@Alwin - I actually did this, but my system freeze and needed a reboot to be able to login again.. echo 65536 > /proc/sys/fs/file-max

@mira is it ok to add another pool with SSDs? the current set up that I have is intel with HDDs and the additional machine that I will add has amd with it and SSDs.

@mira - Ok thx for answering my question.

I have an existing proxmox with valid subscription install on a intel machine, 2 host 3 for cluster and 1 for managing everything. my question is can I add another host using an amd? will there be any problem?

@Alwin how can I do it permanently? right now when I do ulimit I only see 1024 and I want to double this so I wont have this problem with my vm/ct I was checking this thread: https://forum.proxmox.com/threads/unable-to-create-new-inotify-object-too-many-open-files-at-usr-share-perl5.23700/

I was trying to increase my fs.inotify.max_user_instances with this sysctl fs.inotify.max_user_instances=2048 sysctl -p but I still end up with 1024 when I do ulimit -n I run pvedaemon restart but it doesnt do anything. what am I missing here? the reason why I want try to increase this...

@RokaKen - will you guide me on how to do this step by step? like what manager daemon to restart which to do first etc.

according to the Ubuntu wiki, there's no kernel patch for `CVE-2019-11479` -- which is the least serious vulnerability. https://wiki.ubuntu.com/SecurityTeam/KnowledgeBase/SACKPanic if I have a container with ubuntu OS in it how proxmox protects us and how each of the three CVE numbers (for...

@RokaKen - I don't know if ceph would even let me. In the beginning when I set 1024 for 15 OSD, it wouldn't let me, with the error coming up saying too many PG. That is why it is currently set to 512. I don't think it will allow me to expand to 1024 before adding those OSDs. This was with...

we are in the process of adding 3 more nodes, 2 for ceph and 1 compute. We are adding 2 new ceph nodes with a combine total of 10 new OSD. is it Ok to add all 10 at the same time, then increase the pg after adding all of them? and if it is possible to do what if it reports too few pg during...

just as I thought. thank you for the answer. will share this to my team gladly.

is there a command like pct enter veid that will let you enter a VM's?

Do we need to apply patches for each VM and container on our system? I'm running pve-kernel-4.15.18-16-pve on PVE Manager Version pve-manager/5.4-6

is there a command that we can use to run apt update or yum update on all the containers and kvm? I mean to run it in all kvm or container in just 1 command line.

is there a way to get the microcode without subscription? cat /sys/devices/system/cpu/vulnerabilities/mds Vulnerable: Clear CPU buffers attempted, no microcode; SMT disabled cat /sys/devices/system/cpu/vulnerabilities/* Mitigation: PTE Inversion; VMX: conditional cache flushes, SMT...

I have this same problema as well, as I check there is no file on that folder "/etc/pve/nodes/proxmox2/qemu-server/" system is not allowing you to recreate or put a copy of the conf file on that folder. Thus, anyone has this problem and solution to this?

I set up a proxmox with virtual environment 5.2-1 when I created a VM with Freebsd11.2 in it and setup load balancing. I notice that after several hours the vm is unresponsive, but console if functioning, but can't ping the VM from a remote terminal. CPU usage is at 46% RAM usage of 7.5GB of...
