zfs

Since proxmox upgraded to zfs 2.3.4 I'm having problems with accessing snapshots, it causes kernel panics, making the access hang indefinitely. Part of my backup strategy is automated backups for container snapshots, but this is broken by this ZFS bug. The fix...

Yesterday I updated Proxmox from 8 to 9. Last night I encauntered errors backing up one of my Containers to a Proxmox Backup Server Error Message: NFO: starting new backup job: vzdump 101 --all 0 --prune-backups 'keep-daily=7,keep-monthly=12,keep-weekly=4,keep-yearly=999' --mode snapshot...

Ich habe gestern Proxmox von 8 auf 9 upgedatet, heute in der Nacht hat dann bei einem Container das Backup nicht mehr funktioniert Fehlermeldung: INFO: starting new backup job: vzdump 101 --all 0 --prune-backups 'keep-daily=7,keep-monthly=12,keep-weekly=4,keep-yearly=999' --mode snapshot...

Hi All, Just bought 2 Seagate Exos X16 10TB SAS drives for my home server running through an LSI 9300 16i HBA. I flashed the correct firmware onto the 9300, as I want to create a ZFS pool and need IT mode. It seems to be working correctly, it is detected in proxmox and I can map the resource...

Hi, I'm new to both PBS and ZFS and I ordered an M720Q (Core i3-8100T, 16GB DDR4, 1 NVME, 1 SATA SSDs) tiny computer off eBAY planning to use it to back up my Proxmox VE as well as a couple of laptops and desktops. But as I've searched the web and gone back and forth with Gemini and Grok I'm...

I'm quite the Linux amateur so please don't expect too much from me. I recently ordered a new motherboard to move my server setup to because (who would've guessed) the ultra cheap x99 board from china was actually very cheap in quality and caused a lot of system instabilities. Yesterday I...

I am running small ZFS pool (2x 2TB SATA SSDs) on my server. Not much things running, it was operating OK for long time (1.5 years). A week ago I upgraded the kernel while adding another node to my cluster - from the old one (not sure which version) to 6.1.15-1-pve. I did some reconfiguration of...

Hi all, i've got a problem migrating a vm in an 2 node cluster from pve02 to pve03. The vm is a pbs 4 with 2 disks (os 30gb & data 500gb). Both disks are located at a local zfs 2 TB nvme disk. the storage is called `nvme-2tb` on both nodes. the vm was configured in HA with a replication job...

Clickbait headline, but I think it is true :) Maybe others can chime in with their setups and why they need beefy hardware. Here is my PBS testimonial. Reading the documentation I was a little bit scared. Especially the storage part seemed brutal. Turns out it is not that bad and I...

I just installed Proxmox VE 9.1.1 to migrate from a wholly TrueNAS based solution. However, due to power outages, the ZFS pool that was managed by TrueNAS was in a degraded state. The disks themselves seem to be healthy, from their SMART properties, but I'm unable to import the pool as a ZFS...

I do want to say my setup is a little complex as it doubles as the boot drive and a special vdev in a 3-way Mirror. I have partitioned 200G just for the special vdev itself. I am running on a fresh install of Proxmox 9.1 with the pool running on the host itself. I have set special_small_blocks...

Hello, I recently updated my Proxmox PVE to 8.4 from 8.3. After the update I rebooted my Proxmox node, but after the reboot my VMs and LXC containers are not loading. It looks like my pool that has the location of my VMs and LXC, along with their backups are not mounting. During the boot, I am...

At least I'm assuming this is an issue with proxmox in combination with ZFS. (This doesn't happen on another proxmox host of mine with LVM, but that is PVE 8.3.2) I have an LXC on my ZFS (striped mirror) pool for VM/LXC data. It's currently running an IO intensive task, and this is the graph...

a bit of a Proxmox noob so sorry if I'm missing anything, having trouble determining the issue here and appreciate the help. I have a Raid 10 configured on my Proxmox server that's made up of 4 hard drive, 2 WD drives and 2 Seagate drives. A while back I was seeing some weird slowness issues...

Good day, We have used the Proxmox auto install feature using the `answer.toml` file since the release of this feature which is working really well for us. I was wondering if there was a parameter that we could use to disable thin provisioning for the automatic rpool creation? Looking in the...

Hello everyone, I am currently struggling a lot with my ZFS Pool (mainly SATA Issues). Every now and then i get a "SATA link down", "hard resetting link", "link is slow to respond, please be patient (ready=0)". This then leads to ZFS Pool error, which than degregate my whole pool. As I thought...

I'm using pve-9.0. An error occurred when I moved files between ZFS datasets. mv: error copying './zh-cn_windows_11_business_editions_version_24h2_updated_aug_2025_x64_dvd_08e70c15.iso' to '/rpool/test1/zh-cn_windows_11_business_editions_version_24h2_updated_aug_2025_x64_dvd_08e70c15.iso'...

Hello all, ## Brief Explanation i am trying to do a basic ZFS Pool setup to use for my VM Ubuntu after a great ammount of search on the internet i realised some uses specific folders set up inside the zfs pool in the proxmox terminal. so it would be better used on the ubuntu vm . Since i...

I feel like this is a very basic thing at its core but i am so lost on it that i require some assistance I finally created a VM ubuntu server inside my proxmox .after attempting a lxc container for weeks. At the moment docker is installed. I have gotten myself a 2tb NAS Drive (WD Red) i have...

Hi Until recently i used an early return 1 in the activate_storage function (within /usr/share/perl5/PVE/Storage/ZFSPoolPlugin.pm) to prevent ZFS pools from automatically re-importing after being exported manually with zpool export data-pool. This worked great until including PVE 9.0.9. However...
