zfs

Hi all, We're running into a limitation in the GUI when trying to clone a vm from a snapshot on ZFS storage. On LVM this works fine, I know this works a bit different and also allows for non-linear snapshots which ZFS doesn't. A full clone however should be possible in my AFAIK. I'm able to...

I rebooted one of my HA boxes over the weekend, and a message popped up at the BIOS level that one of the 2 SSD drives is 'near life end'. The system has 2x240GB SSD drives in a ZFS RAID 1 (created during install by Proxmox). The mfg. is sending me a new drive (actually 2) as they appear to be...

It just occurred to me that the Reason why I'm getting such a MASSIVE overhead on my Backup Server (which has 2 x RAIDZ-2 x 6 Disks each) is because the Default ZVOL on Proxmox VE is (or probably "was" for a long Time, and many of my Virtual Disks are quite Old) 8k, which results in a Space...

I have a Proxmox (currently running version 8.3) server, that was installed on ZFS RAID1 a few years ago, booting Legacy BIOS mode. There is a 512MB EFI partition present on the boot drives, but when I switch the BIOS to EFI boot mode. nothing happens beside the EFI shell starting. Searching...

Hello, I have a very strange problem. I have two PVE 8.3.0 nodes with AMD Ryzen CPU's, 64 GB RAM, 1 TB NVMe with ZFS and 2x 2,5 GBit NIC's on each node. All VM's replicate from node1 to node2 every 15 minutes. Node1 is the primary node, node2 was just added. When I try to live migrate a VM...

What's shown in the dashboard for "Free" space (3.99TB): How much space is actually "Free" (1.70T): How can i get the dashboard to show this statistic accurately?

I see the last update to this topic was almost 3 years ago so I will stir it up again. I have a Proxmox cluster of desktop PC's running 8.3.2. Node 3 was previously running Ubuntu 22 with ZFS, 4 x 4TB raidz1 drives and 4 x 10TB raidz1 Vdevs (zdevs?) combined into a single volume of about...

Hi community. I've just installed latest proxmox ve on a small server with 4 SSDs connected to the backplane. I chose ZFS RAID10 in the installation to have everything on these 4 SSDs. I updated, restarted etc and when I just wanted to deal with vms I realised that local-lvm has status unknown...

Hi, I know barely enough to make my life difficult and yes, searched, read, tried many steps found here and elsewhere. Essentially, mounting a mirrored zfs dataset in a container to run Samba file sharing. Saw this guide: https://blog.kye.dev/proxmox-zfs-mounts and followed it. Next steps...

Hello! can i delete a snap like: STORAGE/VM/KVM/vm-122-disk-0 STORAGE/VM/KVM/vm-122-state-prenelarge simply: zfs destroy STORAGE/VM/KVM/vm-122-state-prenelarge ? Thanks

Good day, I have renamed a ZFS dataset that contained a lot of snapshots. I just used zfs rename tank/data/mydataset tank/data/newdataset to rename the dataset and it looks like it worked. Also when I list the snapshots using zfs list -t snap, they are still all present, even with the correct...

I have a proxmox cluster v 8.3.1, each node has a boot drive (rpool) and 2 SSDs mirrored with ZFS (vm-storage0). Under cluster>storage there are listed local, Type directory local-zfs, Type ZFS vm-storage0, Type ZFS root@prox3:~# zfs list NAME USED AVAIL REFER...

I want to re-install proxmox from scratch, but use another two disks in a zfs mirror on the same machine. While installing, it tells me that there is already a zpool "rpool" and therefore I cannot install proxmox. Anyway, I chose to rename the pool to something like...

Hello everyone, first of all, I'm new to the Proxmox world and, in a way, I have very basic knowledge of Linux virtualization. I’d like to seek advice from more experienced users if possible. I have 2x HP DL380 Gen9 servers with the following specifications in terms of memory and storage...

Hi, I am wondering whether this is a correct usage of my hardware which runs PVE. I have a Dell PowerEdge R630, 2x HDDs, and 2 SSDs. From what I understand, ZFS is not recommended to run on hardware RAID. The controller (PERC H730 Mini) is currently set to HBA mode and I configured the Proxmox...

Hi, I have recently been moving some large LXC containers between two ZFS pools on the same machine and I've noticed something a little odd... Whereas moving a VM basically screams along as fast as the disks can manage, moving the containers is much slower - in my case, I'm getting ~70MB/s when...

Good afternoon, I’m planning to back up some documents in a Windows Server VM using the Windows Server Backup service. I have an external hard drive that I would like to use for this purpose. What would be the best way to add this disk in Proxmox and then make it available to the VM? Model...

I have a freshly formatted set of 4 1TB disks in RaidZ2. the GUI under node->Disks->ZFS shows 4.09TB, while the node->local-zfs->Summary shows 1.92TB. Here's output of zpool list #zpool list NAME SIZE ALLOC FREE CKPOINT EXPANDSZ FRAG CAP DEDUP HEALTH ALTROOT...

Hi all, I recently stumbled when trying to migrate a VM from a node with an encrypted ZFS dataset to a node without encryption: ``` cannot send nvmepool/vm-310-disk-0@__migration__: encrypted dataset nvmepool/vm-310-disk-0 may not be sent with properties without the raw flag ``` It's not a...

I've been chasing a ghost since upgrading to proxmox 8.3 (correlation is not causation, so I can't point to 8.3 just yet). Random LXC containers start to exhibit i/o errors. This is only "noticed" when a nightly backup runs as it then errors, but fails on those specific LXC's. The storage is...
