[SOLVED] Error: unable to create rrdb stat dir - EACCES: Permission denied - Clean PBS v2 Installation

[StackIOI]

I'm trying to run PBS v2.x directly in a LXC running Debian 11. Already have a PBS v1.x instance running in another LXC running Debian 10, so I thought to give it a try with the new version... What steps did a take? Here a summary:

1. create lxc using template debian-11-standard_11.0-1_amd64.tar.gz
2. resources: arch: amd64 / cores: 2 / hostname: prxmxbs / memory: 2048 / mp0: /media/usb-hdd/pbs,mp=/media/usb-hdd / net0: name=eth0,bridge=vmbr0,firewall=1,hwaddr=[redacted],ip=dhcp,type=veth / ostype: debian / rootfs: local-lvm:vm-900-disk-0,size=16G / swap: 1024
3. options" privileged [also tried unprivileged] / features: none
4. inside the lxc:
   - wget https://enterprise.proxmox.com/debian/proxmox-release-bullseye.gpg -O /etc/apt/trusted.gpg.d/proxmox-release-bullseye.gpg
   - edit /etc/apt/sources.list.d/pbs-enterprise.list
   #deb https://enterprise.proxmox.com/debian/pbs bullseye pbs-enterprise
   - edit /etc/apt/sources.list
   deb http://download.proxmox.com/debian/pbs bullseye pbs-no-subscription
   - apt update && apt install -y proxmox-backup [also tried with proxmox-backup-server]
5. tried https://server-ip:8007/ - but got a "ERR_CONNECTION_REFUSED"

Where is that rrdb stat dir supposed to be created and why is it failing? Any help is greatly appreciated!

I stick to it, I also have a problem with it.

 

[dcsapak]

yeah it seems to be a bug in how (or better: where) we create the directory

you can workaround by creating the directory: '/var/lib/proxmox-backup/rrdb' and make it belong to the 'backup' user and group by doing:

chown backup:backup /var/lib/proxmox-backup/rrdb

That did it... thanks for the help!

same bug today, and same "Failed to start Proxmox Backup API Proxy Server"
and also this workaround works for me

thanks for the help
