Thread starter dva411; Start date Feb 13, 2024; Forums. root@pve01:~# zpool status The Proxmox team works very hard to make sure you are running the best software and getting stable updates and security enhancements, as well as quick enterprise support. Add the second disk using ZFS use it for VMs that don't have a ton of storage and need high performance. What is the correct way in order for proxmox to not use that Because we want to encrypt our root partition (which lives somewhere in /dev/sda3) but not our /boot drive, we need create a separate partition for /boot. First of all our setup is 2 Servers with 2x240GB SSD, 4x6TB HDD, 128GB RAM and 2x Ten Core 2. But I would recommend running openmediavault or something like that inside a privileged LXC and then passthrough a datasets mountpoint from the host to that LXC using bind-mounts. 1. OMV on proxmox storage setup I have just setup a 2 node cluster names ProxmosCluster. There are 2 raid structure on hardware raid, one is raid 1 with 2 disks, the other one is raid 5. After the pool is formed and you’ve created your datasets with the CLI, go to Datacenter > storage > Add > ZFS. In case of a node failure, the data since the last replication will be lost, so it's best to choose a tight enough replication schedule. I am considering adding 2 SSD's into the mix to act as ZFS L2Arc and Zil+Slog. Hi! I’m trying to setup ZFS over iSCSI. Is this because ZFS is thick provisionned? ZFS is thin-provisioned and all datasets and zvols can share the full space. I personally use thin provisioning, which is an option when creating the storage When I setup a ZFS storage on my Proxmox cluster I can only tick "VM disks and Container" I'm partition based as my system is also running from the hard drive as raid partition. Works like a charm. Create a folder to mount external storage under /mnt a. Proxmox is installed in a ZFS raid on two SSDs. I have a ZFS pool and would like to pass a volume or maybe even a filesystem to the omv container, but so far I'm out of luck. I have a setup with 3 nodes. ZFS can do atomic writes if you have a specific usecase in mind since it's a cow filesystem. The VM replication feature of Proxmox VE needs ZFS storage underneath. There Setting Up ZFS Pools for Proxmox Storage. ZFS uses as default store for ACL hidden files on filesystem. ZFS pools are the foundation of storage in ZFS. if you optimize Postgres for ZFS for the task at hand, you will get much better times even with an enterprise SSD without raid0 in ZFS. They all serve a mix of websites for clients that should be served with minimal downtime, and some infrastructure nodes such as Ansible and pfSense, as well as some content management systems. As this seems to be for production use i would not go without a raid. The cluster was created on PVE01 and then PVE03 joined the cluster. Right now have all the runners and images; 120 GB Kingston A400 SSD (3 drives) --> I recently buy not config yet The In this tutorial, you will install Proxmox Virtualization Environment with the OS running on a pair of hard drives in a ZFS RAID array. I don't know enough about ZFS on top of hardware RAID to even make comments here, but I've read on another forum that someone setup their disks on hardware raid, then in Proxmox, created a 1 disk ZFS, and presented that hardware raid "disk" to Proxmox. Tens of thousands of happy customers have a Proxmox subscription. Get IP address and SSH in 6. proxmox-boot-tool format /dev/sdb2 --force - change mine /dev/sdb2 to your new EFI drive's partition. These will be connected to another Server with FC HBA in target mode, running FreeBSD or Linux (not sure yet) with 2 zpools Hi I am very new to proxmox and have the following setup: 2x 60gb ssd enterprise drives in zfs raid 1 where proxmox is installed that shows up as local and local-zfs - here I can create vm's without an issue, the problem of course being there is very little space. It seems I could configure storage on the TNs side so each zvol houses one vm. Prev. 2. In the table you will see "EFI" on your new drive under Usage column. I am sure the space is enough for multiple virtual TrueNAS's, without the data-disks. Setup is simple, 2 SSDs with ZFS mirror for OS and VM data. 3, and which are booted using grub. If I was to setup L2ARC, it is as simple as zpool add -f -o ashift=12 NAS cache /dev/sd* and since it is considered volatile, The Proxmox community has been around for many years and offers Proxmox UI will automatically detects the ZFS and insert it in the ZFS page. Proxmox UI will automatically detects the ZFS and insert it in 500 GB Seagate Barracuda ST500DM009 --> In a ZFS pool "HDD-pool" for images and VM Disk. Configure a ZFS volume in Proxmox. It is totally fine if some or all disks display uefi,grub instead. I currently have a proxmox box and a seperate NAS. This article provides an overview of the dRAID technology and instructions on how to set up a vdev based on dRAID on Proxmox 7. You could limit the size of a dataset by setting a quota. 4 with ZFS, during installation I choosed ashift=12, however after installation, I decided to check the bytes per sector using: fdisk -l /dev/sd[abcd] This gives me: Disk /dev/sda What has not been mentioned yet is that you can use ZFS in combination with HA if you are okay with async replication. Is this possible? I have been looking at tutorials and cannot find one for RAID 0 as most use ZFS for RAID but Proxmox does not offer RAID 0 in the tutorials. We will have both an EFI & boot partition. To add more storage and provide a bit more disk performance. In short, I want to create storage that I will use for data storage and for storing NextCloud files. When I run the command from shell I get ‘kvm: cannot create PID file: Cannot lock pid file’ Anyone an idea how to fix it Also, since Proxmox likes to eat disks whole, I've then used the smallest size 256GB sticks to boot Proxmox and then allocated internal NVMe, SATA and external whatever to Proxmox VM or container storage and backup. I intend to create a separate RAID array (either RAIDZ2 or RAID6) and then use this RAID only as a data storage. My problem is that I want to be able to move my media storage around from VM to VM. If one node if you use virtio or virtio-scsi, you don't need ssd emulation, just enable discard.

Again, ZFS pool in Proxmox, create a vDisk with almost the full pool size, give it to some VM and create the SMB share there. Which can help in replication, which would be faster compare to rsync. Thread starter Valerio Pachera; Start date Feb 20, 2018; Forums. In the above example, we see all three partitions from the three ZFS disks setup for "grub" only. After installation I booted right into the rescue mode and followed this link to a gist with instructions By optimizing settings like atime, implementing SLOG devices, and monitoring SSD health, Proxmox administrators can mitigate some of the challenges associated with using consumer SSDs in ZFS - test various setups for zfs for many days, and watch your graphics (librenms), and document what you setup, and what you have get with this settings(for any bad/good results) including graphics, logs or anything that could be useful in the future (you will forgot many details after one year, and you do not want to waste your time) Hi, this post is part a solution and part of question to developers/community. Now I test the new Directory by uploading a new ISO. Oterwise ask your hosting provider. Disclaimer: Not the most beginner-friendly solution, you might prefer ZFS is killing consumer SSDs really fast (lost 3 in the last 3 monthsand of my 20 SSDs in the homelab that use ZFS are just 4 consumer SSDs). 5. HA is enabled for the VMs, and there are replication jobs that keep the content identical across the ZFSs. You’ll need to identify the disks that you want to use for ZFS Configure a ZFS volume in Proxmox We will start by creating a Disk Pool in Proxmox which will then be added to the available storage. Works fine and the fileserver CT has the full space of Hate to necro the post, but the is the only thing I've found online on configuring ZFS replication between two nodes. I would like to import this pool on my new proxmox box, and The Proxmox community has been around for many years and offers help and support for Proxmox VE, Proxmox Backup Server, and Proxmox Mail Gateway. I added syncoid in pull mode that connects to Proxmox as a specific user with limited rights (through ZFS delegation) to pull new ZFS snapshots. Help with new setup (ZFS) , CPU/Memory Allocation. Zamba LXC Toolbox a script collection to setup LXC containers on Proxmox + ZFS. It should be worth mentioning as well, that after setting up this ZFS pool I started seeing high memory usage on my node. This, because I want to use a development Proxmox that I could take from the office to another remote location, where for some reason I would not have access to a PBS and there will be major changes to the VM. I'm currently struggling to find a decent configuration for a proxmox + omv lxc setup. But which zfs? ZFS ZFS has multi device support for doing raid, ext4 does not. Proxmox does not do anything at all with the SSDs, except of the actual passthrough to the VM. Now, I am plannning to use ZFS (Raidz2:RAID6). My plan was to set up a ZFS storage and share it via network. Hi, I have bought a used host for my windows vms (build teamcity, web and mssql) and debian containers (web, postgres) and can't figure out which storage setup fits best HP DL380 Gen9 2xE5-2690 8x32GB RAM B140i onboard P440ar dedicated (HBA mode) 8xS3710 400GB I switched P440 to hba mode and ZFS Pool inside Proxmox PVEIt is very simple to create and use it. So first disable all raid features in the bios, then wipe those two disks and create a zfs mirror with them. Enable discard and iothread. In all reality ZFS is only really useful if you either have server hardware with tons of extra RAM, or if you are only running a couple VMs & are more concerned with High Availability than with performance, resources, or anything else. Proxmox VE can also be installed on ZFS. Also, keep in mind that a ZFS pool should always have 20% of free space. The target disks must be selected in the Options dialog. Most people just don't know how to proper do hardware or database optimizations. So I added 2x 900gb scsi 15k set up the ZFS datasets on Proxmox itself, mounting them under /pool/data created an unprivileged LXC Ubuntu container accessing the datasets through bind mounts (1 for each dataset) set up the uid and gid mappings for the users/groups that must access the datasets set up Samba in the LXC container the usual Linux way the same datasets I expose with SMB are proxmox-boot-tool format /dev/sdb2 --force - change mine /dev/sdb2 to your new EFI drive's partition. Looks like OMV really wants a block device somewhere in /dev so it can start doing its thing. mountpoint The mount point of the ZFS pool/filesystem. Proxmox VE: Installation and configuration The Proxmox team works very hard to make sure you are running the best software and getting stable updates and security enhancements, as well as Proxmox VE can be installed on ZFS. Now which raid i should select while installing Proxmox VE? I'm close to pick the zfs ones. . Learn how to install and configure ZFS as a file system and root system on Proxmox VE, a Linux-based virtualization platform. The special feature of dRAID are its distributed hot spares. 2 disks What is default layout and settings/features/fstab used by proxmox when installing to run on ZFS? Background - I installed a system with the Debian text installer and then converted Debian to proxmox, now I installed two new SSDs and want to migrate the system to a ZFS mirror, the proxmox documentation about ZFS explains how to create pools etc but does not Set ZFS blocksize parameter. It is recommended by proxmox and other peoples to use ZFS Pools for Storing your VMS ( It gives you more performance and Redundancy ) Setting up HashiCorp Packer with Proxmox Part 2 Connect the drives to Proxmox, create a ZFS pool, install Samba on Proxmox and share the ZFS. My nas holds 3 harddrives which are setup as a zpool with 1 redundant drive. I've made my ZFS pool (under data center / storage) on the proxmox machine and then used it all for the "root disk" on a turnkey fileserver CT. While it is possible to configure zfs pools from within the Proxmox web interface, you have more control if you create it using the command line. My setup is 128gb of ECC RAM. This will discard unused blocks once a week, freeing up space on the underlying ZFS filesystem. more on this configuration below. using ZFS caching isn't ideal for virtual Hello forum, I have setup a ZFS RAID1 proxmox instance with two HDD each 1TB. The nodes are both running proxmox 5. Goal- add a second 2TB Intel NVMe disk as a mirror without having to wipe and re-install I don't really care that much if I have to wipe and rebuild I was interested in this also as also a proxmox noob. So if that's the motive behind the dual drives, it may not be For a typical Proxmox setup using ZFS, it’s often recommended to have at least 16GB of RAM, with 32GB or more ideal, especially if running multiple VMs or containers. yes. For a zvol you change the volsize property using the zfs command and you pass it the ZFS path rpool/swap and not the zd device. More ZFS specific settings can be changed under Advanced Options (see below). Background: I installed Proxmox which did not add swap (which I though was intentional, but swap is recommended). ZFS: a combined file system and logical volume manager with extensive protection against data corruption, various RAID modes, fast and cheap snapshots - among other features. Edit the file /lib/systemd/system/pvestatd. How exactly do you, "Please use the same pool name on both nodes, and configure only one zfs storage using than pool name. With proxmox I will lose the synology active backup for the VM's - but I guess I can replace with a proxmox backup server - to be tested] I love the ZFS over iSCSI creating a seperate Extent for each VM disk. setup the 6 drives as three mirrored vdevs (three raid one's presented as one pool) or setup two raid Z1 vdevs with three disks so you can grow by two or three disks at a time instead of 6. Update time: # dpkg-reconfigure tzdata 7. For example zfs set quota=50G RaidZ/ISO if you want that RaidZ/ISO could only store max 50GB of data. Defaults to /<pool>. Hi everyone, I am building a new Proxmox VE server, and I’m looking for some input on the ideal setup for my hardware and use-case. We think our community is one of the best thanks to people like you! It sounds like zfs is the way to go. I'd reccomend another drive to match your 480GB SSD so you can at least do a mirrored ZFS (redundancy ftw). In summary, ZFS is a powerful and advanced filesystem well-suited for Proxmox. Checking ZFS Health Status. ZFS ZFS Replication: You can easily configure ZFS to replicate data between the two nodes. SLOG and L2ARC to speed up ZFS on Zamba LXC Toolbox a script collection to setup LXC containers on Proxmox + ZFS. These are testing / /backup systems as home. Also, if you someday you find yourself with another disk, you can add it as a mirror to your single-disk ZFS setup, which is nice. zpool status pool: rpool state: ONLINE scan: scrub repaired 0B in 3h58m with 0 errors on Sun Feb 10 04:22:39 To avoid this bottleneck, I decided to use the ZFS functionality that Proxmox already has, and toughen up and learn how to manage ZFS pools from the command line like a real sysadmin. Create the same ZFS pool on each node with the storage config for it. On both nodes, I have created a single ZFS pool to hold my vm. jorzxex nwepo sjxtepx dgdtxp nxg zmd cara hljko gopvhjkxf niook
