zfs

I had proxmox running on a zima blade, with two HDD on RAID1 (zfs in proxmox). It stopped working and the pool disappeared. I tried to check if either of the drives could be read for the data on my pc , but it turns out, both drives have failed (it spins but doesn't get detected by the system)...

Hello all, we are configuring a Dell server for ProxMox with ZFS (no Ceph), and I wonder what I should select in terms of Controller. Prefix: I know that ZFS is not compatible with HW RAID, and we do not want to do ZFS with HW RAID. However, on one hand, we also have loads which we want to put...

Hello all, I'm sorry if this was discussed previously, just the search terms ZFS, storage, rpool didn't lead me to the info I am looking for. My past experience is using LXC and incus separately, so perhaps I am misunderstanding how terms I believe to know are used in proxmox. I have a PVE on...

Does PBS actually make use of atime? Or is it just inherited because of ZFS upstream? TrueNAS disables atime by default for performance reasons.

2 nodes, 3rd node does not have access to ZPool, it is just a tiebreaker node for quorum. No snapshotting, backups are handled by Veeam to their own hardware (in other words, no backups in the web-interface of ProxMox). Everything migrated from a HyperV computer, where the 7TB was...

Hallo zusammen, ich verwende PBS 3.4.6, der Backup-Pool ist ein raidz2-Pool bestehend aus acht Festplatten (nicht ganz das empfohlene Setup, es erfüllt aber seinen Zweck und spielt für das Problem eher eine untergeordnete Rolle). Nach einem Reboot mit Kernel 6.8.12-15-pve wurde dieser...

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...
