i/o delay

Hello, my proxmox node has a very high I/O Disk usage, when I check there is a road PID as shown below. I don't know what service this is and what it is for, can anyone help?

I have always had the problem with repeatedly occurring IO delay increases up to 60% and more during heavy hard disk activity. One of my LXCs is an SMB server and when I move large data back and forth over a long period of time, the problem usually occurs. My specs are as follows: 12 x AMD...

Hi, I'm a new Proxmox user. I've built a small lab to evaluate PVE and PBS, with the intention of replace out Hyper-V infrastructure (90 VMs in 3 sites, many in replica). We got two Dell R640 servers for PVE and another for PBS. For this testing purpose we are using 4x WD Blue 1TB SSDs (model...

Hi, I have a 7.2-5 host that every morning at 6:12 has a very high I/O wait. Is there something that PVE does at that precise hour? Like a a cron or something? Thanks

Hi, I'm facing high a strangely high I/O delay. I have 3 times A Dell Poweredge 720XD with (almost) the same configuration. The main specs are that are the same over all three servers are: - 26x 500gb SSDs in a ZFS pool (RaidZ3) ashift 12 with a block size of 256K - 380GB of ram - Dell Perc...

Yesterday such a story happened. There are I/O latencies. Didn't install anything. Drives Samsung SSD EVO Plus 250 Gb, SSD 870 QVO 4Tb, RAM 32 Gb, 4*Intel Core i5-6500. S.M.A.R.T SSDs are good. What is the reason and how to fix it. This may have happened after a Proxmox update.

Hi ! Using diskspd (https://github.com/microsoft/diskspd) from Microsoft, we have benchmark disk speed on a Windows Server 2022 VM, hosted on a proxmox host - of course -, alone. [...] Total IO thread | bytes | I/Os | MiB/s | I/O per s | AvgLat | LatStdDev | file...

Hi, After reading many threads, I decided to open one to try to solve a performance problem that only affects Linux VMs. I have a Proxmox VE 6.5-5 installed on Dell R720 with 2 Xeon E5-2660 v2 2.20GHz, 128 GB RAM and RAID controller PERC H710 Mini (integrated). RAID1 volume for the system and...

Hi there, Disclaimer: I have never had any interaction with a server virtualization management platform and I just wanted a cool software I could use to run multiple VMs, I know nothing about what a ZFS or LVM drive is, I/O delay... etc. I just have experience working with host OS like Ubuntu...

Hello, We migrate old three server on proxmox 5.2 to three new server EG-32 on OVH (Serveur EG-32 - Xeon E3-1270v6 - 32GB - SoftRaid 2x4To) with proxmox 6.2. In december, we migrate all VM on new servers, since, we face on low FSYNCS/SECOND and high IO delay, we don't have any issue on old...

Hi, I have a Proxmox standalone installation and have high I/O when working in any instance running in raid ssd. proxmox-ve: 6.1-2 (running kernel: 5.0.21-1-pve) pve-manager: 6.1-3 (running version: 6.1-3/37248ce6) pve-kernel-5.3: 6.0-12 pve-kernel-helper: 6.0-12 pve-kernel-5.0: 6.0-11...

Hi, Little introduction: I had a big problem of heaving big I/O delay and error in file contents inside VM's on my ovh(provider) server a few months ago after an error of consistency from my mdadm raid. So I had to completely restore all my VM's to have my setup back running. Since this event...
