Hi I have an existing proxmox 6.4 node with containers and vms which I have converted to a cluster to add a new node. This original node is using local-lvm thin for the guests (so basically I have local and local-lvm storages). The new node is having ZFS storage, one single raidz1, and I see on...

Same error here, latest pve6 version. After 1 hour I reboot the server

Hi there. I remember reading in another thread in this forum that. this was not an Proxmox issue but some kind of bugs between lxcfs and cgroups2 or something like that but I am now unable to find the thread. For me, as all my containers are monitored from custom agents inside the container for...

@mathx Thanks very much for the workaround. I am a little reluctant to do this on a production server, but to be honest having to restart containers on a weekly basis is really a problem, so I will check this out.

Same problem here, all my containers are silently taking more memory in cache until oom-kill kicks in. This happens in all my containers but in pve6. In my case, restarting systemd-journald did not help, however reducing journals log size increased the available memory by the same size I...

Simply put, because we do not have the knowledge yet, but thanks for the tip

Both performance and flexibility. VM take a performance hit compare to containers and we would like to avoid it. Also containers are fully deployed automatically via ansible in most of the cases; if we need an extra "server" we just provision a new container in a couple of minutes in...

Hi i am planning to migrate a virtual server from VM to LXC on my production cluster. This VM is currently having about 30K active tcp connections on peaktime which is no big issue for a vm, but, is there any specific recommendations or concerns for LXC guest or Node host in order to deal with...

Hi have not tried H750 sorry, but I am using H720P in all my servers, 14 Dell R620 and the Perc works ok. I do not see any reason why it should not as long as the linux kernel recognizes it, in any case.

Hi all I have a 3 node-cluster for my development environment, all three nodes are basically same hardware. Cluster is pve6 and all lxc containers are centos7. In one of the nodes, all the containers have 0 swap memory, no matter what the configured amount is for any lxc. The main node las 16GB...

Yep, fully agree, just asking :-)

Hi all After having the same problem and fixing it as described in this post, now i have the opposite one; the load inside the container is propagated to the host. I have a 4 cpu container which launches 70 threads, most of them waiting for cpu to be available. The container is using the 4...

Hi all. as Urnash mention the fstrim.timer service is not running in a default installation. no matter if it is suscription or community edition. Is it safe to activate it? systemctl list-timers -all systemctl start fstrim.timer systemctl start fstrim.service

Thanks both. I have been doing a lot of digging and test into this: The first conclusion is Memory Usage chart in Proxmox WebUI is misleading as it does not reflect shared memory. As @Dunuin mentioned shared memory is not free memory, but as not shown in the chart I was heavily...

Hi I have a 3 node cluster as development environment; all the nodes are basically 200GB RAM, 48 cores dell R620. I have found recently that in one of the nodes, OOM is killing always the same daemon running inside an lxc container and also a VM. The host has a lot of empty ram, taking a...

Hi i am going to deploy proxysql in my Proxmox cluster, it will be done using KVM and not lxc in order to be able to use VRRP to get H/A between several VMS in different nodes of the cluster. Is there any recommendation to the VM hardware setup, the Proxmox node itself or the VM configuration...

Worked like a charm. Thanks!

This cluster is my TEST env with two nodes. CPU(s) 48 x Intel(R) Xeon(R) CPU E5-2697 v2 @ 2.70GHz (2 Sockets) Kernel Version Linux 5.3.13-3-pve #1 SMP PVE 5.3.13-3 (Fri, 31 Jan 2020 08:17:11 +0100) PVE Manager Version pve-manager/6.2-4/9824574a I am trying to avoid restarting the node...

Hi I have a 2 node cluster with pve6.2, it is working ok, both nodes are showing the green tick and i can connect to both via ssh or via webUI. Nodes can see each other in the networking. In one node all LXC containers are showing a question mark under a grey circle. However the containers are...

Hi there I have a LXC container which uses last access time to implement sort of LRU image cache; images not accessed in X days are automatically deleted. I have cloned the container, moved into another PMX node, shutdown the original one, and start the cloned container in the PMX, but the...
