How does the new Proxmox Backup Server (PBS) scale?
I have one specific use case in mind: a CentOS 7 LXC container mail server running Postfix/Dovecot . There is about 300 GB of data at about 3.5 million mostly small files. The volume is continually increasing.
I am aware of Dovecot...
With recent updates we are receiving rkhunter reports about /dev/.lxc-boot-id being a hidden file. Easily fixed in rkhunter but which PVE/LXC package is responsible for creating this file?
Thanks!
Thank you for replying.
Are you saying this specific container is thick provisioned? That would explain the 99.90%? I do not see this usage with other containers. Does that means those containers are thin provisioned?
How do I tell if a container is thick or thin? Looks like I'm missing the...
This probably has been asked several times but likely I am using incorrect search terms.
I'm trying to understand container disk usage differences.
I have a container that shows the following with df:
/dev/mapper/pve-vm--301--disk--1 ext4 591G 257G 304G 46%
From inside the container the...
What is the exact syntax to shrink an XP virtual disk?
I'm looking at shrinking XP KVM disks of unused disk space. There is a wiki topic, but the topic lacks specific information.
The example shows:
cp image.qcow2 image.qcow2_backup
There are no files on the host with a qcow2 file extension...
Thank you for replying.
As far as I can tell from browsing the web and this thread, running fstrim inside a container is not recommended. Instead virtual disk space should be reclaimed from the host side. Something like this in a daily or weekly cron job:
for ct in $(pct list | awk '/^[0-9]/...
Is there a preferred or recommended way to run fstrim on both LXC and KVM guests? Should fstrim be run from the host or inside guests? How often? Daily? Just before a vzdump? Do guests need to be shutdown when shrinking virtual disks? Browsing the forum and admin guide left me uncertain.
What...
Without parsing through logs, is there a straightforward way using Proxmox command line tools to know when a guest system was stopped?
Background:
When an LXC or KVM guest is stopped, the vzdump cron jobs continue to create backups. While hardly the end of the world, would be nice to determine...
Thank you for replying.
The explanation is a tad over my head as I never wandered into the API. The word "ticket" is a bit confusing as most people, including myself, associate that word with a bugzilla or subscription support request ticket.
This "ticket" is more like an SSH or HTTPS...
After upgrading Proxmox 5 to 6, I notice /etc/pve/authkey.pub is modified and rotated to authkey.pub.old, and subsequently, in /etc/pve/priv/ the authkey.key, authorized_keys, and known_hosts files all are changed every 24 hours.
Looks this lifetime limit is managed in...
Of the three Debian 10 test systems, only one exhibits the error message.
Below are sanitized copies of two of the conf files.. I see no significant differences.
All /etc/pve/firewall/*.fw files are identical.
/etc/pve/lxc/506.conf

I forgot to add in my original post that I had already tried nested.
Mysteriously, one of the systems stopped exhibiting the messages. There were full host reboots some days ago for kernel updates. All systems were rebooted.
I did find on the original behaving system the pve firewall was...
Proxmox 5.4, fully updated.
I am prototyping three Debian 10 containers.
In two of the systems I see the log spew noted in the thread title. In one system I don't.
Poking around the web indicates the solution is PrivateTmp=false. I configured all three systems with that parameter and...
The default sysctl rp_filter configuration is 2 (loose) set in /usr/lib/sysctl.d/pve-firewall.conf. Changing the setting to 1 (strict) in /etc/sysctl.conf results in not being able to ping one Proxmox system. Changing to 1 did not affect other Proxmox systems.
Where do I start poking and...
We're running 5.x fully updated.
I suspect the trigger is caused by privileged containers. In your test did you use unprivileged?
We use privileged containers to support NFS.
