I brought and installed https://www.pbtech.co.nz/product/HDDSAM883119/Samsung-PM883-Series-19TB-25in-V4-TLC-V-NAND-Enter Moved all my VMs, went from 15%-40% IO load when cpu was less than 15%... with same load now io is <1%. Peak for last hour or so was 1.7%.... I was having all sorts of issues...

Im happy to spend money.. but would be unhappy to buy something that doesnt fix my issue. Would those samsung fit the bill? I presume I can extend two more drives in the future if I get low on VM space? if I did get another two drives in the future... do I need to rebuild the array? or I can...

I would like some advice on SSD for VMs. Im thinking about buying a couple of these: https://www.pbtech.co.nz/product/HDDSAM883119/Samsung-PM883-Series-19TB-25in-V4-TLC-V-NAND-Enter Would these be okay? or if not what would you suggest.... this is for a home lab and its already out of control...

its ashift=12. I might get another drive and test different ashifts until I find the best performance, then build another zfs array. Then get two better ssd running in mirror for VM disks... and use 4x4tb for meta array. Thanks so much for the help here... its hard when you only know enough...

Thanks so much for the response! Its probably way to late to return them, so im keen at this point to get them in the best shape I can. How do I check what ashift I set? I suspect I left it as the default of 12. ( couldnt find anywhere is proxmox UI, or any zpool command that returns it )...

Samsung 870 ssd: https://www.pbtech.co.nz/product/HDDSAM60330/Samsung-870-QVO-MZ-77Q4T0BW-4TB-Samsung-V-NAND-SAT?qr=GShopping&gclid=CjwKCAjwuvmHBhAxEiwAWAYj-PkAtWD48899ejvR6B_HT0CEG09d6Ci-9Suz1A7Qp1LqEbh3R0Mx7xoCfKcQAvD_BwE At the moment drives are broken into two groups. 1 disk zfs and next...

Hi, I have a dell r910: 2 x Intel E7-4860 10core 20 thread 256 gig ram Dell H200 HBA controller (factory firmware) 3 x Samsung 4TB SSD. I am getting abysmal disk performance, struggling to get past 70-100MBps Disks are capable of 500+ I would have thought 300+MBps should be achievable. No...

Still no random restarts! I backed up my partners phone same way. Still no restarts. Would have restarted atleast once. Looks like for what ever reason smb was the issue or atleast part of it.

SOLVED or at least RESOLVED!!! Okay the random restarts have happened a few times over the last year or so, but were VERY infrequent. But in last 2 weeks was happening every 4 hours or so. But I think I have figure out what was wrong, no idea why this would cause proxmox host to restart. (bios...

Hi, thanks for the response! Logs from 730 to 830 are attached... I think it reset around 750ish... attached. proxmox-ve: 6.4-1 (running kernel: 5.4.124-1-pve) pve-manager: 6.4-13 (running version: 6.4-13/9f411e79) pve-kernel-5.4: 6.4-4 pve-kernel-helper: 6.4-4 pve-kernel-5.4.124-1-pve...

I have a Dell r910 3x4tb ssd data 1x500g rust for proxmox os 256g ram 2x10core intell I'm getting random restarts.. probably between once a day to 4 times a day. I have tested ram, was stable for a year prior. I feel like it might be related to the last few proxmox updates but I could be wrong...

This is my setup: dell r910 256gig ram 8x2TB smr rubbish 1x4TB ssd Dell h200 HBA card running dell firmware LSI SAS9200-16e NetApp DS4246 Orginally with IOM3 but upgraded to IOM6. h200 card works fine and all drives are detected and performances is what I expected. (apart from SMR dives are a...

From research I have done the card have in dell can be flashed to hba. Ideally want to have equivalent to raid 6. So I presume that's zfs raid z2. From internet calculators I would require 3 drives min. Is that correct? Also if I later wanted to continue adding drives can I extend the raid...

I have used vmware for years on an old dell 2950 and dell r710 all for personal use. I have run out of space so decided I would like to give proxmox a crack. I have brought another dell r710. And would like that start with one drive and add more drives over time. I would like to try zfs. Is...
