zfs

Hi all, I have several problems to replace a HD which is handed over by ProxMox to an OpenMediaVault (VM500) which handles the HDs by zfs. When ProxMox (8.4.19) boots, on the console I get the message: --> Port3: ST12000VN0007-2GS116 S.M.A.R.T Status Bad, Backup and Replace Press...

I'm having an issue and can't get my server to boot back to the prompt. Any reboot gives the error [31.621178] PANIC: zfs: rt={spa=(zfspoolname) vdev_guid=1903510110132383870 ms_id=471 ms_allocatable}: removing nonexistent segment from range tree (offset=76c079f6000 size =300000) I have tried...

Hi all, Currently I am running on PVE 9.1 with native MDADM RAID5(3x8 TB disks) looking into prospects for switching to BTRFS or ZFS but every now and then power goes out. At the moment I got 4 TB used out of ~ 16 TB and despite some issues it works awesome. Anyone got experience with ZFS and...

Hi everyone, I created the Proxmox datastores using ZFS in mirror mode; the disk pairs have the same capacity, and almost all the virtual machines I have running on them were migrated from ESXi. I have ZFS replication enabled between two nodes. I was trying to figure out if it’s possible to...

I'm not sure if this is a new problem as I havent tried to remove a CT for some while. But today I wanted to remove a few CTs which are running on a NVME ZFS and all result in "TASK ERROR: zfs error: cannot destroy 'NVME-Pool/subvol-121-disk-0': dataset is busy" Similar behavior on that...

When ProxMox (8.4.19) boots, the following messages are shown on console: Found volume group "svProxHD" using media type lmv2 Found volume group "pve" using media type lmv2 3 logical volume(s) in volume group "svProxHD" now active 6 logical volume(s) in volume group "pve" now active...

Hi everyone :) I've created a 200 TB zpool "tank" on the commandline. Works fine and is reboot-safe. However, it does not show up in the proxmox web-UI (in the left "Datacenter"-tree view). Another zpool "ma1" I've created with the web-UI, shows up nicely. Where does pve UI store which pools...

Hello everyone, first time poster here. I have a ZFS pool that has 878GB Free, with 1.22TB Allocated. I have been trying my best to figure out how to release that free space into the pool itself. Any help would be appreciated, Ill post the details below. I have turned on Autoexpand for it as...

Hello everyone. Within my Proxmox setup i am at a point of questioning the way i have completed. I would like some guidance on the issues and the steps i have taken and how to move within this state to the "correct" / "desired" stability. specifically the zfs share between my ct (ubuntu) lxc...

I have 3 node proxmox cluster with zfs storage and want to setup replication jobs but I have around 30 LXCs and can only setup one by one. I have LXCs in all 3 nodes and I want all LXCs replicated to all nodes. Is there a way of doing this without having to manually add an entry to every node...

Before I waste a bunch of time on this... has anybody either succeeded in doing this in an LXC, or ("expertly") concluded that zfs snapshot automation must be done in the PVE host? I too of course would love to see Proxmox add a feature for dataset snapshot automation ( every M minutes, every H...

Hello, I am looking for guidance on the safest next step for a single-node Proxmox VE host with a mirrored ZFS pool. At first my priority was to preserve data and avoid destructive recovery. That is still preferred. However, at this point I am also open to destructive steps if necessary, as...

The title sums it up, more or less. I'm relatively new to ProxMox and self-hosting in general. I basically want to share NextCloud folders with other LXCs, and think I ran into a case of trying to figure out too many things all at once, and thought I'd ask for advice, just to be safe. I'm...

Ich bin inzwischen am Verzweifeln. Nachdem der Mainboardtausch durch eine Neuinstallation Proxmox wieder zum Leben erweckte, habe ich scheinbar nicht nur mit dem Mainboard ins Klo gegriffen. Mein gebrauchter ASR 8405 verabschiedete sich so alle 3-5 Tage mit SCSI hang...? Nachdem ich wohl alle...

The different names for disks may lead to confusion. I show some different names to specify the "right" device. Why is this important? Well..., the obvious thing is that “zpool create” will destroy the old content. You will lose any data stored on it. And the “classic” names like “sda” may...

I need some help understanding the alert I received today. I'll give some background, but I'll hide it as a spoiler in case the extra detail isn't relevant. Today I received the following alert: DegradedArray event detected on md device /dev/md126 The /proc/mdstat file currently contains the...

Hi Proxmox community, I am currently running a 3 nodes cluster and all my VMs disks are stored on NFS shares provided by another physical server. As that NFS server is a SPOF, I would like to replicate the VM and their disks on my third node : pve1 and pve2 have access to the nfs shares named...

Hi, I have a cluster of 4 nodes which is all up-to-date (9.1.6), but I still see zfsutils-linux as upgradable but not upgraded (even is nothing is on hold, from APT's perspective). # apt list --upgradable zfsutils-linux/stable 2.4.0-pve1 amd64 [upgradable from: 2.3.4-pve1] Notice: There are 3...

Greetings proxmox team Would you be able to check https://github.com/openzfs/zfs/issues/15918 please Basically upon docker container OOM, zfs sometimes crash/panicks and computer must be rebooted to fully fix a problem. Thank you in advance. Excerpt: [244742.755626] Memory cgroup out of...

Dear all, I am running PVE in a what i consider being a rather typical "IT nerd" setup, a 3-node-Cluster on consumer hardware. Private use only. 2 nodes are built identically: AMD 3200G (2C/4T) APU, 32GB DDR4 RAM, M2 NVMe for OS, 2x4TB HDD for storage (connected to SATA onboard), GbE NIC 1...
