Hi, proxmox 8.1.3. I've set atime off in my pool zfs get all rpool | grep 'time' rpool atime off local rpool relatime on default I've the problem that if I add a mount point (mp0) to a LXC container, I can't specify in the...

Hi, I've a U2 Kingston DC1000M 1.92TB as secondary storage (ZFS formatted) that I use "just in case I need speed". When installed it was very fast as expected (es read performance 1454.99 MB/sec). i.e. root@proxmm01:~# hdparm -tT /dev/nvme0n1 /dev/nvme0n1: Timing cached reads: 20680 MB in...

Forgive my ignorance in "high level hardware" but I've only experience with my "self made" Proxmox server at home and I've been asked by a friend that runs a small IT business about a Proxmox server for his customers. My idea is that I will boot from 2 ZFS raid1 small DC Sata SSD, have a VM...

Hi, my home proxmox "server" is headless and does not have any IPMI console. I need to boot it with previous kernel, but if I try to remove the last one as suggested in this thread https://forum.proxmox.com/threads/changing-selected-kernel-for-boot-systemd-boot-on-headless-pve-host.59593/ it...

Hi, I've a vm (Kubuntu 19.04) that I use to test Freecad and that I turn on when needed. I've no need of "mitigations" about CPU flaws or whatever, I just need more performance I can. In the vm I've disabled all CPU flags (-md-clear;-pcid;-spec-ctrl;-ssbd;-ibpb;-virt-ssbd;-amd-ssbd;-amd-no-ssb)...

In a 3 node cluster, 2 with drbd9 storage and one for quorum, I've 4-5 times a day corosync problems like those below. Sometime I enter the web GUI and I see the other nodes in red, pvecm status says is everything ok, but if I dare run the command i.e. "qm list" it hangs and there is no way to...

Hi, I'm testing Proxmox 5 (latest updates) and it's Ceph (luminous). I've 3 VM with Proxmox installed, 2 as storage with 32GB virtual disk each, and the 3° only with local storage as 3° monitor. I've followed instructions on https://pve.proxmox.com/wiki/Ceph_Server and some googling around I've...

I've a new server where I've installed an Areca RAID controller 1883i, 4 x 1TB RAID10 WD Enterprise Gold and 2 x 2TB RAID1 WD Enterprise Gold. The controller has a "supercap" and Write Back cache enabled, raid has been initialized this night. With Proxmox 4 the same controller with 4x500GB...

I've a 3 node cluster (but only 2 node storage) with enterprise repo and drbdmanage 0.91-1, so I think I'd better upgrade now (also hoping 0.97.3-1 will fix some issues about calculated free space) since the license change and waiting to things to clarify (and in the future avoid the...

Hi, I've a Kubuntu 16.04 vm and spice works fine (I've "Use tablet for pointer" Yes, "Qemu agent" Yes, Display "Spice (qlx)" and in the guest I've installed spice-vdagent). But when I try to set spice on Windows 10 pro (or even Win7), the mouse keeps being grabbed and is not precise/does not...

Hi, the above controller looks very interesting, especially with the Flash Base Module as "permanent" BBU and the possibility to be configured from LAN. In the wiki I've found that the line ARC-1210, ARC-1212 and ARC-1222 works but nothing about the above one. Anyone has experience? Works fine...

Hi, prox 4.1 (enterprise), 3 node cluster with 2 node with drbd9 thin provisioned storage (package thin-provisioning-tools installed in both nodes). I've created a 400GB second disk on node1, and since is empty at the moment, I see "data% 0.05" with lvs. But if I go on the second node, I see...

Hi, I've prox 4.1 (enterprise repo) and drbd9 cluster with thin provisioning enabled. I've seen that if I create a VM in drbd9 storage is correctly thin provisioned, but if I restore the VM then 100% (almost) of the space is alloccated. i.e. I've backedup VM 108 and restored as VM 999, and lvs...

Hi, I tested with a VM (qcow2 image file format) and took at snapshot at "stage 0" before trying to install paravirt (virtio) drivers, so disk was IDE and not, after snapshot, is Virtio. Since everything works fine and the snapshot is no more needed, I tried to delete it from GUI, but got the...

Hi, I've 2 nodes with drbd9 storage in a 3 node cluster, linked with a cross cable 10GB/s on nic card. I've noticed that if I disconnect the cable, and create a VM in one node, when I re-plug the cable the new "resource", i.e. "vm-106-disk-1", it's not replicated. drbdsetup status shows it only...

Hi, I'm newbie of DRBD9 and I'm using with Proxmox 4.1, storage on 2 nodes out of 3. I would like to follow the "optimizing performance" tests here http://drbd.linbit.com/users-guide-9.0/p-performance.html. Instead of sacrify a VM disk (i.e. TEST_RESOURCE=vm-100-disk-1), I would love to be able...

Hi, I've a i5 4590 CPU, 16GB ram, 2x1TB velociraptor as Raid1, a Intel 3710 200GB as zil (16GB) and L2ARC (110GB). Arc RAM is limited to 4GB since I've not too much. When I start a VM, the server load skyrockets to > 30-40, I've 3 VMs and I had to start one after the other, because if they start...

Hi, I want to save CPU cycles and disable KSM, also because I've VMs that are all different. I've tried: /etc/default/ksmtuned and put START=no reboot, but no luck Then I also added to /etc/ksmtuned.conf the parameter KSM_ENABLED=0 but I see it's used (in the summary of GUI or with cat...

Hi, as far as I understand drbd9 is over lvm, and I have 2 SSD disks on each server, that I need to "sum" to have their total capacity. I will have an Adaptec 6805e raid controller. The question is: is better create a raid0 with sdb+sdc at controller level, or create two separate raid0 disks...
