  1. Sharing ZFS with VM and CT

    Hi, I've found a few things about sharing storage with VM and CT, but I haven't found the answer or I may not understand enough. I currently have 1x SSD with Proxmox, VM and CT on the server. Furthermore, 2x HDD on which I created ZFS. In Proxmox, ZFS is attached to point dataA. As VM and CT I...
  2. Add another drive to VMdata

    I am running a small server with only 2 drives. 1x60GB for the Proxmox installation, and 1x500GB for all the VM data. The 500 disk, is reporting 81% wearout, and I have begun to experience issues the last couple of days, which I suspect has to do with this wearout. Please correct me if that is...

  7. correct way to pause ZFS over iSCSI connections

    HI, I need to replace a switch in one of our datacenters, that is used by a couple of PVE nodes for almost anything (corosync, ZFS over iSCSI, node to node traffic for VMs etc.). The replacement shouldn't take long, but still it may take a minute or so. For all the traffic except ZFS over...
  8. [SOLVED] Replication in cluster - different ZFS storage on nodes - not available on node

    I have extended a test cluster with a new machine (called: pmx1885) which has its ZFS pool setup done after the install with the web-gui not with the installer (during installation time). This differs from my other cluster nodes in this case. The other cluster nodes (pmx2b,pmx1b,pmx2a,pmx1a)...

  12. dsl_scan_iss - multithreaded?

    Is there a way to configure ZFS so it would use more than one core for the apparently central process when scrubbing? I have two machines that started this sunday their usual scrubbing process. One is a 16-core Denverton (that's 16 Atom cores) and one is some 16-core Haswell system. Both are...
  13. Create a 100% sized disk for a VM

    Hi, I just installed proxmox and I had to destroy my mdraid (unsuported in proxmox) from previous ubuntu install. After wiping my 3 disks I went to ZFS section and created a ZFS pool with them : When I try adding a disk to my VM, I have selected it and we can see the raid5 with 3 3TB disks...

    ZFS Datastore - Fragmentation with SSD ?

    Hi, I have recently replaced all my HDD for 10 SSD for my ZFS Datastore. This is now extremely fast specially verify jobs (even if we can discuss the interest of verifying snapshots on a ZFS pool). The weird thing is that PBS reports fragmentation on the related pool : AFAIK, on a SSD...

    Dear proxmox community, I have proxmox (pve-manager/6.4-6/be2fa32c (running kernel: 5.13.0-19-generic)) installed on a ZFS root file system that is mirrored across two SSDs (sda and sdb).

  18. Mit PBS externe Speicher sichern

    Hallo zusammen. Da ich auf der Suche nach eine zentralierte Lösung für meine Backups bin, muss ich hier fragen, ob es mit PBS möglich wäre externe Speicher zu sichern? Was meine ich damit? Mit PBS kann man ja leicht die VMs und die Containers aus PVE sichern, aber eine VM bei mir läuft auf...

    I have 4 disks, each 2TB. I've set them in RAID5 using RAIDZ-1. I should have 6TB available. When I click on ZFS in the node itself is states that rpool size is 7.99TB. There are two storages: local (shows as 3.23TB) and local-zfs (5.67TB) Why those numbers? Why does that add up to 8.9TB...
