zfs

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...

So I have this weird behavior after installing Proxmox 8.3.0 in two ThinkCentre M910Q's that are equipped with a 4TB SSD each. The machines came with a Windows pre installed which seemed to be working fine. I booted into the install ISO and installed Proxmox 8.3.0 (latest ISO download as per...

I tried to delete an unused container volume from a degraded zfs pool last night and rebooted the server afterwards. On boot the server is hanging with the following error "Panic: Error 61 from traverse_dataset_destroyed" I can get back into the server if I either disable the ZFS pool or...

I have a minsoforum ms-01 i9-13th gen and I plan to get another ms-01 but i9-12th gen as a secondary node. I use ZFS and I am trying to achieve extra head room along with zfs replicaton/HA. I know I need a third node to achieve quorum. So... I have another mini pc N5105 laying around but...

Hello, I've updated to Proxmox 8.0.3 some days ago and yesterday after rebooting the server using the reboot command, one of my zfs datasets is now empty (the other dataset on the same pool are fine). NAME USED AVAIL REFER MOUNTPOINT ssd-raid/storage 705G 732G 704G...

Hi everyone, i'm having issues with abnormally high RAM usage from boot. My server has 32GB of total memory and i'm autostarting 4 lxcs with about 2.5Gb of total ram use. ZFS arc is configured to 2GB as per: options zfs zfs_arc_max=2147483648 and is verified by issuing root@neuromancer:~#...

Hi, ich betreibe privat einen Proxmox Cluster mit 2 Nodes, jeweils AMD CPU (4vCPU), 32GB RAM, 1 NVMe SSD für OS, 2x HDD als ZFS Mirror für Daten / VMs. Die Nodes sind weitestgehend identisch mit Ausnahme der Festplatten: In der "guten" Node arbeiten 2x 4TB WD RED 3,5" HDDS, in der "schlechten"...

Hi, after some broken apt upgrades the installation is not bootable anymore (8.0). Is there any way to rescue a ZFS based VM stored on a local ssd? I fear a reinstallation cause this will erase the ssd fully a repair installation also didn't succeed (unable to find the existing installation)...

Hi there. Some time ago, I read that if someone wants better monitoring, then they need to set up specialized monitoring software and not rely on PVE graphs. Nevertheless, I do believe that ZFS users without monitoring software (like me) could benefit from showing ARC size in a memory usage...

I have an issue were the server keeps using all available space. How do i found out what is taking up the space? Also, were are backups stored, local backups. i backed i a number of vms locally but i do not know where those backups are. I want to copy those backup off the server.

Precursor My cluster consisting of 2 PVE hosts and a qdevice have been happily running for months, no issues. Last weekend I saw there were updates (it's my homelab, so pve-no-subscription updates), I ran them on both hosts, rebooted and everything seemed fine. Then I tried to use an USB...

Hello I have an issue with my Proxmox Backup Server. When I boot the PBS normally, the ZFS status shows "Suspended". However, if I boot the PBS in recovery mode and then proceed with "CTRL D," everything works fine, and the ZFS is online. What could be causing this? This is the current...

Hello I want to open this thread because all other threads, that I found, did not mention my use-case. Again, it is about the discard and ssd-emulation option because I don't get it. My current setup hast two internal zfs pools. Created with Disks -> ZFS -> create: ZFS One is SSD and the...

Hallo Zusammen, ich betreibe aktuell Proxmox 8.2.6 auf einem Mini-PC mit einem AMD Ryzen und 64GB RAM und einer 1TB NVMe. An diesem Mini-PC ist ein USB-Dock mit 4 HDD-Slots via USB3 angeschlossen. Ich konnte die Festplatten auch im Proxmox einrichten, jedoch hatte ich zum testen erst mal ein...
