Hi All, I just received a HGST SN260 3.84T enterprise NVME to host VMs within Proxmox. How do I connect it to Proxmox? What would you recommend? A directory mount or LVM-THIN or something else?? What's your favourite? thanks

Hi, I am unable to take a backup of my pfSense VM. About 50% and it throughs the error: INFO: starting new backup job: vzdump 100 --storage backup --compress zstd --notes-template '{{guestname}} deploy to local-lvm' --remove 0 --node pve --mode snapshot INFO: Starting Backup of VM 100 (qemu)...

Hi, I am trying to download Nvidia vgpu drivers. There are quite a few available for different Linux KVM versions. How to find out KVM version for proxmox so that I could download the right versions for my proxmox? Thanks

we do but I prefer VMs (depending on your workload) or docker from a security stand point.

You can use mini cloud images (available both for Ubuntu and Rocky) as vm-templates in the proxmox and spin them up whenever you like. The best thing is whenever you will spin up a new VM off of it, it will be updated to the latest version

so what you guys are volblocksize for ZVOL passed to Proxmox using iSCSI to create VMs on? Do you guys use NFS for it? If yes then what's the ZFS dataset record size you're using for it? thanks

Hi, I am creating z ZVOL to pass it as an iSCSI device to proxmox so that I could create windows/linux VMs on it. As we know that ZVOL volblocksize (if you get it wrong) can cause padding overheads as well as performance hits! I know, if you wish to run a VM with EXT4 or NTFS, It doesn't...

Hi, last couple of questions: I want to run Windows VMs via iSCSI on proxmox, would you recommend 4K block size since NTFS writes with 4K? Ubuntu using ext4 will also write with 4K chunks so a volblocksize of 4 would also work better? I know VMware (VDI) is typically using around 24-32K but...

I have SEAGATE ST800FM0053 SSD drives. It's data sheet states: User-selectable logical block size (512, 520, 524, 528, 4096, 4160, 4192, or 4224 bytes per logical block) But when I do: root@truenas[~]# diskinfo -v da9 da9 512 # sectorsize 800166076416...

Finally, my quest is over! I am making a YouTube video, I will mention your name :) Thanks for helping me.

yup, super clear on this by now :) This was calculated using the formula: (TotalNumberOfDrives - ParityDrives) * DiskSize * 0.8 `zvol` datasets as we already know have extra padding + parity loss on top of actual useable space. So I calculate the total useable space as normal using your above...

Thank you for clarification but then your numbers are still not matching up :(. I am loosing my hairs lolo_O For example: In this spreadsheet that I created. usable space @ 100% datasets column "i" is showing what you already calculated except for one cell. So I am not bothered about that. But...

This is awesome!! Thank you so much for explaining it. However, it's not tallying up what we already discussed previously? You mentioned that there was no `padding loss` if you had `5x 800 GB raidz1 @ 32K volblocksize`. According to the spreadsheet, Column C (because the total number of disks...

Sorry for being a pain but how do you work out which part is parity and which part is padding?? Here is the formula for example: =((CEILING($A4+$A$3*FLOOR(($A4+B$3-$A$3-1)/(B$3-$A$3)),2))/$A4-1)/((CEILING($A4+$A$3*FLOOR(($A4+B$3-$A$3-1)/(B$3-$A$3)),2))/$A4) What baffling me is that the...

Hi after a whole year again :) I am not sure if you're still around helping people but I am trying to recreate your numbers using a spreadsheet. I do not understand (now) how you were able to separate out parity from padding from the spreadsheet? Lastly, how do you come up with 8K random write...

that's exactly what I needed to know. Cheers mate

thanks, I can see it offers options such as swapsize, maxroot, minfree, maxvz but I have no clue where to adjust local and local-lvm?? no idea what the listed options are for anyway

Hi, I have a 1TB SSD. If I use the default installation using the whole drive then it assigns 100GB to local partition, where I could only upload the ISO images and container templates. And the second partition local-lvm is the remaining 800GB for VMs. I think 100GB for ISO images it too much...

Hi, My Cisco Layer 2 managed switch with default VLAN1 = 192.168.1.254 My proxmox static IP = 192.168.1.5 with default gateway 192.168.1.254 My server iDRAC static IP = 192.168.1.245 My laptop connected to Cisco switch via Ethernet = 192.168.1.12 with default gateway 192.168.1.254 My switch...

You were right, I could do it after installation. Since my one NIC was on the "main network" and if you want to create LACP for this "main network", you need to have access to the proxmox via iDRAC/IPMI or similar means because you will loose connectivity during the process via the IP interface...
