zfs

I have a Dell R530, I recently switched from using RAID5 disks with the built in raid card to HBA mode and using ZFS. Before when I was using LVM, my sabnzbd could max out my connection (between 120-150mbps), however after switching I'm only hitting between 5-30mbps consistently. sab reports...

Hello, I have 3 basically identical systems I’m having put together in a cluster. 2 out of the 3 have the same amount of storage but 1 of them has only half the amount. I want to make everything zfs and I am using intel or micron enterprise ssds. With zfs would I be able to slowly upgrade the...

I have to get on an airplane in order to visit my servers. Or use remote hands. You know how that can go. So, I'd rather not _need_ somebody visiting my servers. Or at least as little as possible. And some of its old junk. So it dies. Enter the spare disk conundrum. It's easy to find ZFS...

Hi guys, since I'm still at the beginning with proxmox (coming from unrai*) I'm wondering about the right disk layout. I have quite a wild growth concerning my hard disk landscape and wanted to ask if a ZFS makes sense or rather LVM? How could a possible ZFS make sense with the disks? I also...

I have a proxmox ve with a single ZFS, named zpool. Inside that proxmox ve node, I have a privileged lxc container with PBS installed via proxmox scripts. When I go into the PBS into storage, I don't see the ZFS storage and I get this error: Bad Request (400) command "zpool" "list" "-H" "-p"...

Hallo zusammen, ich lese zwar schon geraume Zeit mit und habe zahlreiche Hilfestellungen gefunden. Jetzt aber habe ich mich registriert, da ich nicht weiter komme... Ich möchte von meiner Synology Rackstation umsteigen auf Proxmox und die Sync nur noch zur Datensicherung nutzen. Dazu habe ich...

I am observing some very high (>40%, sometimes 80%) IO Delay on Proxmox VE 8.2.2 with pve-no-subscription Repository. Looking at some Posts over this Forum, this may be due to not using Enterprise-Grade SSD, although to be honest I don't necessarily "buy" this justification. I am using Crucial...

Currently PVE runs on 256GB NVME M.2 drive installed on PCI adapter. I've purchased Intel HPE IBM P3600 1.6TB HHHL PCI-E NVMe and I would like to install it and replace system drive. My plan is to remove current drive and connect it via USB3 (adapter) and put in empty PCI slot a new drive...

Alright, super noob here to bear with me. But this is my backup sever that's also serving as my practice server before migrating everything to it from my truenas server. I just need to have my entire TANK visible on SMB of which i'm following this youtube tutorial and i'm good up to the 12:37...

The documentation is clear on the command needed to replace the failed drive after the new one is installed: zpool replace -f <pool> <old-device> <new-device> However, I am unsure of what exact device name to use. The output of zpool list -v and zpool status both show device names that are...

Hi@all, I recognize a wire behavior / issue with my pve installation. My servers running most likely the same both have an Gigabyte MC12-LE0 with 32GB RAM. One server has an AMD R5 3600 and the other one an AMD R7 3700x. I installed pve on a NVME SSD on the server with the R5 3600. On the...

I have 64 GB ram in my server. As ZFS is configured to utilize maximum RAM, I tried to reduce with following config in /etc/modprobe.d/zfs.conf to around 8 GB options zfs zfs_arc_min=8388608 options zfs zfs_arc_max=8388608 but still zfs was using 28 GB.

running a very simple set-up with Proxmox on ZFS I'm looking to have snapshot of everything in /etc and other select directories. Essentially / without rpool and subsequent volumes. Since df -h shows mountpoint to be /root/RPOOL/pve-1 / i tried: zfs snapshot -r rpool/ROOT/pve-1@may2024...

hello, I'm running an opnsense firewall guest and filesystem is ZFS, this the only "production" instance right now i have disabled some ZFS features on the guest already just wanted a confirmation that this is harmless: checksum compression encryption sync xattr=sa also should i disable the...

I am currently planning to migrate to Proxmox, but would like to find out some important things before I actually take the step. Before I ask my questions, I think it is best to describe my setup/requirements: I don't run many VMs, but a few with high IOPS and consistency requirements, as I run...

I want to share the results of me trying to mount multiple zvols in an lxc container to share them using smb/nfs/sftp The command outputs are trimmed to only include the relevant parts. Goal: Gounting ZFS-Pool into lxc Container. Prerequisites Proxmox VE 8.2.2 Container 102 (to mount to) A...

Hello, I want to shrink the size of a vm from 100G to 30G. I booted the vm into gparted and resized the partition to 29G I shutdown the vm ran "zfs set volsize=30G rpool/data/vm-201-disk-0" to leave a little overhead ran "qm rescan" and got the message that the disk-0 has no 30G instead of...

Hi, as mentioned in the title, I am running in issue when there is something wrong with my vm-storage zfs pool I just decided to move the pool from an NFS share on truenas (virtualized) to native proxmox zfs, but yesterday when I was trying to move the VM disks from the original source to the...

I have Proxmox 8.2 running CT's and VM's on Linstor - DRBD shared storage with underlying ZFS. I can create snaptshots without any problems. In fact PBS uses it to backup running containers. As far as i know snapshots is a prerequisite for converting CT's to a template ? I created a Debian 12...

I'll preface this with saying that I'm fairly new to Proxmox. I have built a couple of nodes multiple times as I've torn them back down and started over as I've learned more in my journey. Right now I've got two nodes and will be adding a third one shortly. The two existing nodes are identical...
