    Hello, everyone. New user here. First, I'd like to acknowledge and thank everyone who has developed and contributed to Proxmox. It appears to be a highly polished product and I'm eager to get started. I went through the default install and saw that a few partitions were created. The data...
  3. ZFS mit Hardware Raid für Storage Replication

    Hallo zusammen Ich spiele momentan gerade etwas mit Proxmox herum um es zu lernen, und bin auf folgendes Problem gestossen: Mein Server (HP Proliant dl380 gen9) hat einen integrierten Hardware Raid Controller (Smart Array P440ar). Momentan habe ich ein Raid10 Array (ext4) aus 4 ssds, welches...
  4. Samsung SSDs a right ashift size for ZFS pool?

    Hello, I'm creating new zfs pool (raid 1) And I have 2x Samsung 860 evo 512GB I know that proxmox like to write a lot of stuff to disks (my setup 45 gb per 24 hours average, all VM idling none of them writing to disks) And I didn't find any satisfying result about ashift for ssd. Is it right...
  5. Need help with configuring drives for redundancy

    I have an old AMD Phenom x6 PC and figured I'd tinker around with it. My disks are as follows 3x1 TB (currently in zraid) 1x2TB 1x8TB ( newly acquired and shucked from a WD black) I don't need more than 5-6TB of storage atm. I'm thinking there is a way to mirror the 3 1TBs and the 2TB on the...
  6. Wrong approach to ZFS dataset for VM image storage?

    I have an nvme pool that I want to use for a) storing VMs b) storing mails (by a mail server run in one of the VMs) For this purpose, I have created, via command line, a ZFS pool with two datasets, "VMs" and "mail". (mail is obviously shared via nfs with a VM). I have then, in Proxmox GUI...
  7. Cluster: Host node ZFS redundancy with additional (storage) replication for VMs /CTs - best practice?

    I am looking at the option of configuring a PVE cluster with storage replication (using a ZFS pool across the cluster nodes) so VMs and CTs can be moved to another node if the original host node has a failure. This is probably a PVE independent question but: when I create the initial ZFS...
  8. [SOLVED] df shows wrong Size/Used/Avail for zfs pool

    Hi! I am using ZFS as boot and storage system. All packages are on the newest version. df -h shows wrong Size/Used/Avail. Actually the Size and Avail are the same. zpool list -v NAME SIZE ALLOC FREE CKPOINT EXPANDSZ FRAG CAP DEDUP HEALTH ALTROOT rpool 476G...
  9. Hard Drive Pass-through not seeing partitions

    I am running an Ubuntu 18.04 VM which the install disk is on my PVE server local storage. I am trying to do pass-through of the hard drives on the PVE server (not the install SSD) to give the VM direct access to the storage and zfs management of the disks. The disks actually came from a...
  10. [SOLVED] ZFS replication for VMs with multiple disks

    Hello I was just testing Proxmox 6.2 and I was wondering why only the second disk of the vm was transferred fully, and first one was just incremental (and the zvol was there). Well, actually it seems that I've just set a replication (from GUI) and forgot about it :p. But the question remains...

  12. Geo split cluster?

    I have several servers rent in two datacenters. This is done to overcome DC outages (which is rare case but still happens), and so we'd like to have data from one DC to be copied to second one so we can use it to run reserved VMs with that data. The data itself is Postgresql databases and...
  13. ZFS Pool is degrading alternately between two disks

    Hi there, I got a degraded status for the second disk of a pool, checked smart status and cleared it. A day later I got the status for the first disk: ZFS has finished a scrub: eid: 63 class: scrub_finish host: pve time: 2020-05-18 18:10:07+0200 pool: DiskPool state: DEGRADED status: One or...
  14. [SOLVED] local-zfs came on node join

    Why is local-zfs on the other node? Local-zfs came to the other node on joining the cluster. When its wrong here, how can I get rid of it? Thanks ~Marlon
  15. ZFS and special device how to use unused free space ?

    I know this might be a stupid question, but it also my be a good question. I've done a mistake and setup a special device with 700+ GB in mirrored mode, the mistake being too much space dedicated for this. I have already a separate partition from this for SLOG, but that's unrelated to the...

    I have setup my install to have the following: 2x 250 gb SSD in zfs raid1 for proxmox os.- nothing else here 1x 1T SSD - I intend to use this to hold the VMS Synology nas for backups ( NFS). I am worried about the use of the single 1T ssd for the vms. I am planning to use zfs raid0 on it...
  17. ZFS mirrored rpool disk ID changed, cannot zpool replace

    For my rpool, I have two mirrored NVME SSDs added by-id. However, it seems that one of the ids has changed for some reason, and I am now showing degradation of my rpool: root@Skywalker:/dev/disk/by-id# zpool status -x pool: rpool state: DEGRADED status: One or more devices could not be used...
  18. replace zfs (boot) disk in uefi environment pve 6.1

    I am pretty new to proxmox but very impressed by it's possibilities. Having setup a PVE 6.1 environment (3 x 2TB sata, AMD Ryzen 7 2700X Eight-Core CPU, 64GB memory) which is running some limited production as test without any problems. One of the 3 disks (sda) is giving errors so i want to...
  19. PANIC: * invalid TYPE 140 (My confidence in ZFS on Linux for business use is is strongly strained)

    Hi all, what happened? A PVE server commissioned in 2018 ceased service after almost 2 years of trouble-free continuous operation; server access was no longer possible, neither PVE-GUI nor other services; ping was still possible. A login to the physical console was still successful. The...
  20. ZFS: howto add 'new' HDD & transfer data from old one

    Hi guys Fairly new to Proxmox/basic linux knowledge, and a little time ago I've managed to create a zpool (raidz1 raidz0) with a HDD (testdisk, 1TB) to be fully used as storage for a container and to be shared on the network. System, LXC's and VM's are on a SSD (rpool) To get this working it...
