I had my Proxmox machine use a pair of HDDs in RAID1 to use for storing media files and it was set up as storage for Proxmox so my containers could use it. I had 4TB to use for storing media and I would have a container mount that drive. I wanted to update PVE from 8 to 9, so I backed up containers and copied the files from /etc/ that the wiki mentioned for upgrading. I tried to do the in-place upgrade, but I think it broke things, so I did a new installation. When I upgraded, I restored my container and it's like before, but I don't know where my files are that were on the HDDs. I mounted them to try to look for the files, but I can't find them, I can only see
Code: 
dump  images  lost+found  private  snippets  template

Where are the files I saved? Why can't I just see files like I would with any disk drive?
 
I don*t understand:
a) you use raid1 on 2x HDD with what file- and Raid-Ssystem, mdadm, ext4, xfs?
b) And you have a other 4 TB HDD?
c) Where are your backup are saved? Can you tell us that?
d) on with device where and is now your Proxmox VE System is installed?
e) Do you know of the file in the tree of /var/lib/vz/ ?
 
b) And you have a other 4 TB HDD?

No, I only have one pair of HDDs that I was using to store media files and they're 4TB. I saved backups on flash drives and the PVE system is on a SSD that I use for system stuff and ISO images
Do you know of the file in the tree of /var/lib/vz/

I don't understand

This is the old file I saved on USB. The "library" directory is what I used for the media disk drives on HDDs.

Another question: where have you mounted them? That is, in which directory on the PVE host?
 
Please share
Bash: 
lsblk -o+FSTYPE,LABEL,MODEL
zpool status -vtLP
zfs list
df -hT

Have you checked what is in these directories?

Yeah, they're all empty, except for images, which has some container backups: 100, 101, 102.

The 4TB drive is mounted in /etc/pve/library

Sorry, that was supposed to be zpool status. Since the HDD is already mounted I guess we can check its contents
Bash: 
apt -yU install gdu
gdu /mnt/pve/library
Can you also share the CT config via pct config CTIDHERE?

Well, let's go on a tangent then and fix your DNS first. Share
Bash: 
cat /etc/network/interfaces
cat /etc/resolv.conf
Click to expand...
Code: 
cat /etc/network/interfaces
auto lo

auto vmbr0

        bridge-ports nic0
        bridge-stp off

iface nic1 inet manual

Code: 
cat /etc/resolv.conf
search lan

No need to quote each of my messages.
Try to replace
Bash: 
nameserver 192.168.1.19
with
Bash: 
nameserver 192.168.1.254
You can also set this in the GUI via node > System > DNS. If that doesn't work either use 1.1.1.1. Then continue with the gdu stuff from earlier.

That worked and I installed gdu. This is what returns from the pct command

Code: 
arch: amd64
cmode: shell
cores: 3
features: nesting=1
hostname: Media
memory: 4768
mp1: library:100/vm-100-disk-2.raw,mp=/media,backup=1,size=3000G
net0: name=eth0,bridge=vmbr0,firewall=1,hwaddr=BC:24:11:B2:CA:AF,ip=dhcp,type=veth
onboot: 1
ostype: debian
rootfs: local-lvm:vm-100-disk-0,size=12G
swap: 1024
unprivileged: 1
unused0: local-lvm:vm-100-disk-1

I navigated with gdu and inside the images directory, there's 3 files with the largest being in the CT100 directory containing vm-100-disk-0.raw

So the images are there. Try pct rescan and check pvesm list library.
