zfs

Hi everyone, I've set up a three-node Proxmox cluster using ZFS, but I just realized—after searching the forums—that I made a mistake in my storage configuration. I assigned different ZFS pool names on each node, so when I try to configure replication, Proxmox fails because it expects the same...

Hi everyone, This is just in case someone stumbles upon the same error while troubleshooting. I am not asking for help, though I’m open to explanations if anyone has one. Roughly two years ago, I created a new Proxmox host with VMs. Two weeks ago, I read about CPU types—something I had never...

Salam. Sorry no idea if I'm posting in right thread. I'm using proxmox for some months now. Got various VM and LXC running. Got a primary hdd LVM and another hdd turned to ZFS. I have my NEXTCLOUD with ZFS mounting. 1. Whatever I'm uploading, is it being stored to lvm or zfs? (Added...

Ich habe auf einer ssd karte proxmox installiert, eine externe hdd als zfs eingebunden und nein vm windows auf die externe festplatte installiert… Leider hatte icj mein proxmox zerschossen irgendwie funktioniert da nichts mehr. Jetzt habe ich mir proxmox auf einem anderen rechner neu...

Hello, I'm currently trying to find the reason for a size discrepancy between the Hard Disk of a VM and the ZFS used size on storage. A Windows VM was created with a 500 GB Hard Disk on a ZFS Storage. Then this disk was expanded within Windows Disk Management to 1500 GB. "zfs list" shows...

I am running a server with 24 - 2TB drives on an Areca 1280 Raid controller with all disks in JBOD mode. I have tried both RAIDZ2 and RAIDZ3 and added all 24 drives, assuming the hot spares are built into the array by Proxmox. Yet every attempt fails. I can build smaller arrays. It spits out...

Hi, I tried to answer a question with a link explaining Proxmox disk usage displays in the Web GUI, but I did not find a posting explaining it (possibly because I searched wrongly), so I decided to write a brief overview. I try to explain simple, even if sometimes not 100% accurate...

Hello everyone. I recently acquired 2 HPE DL380 GEN11 servers. Each node has 512GB of RAM and 4 PCIe5 NVME drives of 3.2TB (HPE, but manufactured by KIOXIA). Given my use case, where the goal was not to have shared storage but rather a cluster with VM replication, I created a logical volume for...

I've migrated all my VMs across to Proxmox over the last 12 months, all that remains is an encrypted one. I would like to rebuild it from scratch as a VM on proxmox. I understand ZFS encryption is the way to go. I'm trying to add ZFS pool using the GUI, but my disks do not appear in the list of...

Hello there, first of all: I'm not new to Proxmox, but I'm a complete newbie at ZFS. Why I came across ZFS? I have a bunch of 2TB and 4TB Hard-Drives lying around and also 2 1TB M.2 SSD´s. At the moment I use a Hardware-Raid Controller to get a "Drive" (or better 2 Drives) into my Proxmox...

Hi everyone, I'm looking for advice on how to get the most performance out of my hardware. I have a Lenovo ST250 with a RAID 530-8i controller (flashing to IT mode is not an option). My disk setup is as follows: 1. 1x Intel 4520 M.2 SATA SSD (480GB) 2. 4x SAS 10K 12Gbps (900GB) 3. 2x SAS...

I have a fast 2TB NVME SSD and a slow 4TB SATA SSD inside a RAID0 zfs zpool. I like zfs (over lvm which I had before) for its versatility in managing storage (e.g. one pool to use, including the pve root), however I'm running into the issue that my mixed hardware slows down. With LVM, I could...

Hi Our PBS today ran out of storage, it's sitting at 100% and "zpool status" outputs "no pools available" We've been getting (os error 28) Full error log: "ERROR: Backup of VM XYZ failed - VM XYZ qmp command 'backup' failed - backup connect failed: command error: No space left on device (os...

Hello, Last night I had to shutdown my server during a power outage. Prior to shutting down, everything was working as normal. I was able to do a safe shutdown before the UPS ran out of juice. This morning I turned everything back on, and since then I have been receiving a "Failed to initialize...

Hi. I have a situation. A virtual machine has 1450GB disk. When i active the replication, the size grow very much: NAME USED AVAIL REFER MOUNTPOINT SAS0/vm-701-disk-0 2.44T 2.13T 1.01T - # zfs list -t snapshot NAME...

New install PVE 8.3.3, host has 256gb RAM, i have an 11TB ZFS pool (in HA with another host, identical config) I have 118gb of RAM used in VMs right now and the host shows 239gb RAM used. I read that since PVE 8.1 ARC is reduced to 10% of the host's ram so why am I getting this high usage? I...

Hi there, I have two Proxmox VE 8 servers called proxmox1 and proxmox3. The backups of proxmox1 are validated every night (copy to Debian desktop, decompress, start and ping). Proxmox3 is an old Dell Precision T1650 meant to serve as backup in case proxmox1 fails. It has a 512MB NvMe on a...
