you need to disable memory hotplug if you don't have udev rules or kernel option to activate dynamic memory modules.

yes, I'm working on it ^_^ . (Currently working to add qcow2 external snapshot for shared lvm too for san array) For internal snasphot, this is by design I think, the iops are freezed until the snasphot is 100% removed.

proxmox firewall ?

if you have only 1 pool for each kind of disk, set target ratio to "1.0"

seem that you have enabled memory hotplug ? see: https://pve.proxmox.com/wiki/Hotplug_(qemu_disk,nic,cpu,memory)

I don't use it anymore (have migrated all my production to ceph since 10years), it shouldn't be too difficult to adapt, the proxmox side don't have changed too much. (but yes, I need to be updated) Not sure about netapp api side.

you just need to add your juniper switch ips in evpn peer list in the evpn controller config. That's all. ^_^

I really don't have any experience with junos syntax. you need to create symetric routing evpn config: https://www.juniper.net/documentation/us/en/software/junos/evpn-vxlan/topics/topic-map/evpn-sym-t2-routing-ov.html#concept_sym-t2-evpn-vxlan-ov__section_sym-routing-model Basically, you'll...

do you have " source /etc/network/interfaces.d/* " in your /etc/network/interface ? what is the content of /etc/network/interfaces.d/sdn ? you can also have details with "ifquery -c -a"

A third way, if you have a bigger deployment, is to have switch/routers supported evpn. Personnaly, I'm using my arista switch as evpn exit-nodes. The current proxmox exit-node feature is really here for small setups where users don't have a router supporting evpn. About vyos, it should be...

pmxcfs use sync writes (because all nodes need to be synced in case of of power failure), so if you want to avoid write amplification (as a 512bit write will rewrite a full ssd nand), you should really use ssd or nvme with a PLP/supercapacitor. like...

ok thanks ! works fine without lvm in my tests, so no need to use lvmlockd, vgscan,.and all other lvm stuff. About performance, I have compared with ocfs2, and it's really night and day with 4k direct write when the file is not preallocated. (i'm around 20000iops on ocfs2 and 200 iops on...

use differents vlan (vmbr0.X), with differents mtu. (but keep vmbr0 at mtu 9000). This is the only way.

Another question about write performance, I have done some test with fio, and I have abymissal results when the vm disk file is not preallocated. preallocated: I got around 20000iops 4k randwrite, 3GB/S write 4M. (This is almost the same than my physical disk without gfs2) but when the disk...

@Glowsome Hi, sorry to bump this old thread, but I'm currently evaluating gfs2 vs ocfs 2 vs qcow2 on top of lvm. for gfs2, I see in redhat documentation that it's possible to use gfs2 without lvm. (redhat don't support it, but it's technically possible, and for example, xenserver support it...

do you have created 2 differents crush rules for your hdd && nvme ?

then you need to manage remote sync scheduling daemon, passthrough tapes devices, manage other jobs (garbage collection,verification), manage ssl certificates (certbot,...). so you'll have a docker compose at minimum with multiple dockers containers. or you can simply do "apt install...

NetworkManager ???? proxmox don't install or use network manager.

don't use ls to see real used size, it'll always display the "virtual" max size. try: "du -sh file.qcow2"

if in pfense vm, you are already using 1interface in each vnet, you don't need to declare vlan on pfsense, as it's already done on proxmox (or you'll have double tag vlan). you could use vlan tag on pfsense, if you have a lot of vlans, and you want to use only 1 interface on your pfsense vm...
