Thanks @ness1602 . The question is in general but in this case we are having CPU issues. Some other times could be RAM. The question is how to isolate it per container to at least know which is causing the issue rather that the process itself as for example we have apache in many of them or php...

This might be more an LXC question but I was wondering what are the key forensic commands when the pve server becomes unstable or with a high activity. When running 6-10 containers, how can we have a generic view of their activity together apart from the web interface. I understand there was a...

Hi. I've read the numerous threads regarding apparmor flooding syslog with messages related to actions not allowed to be performed inside containers but can't figure still how to reduce os investigate and only seem to find the solution of ignoring with conf on syslog. In this case is a new PVE6...

Currently upgrading a server to PVE6 and trying again to understand where is tmpfs taken from on a container. Is that tmpfs assignment coming from the total allocation of the container or from the host?

Thanks @wolfgang. Yes we are in the process of upgranding. In this case we believe the issue was probably related to a leak on a cache that was wrting to a tmpfs partition that grew too much. I've asked about it on https://forum.proxmox.com/threads/memory-use-of-containers-and-tmpfs.72696/ It's...

We are trying to debug some memory issues with a container and best practices to monitor Within the PVE interface I see Memory usage 11.59% (949.30 MiB of 8.00 GiB inside the container: cat /proc/meminfo MemTotal: 8388608 kB MemFree: 2967096 kB MemAvailable: 7401044 kB...

We've been using Debian as base os within LXC containers for a while with no issues. Since we updated Debian to version 10 on some of them and now on a new Ubuntu 20 template we keep having issues mainly with services configuration and namespacing issues. We thought that by using a fresh...

Hi. Sorry to jump on this post but I am quite interested in the fail2ban/csf/lfd on the lxc containers. We currently run CSF on the host and on the containers with public and private ip address at OVH. We understand the firewall part is somehow redundant on the private (10.0.0.X) containers as...

We are stuck with some sudden regular hangs of a container running mainly apache and mysql for a website. We are not sure if directly related to an upgrade of the container to Buster, after a few hours the container becomes unstable, Mysql hangs and after a while the whole system becomes...

Not sure what you mean. Is native bind mount supported in KVM if using ZFS?

Thanks for prompt reply. I assume then LXC / LVM not suitable. My problem with KVMs is bind mounts and not being able to share files with host system. i already asked a few months back regarding VirtFS - 9p which I understand is still not supported by the kernel as an alternative. NFS or...

There is so many entries regarding Docker on PVE over the last years that I would be most grateful if someone can point at the best method to have a basic Docker server running inside an LXC Container within PVE6 (if possible or 5 if required), ideally unprivileged but initially trying to get it...

Thanks. I did use FIO at the time before deciding storage formats and results were better or at least not x5 times slower ever , especially compared to a similar mdadm + lvm over 2 ssds. I'll try to repeat the tests with FIO and maybe try to adjust on of the two raids that show low figures on...

Thanks Alwin. Can you clarify that. I mean, the root partition access should be the same for all mount points. All containers are thin provisioned there. A second one with bad results (same raid+lvm behind) has no containers running on it. I could test with all containers stopped or from a...

After some struggling to get our setup running over two NVMe PCIe x4 units (https://forum.proxmox.com/threads/i-o-errors-with-nvm-drives.64974/#post-294108) and although we are reasonably happy with the system I've just discovered that the performance returned by pveperf /FSYNCS/SECOND are...

Not having "bind type" mount points from hots to VM has always been one of our main pullbacks from using KVM more extensively. I am trying to avoid NFS, sftp or SAMBA as an option and have just been reading about VirtFS - 9p virtio drivers (http://www.linux-kvm.org/page/9p_virtio) I've found...

That's great news, thanks. I managed to update the NVMs MP600 firmware (via Windows PE rescue) and the problem seem to have stopped (reporting at least). Update to latest kernel now and all seems working fine. Thanks.

Current kernel used: 5.3.13-3-pve I seem to having some ocassionall I/O errors issues with my NVM pci-e 4 drives (Corsair MP600 on a ASUS Pro WS X570-ACE motherboard) that I've come to determine that could be related to some kernel trim support of NVM drives as reflected on kernel bug...

Hi @LnxBil. Thanks for the feedback. Understanding the differences I still think that Proxmox / LXC would benefit in the long term of supporting running Docker hosts on containers if that was properly isolated. As for "sharing documents" more or less what you mentioned. We currently do via...

As others on this forum we've been considering for a while migrating some installations to docker containers and also like other I would hope to be able to do it within the Proxmox setup. I was wondering if the new Proxmox 6 brings any updates or changes to this. As far as I understand Proxmox...
