ich habe Probleme mit dem IO delay.
Ich habe eine 3TB und 2 6TB Platten mit BTRFS formatiert und nutze um einen Mountpoint zu haben MergerFS.
Wenn ich auf der Kommandozeile etwas kopiere von Platte zu Platte, dann habe ich 95-115MB/sek.
Wenn ich einen Container starte und nutze...
good morning guys, i'm new to the forum and i use proxmox for about 3 years, i'm having a problem after changing my server disks, i only have 3 VMs on it, and after the exchange i noticed that one of them is slow in some tasks , the slowness does not always occur, they are small "chokes" that it...
I have 3 Proxmox hosts, one with version 4.4, another one with version 5.2 and the latest with Proxmox 5.3.
From these 3 hosts, I would expect the 5.3 host to be the most performing taking into account the better hardware. All of the hosts have hardware RAID 10, with the latest (5.3...
3 month ago average IO Delay increased dramatically, about 10 or 15 times. Nothing radically changed in VMs. Hypervisor hardware also the same. I have 17 VM running: (10 with Windows 7,10, Server 2012) and (7 with Linux Ubuntu 18.04).
There are 3 disks also:
all VMs on nvme0n1 (m.2...
When I migrate/restore VM I see that kworker use 99% IO (by iotop). And other VMs on destination node sometimes stuck.
All running VMs on destination node show this exception:
I use HW RAID1. Lvm-thin pools.
Hardware: R540 - Silver 4114
Raid: Perc H730

I am trying to understand what is going on, but unfortunately I cannot find the cause. To keep this issue description short, I made a new installation of Proxmox 5.3.8 using the following hardware:
CPU: Intel Xeon E5-1650v3 - 6c/12t - 3.5GHz
RAM: 128GB DDR4 ECC 2133 MHz
I have a weird situtation tought you could help me
I have a cluster of three nodes running proxmox + ceph.
Ive installed the os (+ceph) on 2 x usb drive as zfs raid1, now I have high I/O wait on the CPU because the usbs are slow.
I added 2 x SAS 15K and I’m thinking if its possible to...
I just bought a new server and install proxmox 5.2-10 but I have a lot of IO delay and don't know how to improve FSYNCS!
Could you help please?
Here are some informations, tell me if you need something else :
Server info :
Intel Xeon E3-1270v6
4c/8t - 3,8GHz /4,2GHz
64Go DDR4 ECC 2400 MHz...
I have been checking having a reccuring problem lately on my proxmox.
Since one week, my proxmox sever start to have some/lot of IO delay like tonight :
the same graphic but in days :
When checking /var/log/syslog the only alert I have that could be cause or a consequence of...
I don´t see the bwlimit option anymore:

sobald mehr als 3 virtuelle Systeme laufen, heben die IO Delay Werte spürbar ab. Folglich reagieren die Systeme immer langsamer.
Solange es sich bei den virtuellen Systemen nur um Linux handelt geht es noch.
Schlimm wird es meistens, wenn zusätzlich ein virtuelles Windows-System läuft...
Today, I realized that since the night between May the 27th and May the 28th, when we rebooted one of our nodes, its disk latency just went nuts. Alas, it's not just its disks, it's also the disks of any VM started on this node. By investigating, I was able to correlate the beginning of...
Today I try to recover VM from achive and get a huge IO delay on PVE node.
Before that, everything was fine.
I noticed the following: when "space reduction due to 4K zero blocks" at end of the recovery report is great enough, I get huge IO delay.
For example, when I recover this arhive...
I am struggling since 4.4-12 to 5.1-36 upgrade (to be fair it's a new deploy) due to terrible I/O performances via iSCSI (but after some testing also NFS seems affected). The problem doesn't always show up, but I have been able to reproduce it in this manner:
VM just booted up with...
I completely wiped out my system and started from nothing after I assumed I made a mistake.
I thought because I mixed SSD and SAS drives in LVM it caused my IO issues.
This time I completely left the SSD drives untouched and installed proxmox on the large SAS raid 5 array on the hw controller...
I am getting very high IO Delay on any kind of a load. It basically stalls all VMs. We are a web host and we have five CloudLinux/cPanel VMs (all with about 100 sites each), A Windows 2016/Plesk VM, and a CentOS7/Sentora VM running. When this happpens all sites stop responding, I get kernel:NMI...
since I started using proxmox, I am having serious issues in "high" (i.e. peak) I/O cases.
Computiation power and memory is not an issue. The system is running on a HW-Managed RAID5 array, alltogether ~8TiB, about 20% used. About 10-15 VMs are running on it with...
I recently got GPU passthrough working on one of my VMs and I'm delighted to say that everything appears to be working as it should, with one minor exception. I'm noticing some serious slowness in the IO/hard disk department. Sometimes the guest machine appears to be fine. Other times...
Fresh install on fresh 1TB RAID 10 array
this image was from restoring a VM from the local HDD (i only have local drives)
that was a < 50GB LZO backup and everything slowed down a LOT, this is a fresh install that i just installed today.. made sure to update everything so its all freshly up...
