zfs

Hi I attached 2 disks to my proxmox node and made a zfs mirror and place 1 lxc on there currently I want to use sanoid to take snapshots - hourly / daily and weekly - which I want to then syncoid to another zfs pool. I am concerned that all of the snaopshot and bookmarks will affect proxmox

I have a Proxmox Server with ZFS (mirror - two disks). After a power outage, i get an error that the pool it was already there. I check /etc/zfs/zpool.cache and it was empty so i run this zpool set cachefile=/etc/zfs/zpool.cache pool After reboot, i get this error message cannot import pool...

Hello everyone, This is my first post on this forum and I am a bit of a noob so I appreciate your patience. So I just upgraded my proxmox server to 9 and I can't boot into the system. It is stuck at busybox (initramfs) and here are some of my outputs: zpool status show all of my pools (rpool...

Proxmox 9.0 Last night my backup job failed with the log: INFO: filesystem type on dumpdir is 'zfs' -using /var/tmp/vzdumptmp417990_104 for temporary files INFO: Starting Backup of VM 104 (lxc) INFO: Backup started at 2025-08-14 21:04:48 INFO: status = running INFO: CT Name: jellyfin INFO...

I upgraded to 9 - and managed to break my zpool imports. There seems to be some kind of error in the cache, but despite removing and recreating the cache, nothing fixes the error and allows the system to boot. I've been able to boot via chroot on the proxmox installer. Anybody have any suggestions?

Upgraded to PVE9 last night. My setup is Pve running on a 500 gb Nvme (ext4) which has about 5 VMs and 3 LXCs. Two (2) of the VMs include Immich and Plex which store data on the ZFS pools. Following the upgrade this is what i've noticed; is there anyone who could provide assistance on this...

Hi I was able to upgrade to PVE9 without issues; I am running 5 VMs (including OPNSense) and 3 LXCs and lost internet connectivity a few hours later. Was unable to see any output or access PVE via the web interface. Had to restart the machine and everything is working fine now. Issue - 1: I...

This thread should provide some information on how you might be able to optimize I/O performance for your VMs. Please: If you post answers with test-outputs - use the 'inline spoiler' ;) For those that are interested in the charts and values see: docs.google.com/spreadsheets Warning: We are no...

Hallo, ich nutze den PBS auf Bare Metal und habe neben dem PBS auf das gleiche System ein SMB-Server für Windows Clients Backups eingerichtet um ein zusätzliches NAS zu sparen (Siehe vergleichbarer Thread hier im Forum: Link). Beides ist datentechnisch von einander getrennt: der PBS und der...

Hi folks, I'm trying to manually migrate (live migration) of a VM from a single node proxmox to a proxmox cluster. I have tried many different things, like checking the fingerprint, permission on the token, tried with vm online and offline, and many other but I can't get rid of the error device...

Hello, I've activated the LIO iSCSI target on some promxox hosts for sharing local NVMe's over iSCSI (beside using those NVMe's for replicated storage) But now my LIO target LUNs are not restored on boot anymore: systemd[1]: Starting rtslib-fb-targetctl.service - Restore LIO kernel target...

I have a case or two with "slow" storage imports causing VM start failures. In my case big"ish" ZFS pools takes quite a time to "settle" before the VM can start, so a reboot has the VM fail to start and needs manual starting. Anybody else having similar issues? The current solution I have, is...

Hi helpful forum folks, I recently installed Proxmox VE 8.3.3 on the eMMC of the FriendlyElec CM3588 (with Rockchip 3588) using their instructions and the official image on the FriendlyElec website . I installed two 2tb NVME drives to the board. When I go to add ZFS pool, I get the following...

Hello guys! Can i migrate on proxmox installation in LVM to ZFS without formatting the system? Thanks!

Hello, I am looking for assistance with accessing my VMs now that I ran: zpool destroy - f <MYZFS> I thought all my VMs were on a separate SSD... So, I had a pfsense VM and I now can't access my workstation through that network after running zpool destroy. I hooked up to the PVE machine and...

Hello, I recently rebuilt my PVE machine (R720XD) so that the HBA is in IT mode and i now can use ZFS. When installing PVE i chose raid Z1 and selected all the drives. I have read several forums and am aware that using Z1 like this isn't recommended but it works for what I need. Performance...

Hi everyone, We currently have the following setup running under VMware, and I’m looking into migrating it to Proxmox VE: One physical server: HPE ProLiant Gen11 One external storage system: HPE MSA 2060 FC, configured with a RAID MSA-DP+ array built from 24 HDDs The server is connected to the...

Help me understand the new ARC limit default of 10% instead of 50%. The only OOM scenarios, where unshrinkable TXG is a problem, I can come up with are: A: System with 32GB RAM and 10GBit NIC. 10% instead of 50% limits TXG to 3.2GB instead of roughly 5.8GB (limit is not ARC settings but...

Hi everyone, I'm currently facing a strange replication issue within my promox cluster. On one node, I get an error from every VM indicating that its replication job gets timed out, but this occurs only once a day. command 'zfs snapshot rpool/data/vm-108-disk-0@__replicate_108-0_1750802882__'...
