zfs

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...

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...

I've got a single node setup w/a BTRFS mirrored boot drive that also houses my VMs (TrueNAS Scale, Win11 & Ubuntu) & LXCs (Plex, qBitorrent, Arrs suite). I've added a pair of Intel 4tb enterprise u.2 SSDs that I put into a ZFS mirror & want to move the VMs & LXCs. I can move the Win11 VM and it...

Hello everyone! I could use some help. I'm still new to ZFS and trying to troubleshoot an issue I'm experiencing. tl;dr I'm receiving i/o errors on my external backup devices when I try to use the Send|Receive commands. It is possible that 80% of the HDDs are bad, but I would like to rule...

Hi, Apologies I'm a newbie and if this has been answered on other threads but just want to make sure this will work before I buy these expensive SSDs.. I have a proxmox cluster who i have a boot drive/proxmox OS then i have a separate drive for zfs comprised of 2 pieces x 4tb SSDs in mirror...

Down another rabbit hole I go. This time, on ZFS on-disk encryption. I was surprised this is not enabled by default, but I'm a noob, so bare with me. You can run the follow to set encryption to on: zfs create \ -o encryption=on \ -o keyformat=passphrase \ -o keylocation=prompt \...

Hello, I would like to know when ZFS version 3.0+ is expected to be released and on which Proxmox version it will be available. Is it already possible to use ZFS 3.0+ via the Proxmox pve-test repository, or do we have to wait for an official stable release? I am particularly interested in the...
