for clearing that up. Maybe reinstall Proxmox and start again with only the working disks?
 
I don't think that in case of errors like this the only possibility is to delete everything and redo.Is it possible that there is no metoro to delete the CT (100) and redo it from new ?

Just delete it? Or, if all virtual disk are already deleted/missing, just delete the configuration /etc/pve/lxc/100.conf.
 
deleted because it was no longer working , but I don't see any file in /etc/pve/lxc/100.conf

Then your Proxmox is broken and I don't know how to fix it. Maybe someone else here knows.
