Is the a tool which shows the actual disk IO on LXC / Container basis? iotop shows on process basis and so we do have to do cat /proc/NNNN/cgroup is there a tool which shows this values per container?

Thanks we will read. We see there is no out of the box solution. with KVM VM it is possible?

No, how to do?

wrong thread please delete

Is there a way in Proxmox to limit IO of LXC Container? It is on ZFS. Somethink like lxc config device set ci root limits.read 30MB lxc config device set ci root limits.write 10MB do not work. there is no lxc command. we did not find any in this forum. Thanks so much.

sadly not. we have in hosts 192.168.0.1 storage1 192.168.1.1 storage1 192.168.0.2 storage2 192.168.1.2 storage2 192.168.0.3 storage3 192.168.1.3 storage3 some weeks ago added all nodes to the cluster via pvecm add 192.168.0.1 -link0 192.168.1.2 -link1 192.168.0.2 Membership information...

Same Problem with Proxmox 5->6 we change the /etc/default/zfs But update-initramfs not found. so if we reboot, nothing changed. what can we do?

Thanks. "Check that you have both IPs in your /etc/hosts and you can login with ssh from both networks." do you mean to hosts? 192.168.0.2 storage2 192.168.1.2 storage2 This does not help. May Proxmox GUI think the nodes are on 192.168.0.N .. in GUI cluster -> Overview the nodes are listed...

Thanks. Only Corosync works well. Thanks, IPs are examples. Corosyn all is fine with tinc now. But we have other "Problems". We use eth0 for corosync and eth1 is used for proxmox internal net (communicate to hosts / nodes) and it is internal net for KVM VMs. So if eth1 is down, corosync eth1...

Thanks. Any suggestions with VPN? We testet with tinc. But it high cpu if we test high traffic on this net. 2nd: Sadly we have no access to infrastructure in our datacenter. So VPN is the only way we see.

Thank you so much.

We have 3 nodes with 2 private nics eth0 - 192.168.0.0/24 corosync link 1 , ceph storage, proxmox gui and clustercommunication f.e migration eth1 - 192.168.1.0/24 corosync link 0 we have set corosync nodes to have 2 rings (ring0_addr: 192.168.1.2 / ring1_addr: 192.168.0.2). this works well...

ok, but with ifconfig inetVPN mtu 1445 it works. any objections against the use of MTU 1445 ?

We use proxmox 6 , this is with corosync 3 we think.

proxmox-ve: 6.0-2 (running kernel: 5.0.15-1-pve) pve-manager: 6.0-4 (running version: 6.0-4/2a719255) pve-kernel-5.0: 6.0-5 pve-kernel-helper: 6.0-5 pve-kernel-4.15: 5.4-6 pve-kernel-5.0.15-1-pve: 5.0.15-1 pve-kernel-4.15.18-18-pve: 4.15.18-44 ceph: 14.2.1-pve2 ceph-fuse: 14.2.1-pve2 corosync...

ifconfig inetVPN mtu 1445 seems solve the problem. we like to understand what is the reason? tinc PING and PONG, so may the packege are to big? ifconfig inetVPN mtu 1500 produce the error see above

We get many of this errors. Aug 02 07:41:54 storage1 corosync[3283]: [KNET ] pmtud: possible MTU misconfiguration detected. kernel is reporting MTU: 1500 bytes for host 4 link 0 but the other node is not acknowledging packets of this size. Aug 02 07:41:54 storage1 corosync[3283]: [KNET ]...

we have ips like 52.78.. 52.76 and so on

We have 3 Nodes. Each has eth0 with public ip and eth1 with private. no more NICs possible. privatenet: 192.168.0.0 - eth0 public: different public ips, bit all in same datacenter - eth1 we are not able to change this. 2 private networks are not possible due datacenter restrictions. we set the...
