zfs

Hi all, I am looking for some guidance on the clean removal of a node from Proxmox cluster. What I did so far: - Created cluster named 'Test-PVE' - Added three nodes (proxmoxVE01-03) to the cluster - Verified cluster manager status and nodes via 'pvecm status' and 'pvecm nodes' -> all three...

I am trying to use zfs send to duplicate and entire pool between 2 nodes and I am getting very slow results. Any help would be appreciated. Hardware (both nodes identical): HPZ840, Dual Xeon 36 core, 256GB ram Asus M4 with 4x 2TB WD SSN7100 in RaidZ NIC Intel X550T2 10Gbe Testing pool speeds...

Hi, I have two VMs which have cloudinit drives, which are failing to replicate over that drive, when a replication task is created, other VMs with cloudinit drives are replicating over fine but these two aren't. Granted those other VMs replication tasks were created months n months ago. Trying...

Hi there, I am running Proxmox on a dedicated server with OVH, and under high disk load, the whole system seems to be taken out. Sometimes just for a few seconds, sometimes a few minutes, and more often than not completely requiring a hard reset of the system. When this happens, I can't see...

Hello, I installed Proxmox VE using two disks with ZFS RAID1 (mirror) for lab testing From my testing: If I unplug or fail disk 2, the system still works fine and Proxmox is accessible. But if I unplug or fail disk 1, the system will not boot and Proxmox becomes inaccessible, even though disk...

Hey everyone, I'd appreciate some advice on properly partitioning and configuring my Proxmox VM/CT & storage server. I want to make sure I'm following best practices before I start deploying VMs and containers. Here's what I'm working with: Hardware Setup: AMD 3950X with 64GB RAM...

Due to a lot of drive issues I decided to downgrade the size of my ZFS vdev. I currently have 3 12TB drives in ZFS Raid-Z1. I plan to switch to 3 3TB drive ZFS Raid-Z1. I have about 5 containers/vms that I would like to keep. the rest can go. My system doesn't have the sata connections...

I really tried to find an existing thread, but everything I find is either related to the main/boot pool, or adding an encrypted dataset only, so I figured I write down my steps for my own documentation and maybe it'll help someone else out too. This is for when you already have a PVE set up...

Verbatim copy of https://bugzilla.proxmox.com/show_bug.cgi?id=6773 Short: a SUSPENDED ZFS pool is not recognized although all VMs stall and services are practically down. Long: after upgrade to Trixie 13.1 (pve-manager/9.0.6/49c767b70aeb6648 (running kernel: 6.14.11-1-pve)) on 08 Sept. 2025...

Hi all I've just bought a nice new server with a good chunk of RAM in it and installed PVE 9 and I was wondering is there any harm in over sizing the ARC? I know the formula is 4Gb + 1Gb for every TB of RAW storage so for example my server with 20TB of RAW storage the ARC max should be limited...

Hello everyone, I am experiencing an issue with my ZFS pool usage reporting. My ZFS pool "Crucial" is showing 71.69% used (663.64 GB of 925.73 GB). However, this pool only hosts 3 virtual machine disks: VM100: 274.88 GB VM101: 90.19 GB VM102: 90.19 GB This gives a total of 455.26 GB, which is...

Target audience: Beginners There are no secret tips-n-tricks here, just basic knowledge. Precondition you have an intact PVE installation, be it a single computer or a cluster with several nodes; I am using the current 9.x release you have HDDs which may contain old data - that data will get...

Hi folks, I'm going to be building a new Epyc based server this week, and I have some questions concerning ZFS pools under Proxmox. Previously, I've done most ZFS related things with TrueNAS, first virtualized, and now bare-metal. I have two TrueNAS machines that handle all typical NAS duties...

Hi I attached 2 disks to my proxmox node and made a zfs mirror and place 1 lxc on there currently I want to use sanoid to take snapshots - hourly / daily and weekly - which I want to then syncoid to another zfs pool. I am concerned that all of the snaopshot and bookmarks will affect proxmox

I have a Proxmox Server with ZFS (mirror - two disks). After a power outage, i get an error that the pool it was already there. I check /etc/zfs/zpool.cache and it was empty so i run this zpool set cachefile=/etc/zfs/zpool.cache pool After reboot, i get this error message cannot import pool...

Hello everyone, This is my first post on this forum and I am a bit of a noob so I appreciate your patience. So I just upgraded my proxmox server to 9 and I can't boot into the system. It is stuck at busybox (initramfs) and here are some of my outputs: zpool status show all of my pools (rpool...

Proxmox 9.0 Last night my backup job failed with the log: INFO: filesystem type on dumpdir is 'zfs' -using /var/tmp/vzdumptmp417990_104 for temporary files INFO: Starting Backup of VM 104 (lxc) INFO: Backup started at 2025-08-14 21:04:48 INFO: status = running INFO: CT Name: jellyfin INFO...

I upgraded to 9 - and managed to break my zpool imports. There seems to be some kind of error in the cache, but despite removing and recreating the cache, nothing fixes the error and allows the system to boot. I've been able to boot via chroot on the proxmox installer. Anybody have any suggestions?

Upgraded to PVE9 last night. My setup is Pve running on a 500 gb Nvme (ext4) which has about 5 VMs and 3 LXCs. Two (2) of the VMs include Immich and Plex which store data on the ZFS pools. Following the upgrade this is what i've noticed; is there anyone who could provide assistance on this...

Hi I was able to upgrade to PVE9 without issues; I am running 5 VMs (including OPNSense) and 3 LXCs and lost internet connectivity a few hours later. Was unable to see any output or access PVE via the web interface. Had to restart the machine and everything is working fine now. Issue - 1: I...
