IIsThisThingOn replied to the thread [PVE 9/ZFS-Based VM/LXC Storage] Why Shouldn't I Disable Swap Inside Linux VMs?.Same here. How else could I speed up reads with ARC? ;)

Like.
I tried setting the ARC limit at runtime. However, arc_summary showed no change. Further research reveals that this is expected behavior — zfs_arc_max can technically be changed at runtime, but the internal value arc_c_max that actually... -
Hi, Did you check /etc/hosts on each host? Sometime there is a stale entry that causes lots of pain. -
Ppsalkiewicz replied to the thread [SOLVED] SSH AllowTcpForwarding set to no automatically?.Hi, PMG doesn't touch sshd_config by itself. In this case I suspect 2 possible ways it could have happened: Ansible hardening role — Roles like dev-sec.ssh-hardening (or similar CIS/STIG-based hardening playbooks) explicitly set...

Hi @ all! Good news, we've re-opened the creation of free PBS datastores! You can order your datastore via https://www.tuxis.nl/en/proxmox-backup-server/ Performance has noticeably been improved thanks to the fixes that Proxmox-devs wrote for...

so yes :) l2arc almost never yields useful results. you're better off just using the drive seperately. More to the point- what is your usecase? in a homelab, its common that your bulk storage can be slow without any real impact. put your...

UdoB replied to the thread [PVE 9/ZFS-Based VM/LXC Storage] Why Shouldn't I Disable Swap Inside Linux VMs?.Correct. That's the reason I didn't test it myself, yet. Please do not hesitate to tell us you findings :-) Fortunately my professional cluster has more physical Ram than it needs. And for my homelab I bought some MiniPC with 128 GiB Ram just...

BBoss replied to the thread [SOLVED] /dev/centos/root does not exist after migrating CentOS7 from vmware to proxmox VE.Thanks for following up. I've tried so many things , so I'm not sure anymore. I think I focused on the reply from mmcarn as it allowed me to boot up the qcow2 image which I couldn't before plus it was more recent than the second comment -...

I didn't but will definitevly change this asap ;) One should take into account that for zswap you always need physical swap as backing device. For example if you use the defaults of PVEs installer for ZFS you will endup without space for a...

Edit : UdoB link is less complicated. I use this script https://github.com/mkorthof/ipset-country on a host customize the code to keep ipdeny.com download/update and ipset generation/update Remove firewall/rules parts Then use the "ipset"...

Dd.oishi replied to the thread Virtual machine freezes with IO error.Are there any errors in `journalctl` or `dmesg`? You can gather the VM configuration/status and the storage status with the following commands: qm status $VMID --verbose qm config $VMID qm showcmd $VMID --pretty pvesm status

Where does the expected performance come from? Is it from the manufacturer and in an unrealistic perfect (sequential) scenario? RaidZ1 write is never more than a single drives performance. RaidZ1 is also not a good fit for VMs due to the low...

RRaid007 replied to the thread KVM processes in SWAP despite 35-55 GiB free RAM – Proxmox + ZFS.Since my root filesystem is on ZFS, there is no way to change the ARC limit at runtime. Or is there any way? The only option is to update /etc/modprobe.d/zfs.conf and run update-initramfs -u to rebuild the initramfs. After a reboot the new...

MMike_Scholes replied to the thread Migrating Servers/Fresh Installs - Sanity Check.I have a production system in work with 50TBs of backup. I also have a home lab with 1TB on Wasabi but it isn't really a lab as the data/VMs are critical hence multiple backups. I am very strong on verifying/testing backups, I normally stick to...

Dd.oishi replied to the thread KVM processes in SWAP despite 35-55 GiB free RAM – Proxmox + ZFS.vm.swappiness=1 does not disable swap entirely; it only makes the kernel less aggressive about using it. Also, even when there is still some free RAM available, pages that have not been used for a long time can still be swapped out...
