zfs

Hi everyone, I'm currently facing a strange replication issue within my promox cluster. On one node, I get an error from every VM indicating that its replication job gets timed out, but this occurs only once a day. command 'zfs snapshot rpool/data/vm-108-disk-0@__replicate_108-0_1750802882__'...

I have the following zfs and I have uploaded a ISO file to IData/ISOs If I than try to generate a new VM and I want select the ISO under Storage it is already ZFS-ISO but under ISO image I have no possibility to choose the image. So what did I wrong?

Hi! I am currently testing disk performance with different setups, just to find out what is working best, and I am observing strange behavior - or I am simply doing something wrong here :-) My Setup: - Proliant ML30 G10 / 64GB Ram (not a rocket but shold do) - Brodcom HBA 9400-16i with an...

Hi everyone, I've ran following server for a long time: 1 SSD with Fedora Server installed 2x large HDD's in ZFS mirror in Fedora Server I've upgraded my server hardware and now want to use proxmox. I've installed it and added some drives for the disk images to store the Fedora Server VM. I am...

I'm not strong with Linux, but I think I have figured out that my ZFS pool ran out of space. I noticed the issue when the TrueNAS VM the volume is attached just hangs at boot at the ix-zfs.service - import ZFS pools and the Proxox status = io-error. I need help mounting it and freeing up...

Hello everyone, I have a ZFS1 pool made up of 10 disks. When I first created the pool, I only had 5 drives, and they formed the first vdev. At the time, I used /dev/sdx to set them up. Later on, I added another 5 drives to the pool and this time I used the /dev/disk/by-id path. So the pool...

Good morning! My media server had been acting funky so I decided to rsync the most recent data to my backup server in case something was wrong with a drive. When I started working with a particular drive I noticed it was rsyncing very very slowly. I pulled up the Proxmox web interface and...

Hello, I had a drive disappear from my ZFS pool (1 failed drive), so I decided to replace it. After the replacement, I rebooted the system and the pool came online successfully. However, when I ran zpool status to list all pools and disks, I noticed that two of the disks were not recognized by...

Hallo Zusammen, auf meinem PVE 8.4.1 betreibe ich eine HDD als ZFS. Zum Einsatz kommt eine Ironwolf Pro 4TB. Laut der Übersicht im PVE sind auf der Platte 2TB belegt. Wenn ich dann unter "VM_Disks" nachsehe was denn da alles installiert ist, komme ich nur auf ~ 1,2 TB. Das deckt sich...

I'm drawing up plans for remote backups of a few ProxMox servers, non-cluster single machines in different locations. After reading through the forum, AI tools and other sources, it seems like using ZFS send/receive to a remote server also running ZFS ( rsync.net or my own server) would be the...

This thread to document what happened and how this was fixed, just in case this can help someone. Running pve-manager/8.4.1/2a5fa54a8503f96d (running kernel: 6.11.11-2-pve) in a single host set-up for a lab environment. The system typically is stable, until it is not. After a few 'hangs' this...

Hi everyone, I run a small home lab for myself. My applications consist of a firewall and game servers or web apps. I've just had a drive start to fail (see SMART values) and I also have gotten IO errors in my VMs (I presume they have files in the bad blocks). How do I go about fixing this. I...

Hi all, Today I added dedicated corosync interfaces and network thinking that would fix my 'nodes fencing for no reason' problem... However, it seems like nodes are still fencing for no obvious reason, even more than ever. (Like every 15 minutes). Can anyone help me troubleshoot this issue is...

I just ran into an issue trying to live migrate a VM; source and target are zfs, version is 8.4.1 Error message: online migrate failure - block job (mirror) error: drive-scsi0: Source and target image have different sizes The disk was created by importing from a Hyper-V vhd image, that turns...

Something pretty strange happend again to my ZFS pool today, but it is probably best to start from the beginning. For multiple years I had a WD Red and a Kingston DC NMVE as mirrors. Few months ago I got a email that the Kingston drive was gone. I did not think much of it, ordered a 990 Pro...

Hello, I am currently having a problem with mail notifications, I have 3 servers: pve-server-01, pve-server-02 and pve-server-03(This last one is only used as a quorum device). A few months ago I configured the notifications using an SMTP server(Gmail) in Datacenter->Notifications and until...

Sometimes it can happen, a ZFS pool become 100% full. Since ZFS is a COW (Copy-on-Write FS), it is very difficult to remove data from it because at least enough space must be free to write a timestamp. To prevent this from happening, you can create a dataset and reserve some storage space (~20...

First I will try to explain our use case: - Remote industrial hardware - Only two drive ports, 1x Sata + 1x M2 - HMI + DAQ functionality (Human Machine Interface and Data Acquisition) - Deployed on hard to access areas, with no IT personal deployed in locally - Uptime is important Now I...
