Hello, I was wondering it this could just be load on your server? How many VMs / CTs are you currently running? Maybe there is a stuck process if it’s not the load?

This could potentially means that one of your drives is going to fail sooner or later indeed.

Hmm, that's unfortunate. Could you please provide me more details about the CPU specs of the node? And maybe do you have a screenshot of the statistics on the node? Thanks in advance!

Sounds good. I run containers always without swap so you could try to disable this to. However maybe it's better to see if it works for now, if not you could always try to also disable swap for your CTs.

Thanks for the information I lookup real quick but couln't find any issues relating to this model. Since there are no SSD's for the VM host could you try to disable swap on the VM? (vm.swappiness=0) This is what I used to do when we had in the past high IO delay. Maybe this could work but I am...

Hi There, According to your first question; You have 4 VM's running with a configuration of 8GB RAM, 4 cores, 250GB storage each. While your node/host (server) has in total 12 cores (including hyperthreading?) 32GB of RAM installed and 1TB diskspace. The thing here is when you start spin VM's...

Which type Dell Hardware Raid Array to you use?

Good to know. I think in this case the best option you have is not monitor the I/O delay via iostat in order to determine where it is coming from. My guess would be something with the Hardware array after a sync (which could happen after exactly 5 minutes).

Hello, Thank you for sharing the info to! Nice to hear, but be aware of the wear-out (depending what you running on the VM's) this SSD's could wear-out rapidly and also the don't have a good PlP. (Power Lost Protection) but I think in your case this is maybe not the bottleneck. Be aware that...

Hello, I would like to share my experience with Proxmox and consumer/prosumer SSD's. We currently running several servers with also consumer/prosumer SSD's as boot only (not for storing any CT/VM disks). Also we have several servers running with enterprise SSD's used as boot. The thing we see...

Dear Michael2006, Thanks for your reply. Can you provide the disk type you're using, when you had this wear-out issue? Thanks in advanced!

Yesterday we migrated to the new Intel D3 S4510 1.92TB disks and we are good with the IO now. ;) This thread can thus be marked as resolved.

Weird enough... pveperf MX500 root@stb01:~# pveperf /rpool/ CPU BOGOMIPS: 231792.20 REGEX/SECOND: 3000297 HD SIZE: 893.86 GB (rpool) FSYNCS/SECOND: 10971.13 DNS EXT: 16.00 ms DNS INT: 65.45 ms (netbeheer.eu) pveperf S4510 root@stb01:~# pveperf...

Thanks you very much! We now know what to do ;) I let you guys know when we moved out the disks and test with the s4510.

Thanks for your answer! Does the Intel D3-S4510 1.92TB in your opinion fits with proxmox ?

Just tested, same result unfortunately. I searched for a while on the web and so far there are much more people having issues with Proxmox and ZFS IO Delay, so far nobody has a workaround to the high IO delay on a ZFS pool even with DC Intel SSD's? Edit: We see that the IO delay only occurs...

We just tested on Intel D3-S4510 with a plesk environment, and if we test write with: dd if=/dev/zero of=/root/testfile bs=1024M count=1 oflag=direct The speed seems normal within under 2 seconds 1.1Gb copied. But in Proxmox we see a IO delay spike to 45% and then immediatly to 0% is this...

Understandable, budget wise is this not a option for our customer in this current situation unfortunately.

Thank you very much, I understand now, we will plan this in order to achieve this en wipe out the Crucial Disks. One last question and I hope you could give some advice on that, If we are set up a second server which is a HP Proliant DL360 G9 with 128GB DDR4 ECC RAM, 20 cores 2.9Ghz (40 cores...

Hmm I understand, the only thing we host are web / mail en MySQL server VMs, for instance plesk servers and stand alone Linux
