Wir haben eine VM mit Samba, die mehrere btrfs Volumen hat.
Eines der Volumen ist auf drei Virtuelle-Platten verteilt.

Beim File-Restore wird das Verbunde Volumen nicht eingelesen, die Platten sind jedoch sichtbar, alle anderen Daten können wiederhergestellt werden.

Backup is missing some files

Hello,

I have setup a backup für my two virtual machines, which runs once per week at night. Tonight it startet writing some backup files to my NAS, but to my surprise one of the backups seems way to small.

I downloaded a big Linux ISO with 5GB on one of the virtual machines, the file was written to a SSD drive. The backup file created is below 1.5GB so the ISO seems to be skipped. The log of the backup shows no error.

Here are my current backup settings:

Fibre Channel SAN with Live Snapshot

Hello,

we like to integrate our Fibre Channel San to Proxmox.

We already did this successfully with LVM, but there we cannot make Live Snapshots.

But is there maybe a way to make it happen with a GlusterFS Volume to Connect 4 Nodes with a shared Filesystem to the Fibre Channel SAN?

The San also Supports ISCSI, but this does not bring anything because it has no ZFS Support.

Hello everyone,

I'm new to the wonderful proxmox ecosystem.

I recently configured a proxmox cluster with ceph, but I don't understand the remaining disk space values displayed.

Here is a description of my configuration :

  • Dell PowerEdge server (VE 8.3.3 installed on NVme with RAID1 BOSS Card 2x480GB)
  • "VM+Management Access Network" : 10Gbps > on switch

Performance comparison between ZFS and LVM

Hi,

we are evaluating ZFS for our Proxmox VE future installations over the currently used LVM.
ZFS looks very promising with a lot of features, but we have doubts about the performance; our servers contains vm with various databases and we need to have good performances to provide a fluid frontend experience.

From our understanding ZFS needs to have direct access to the disks, so the server is required to have a transparent capable controller or none at all.
Instead of use the controller...

Quick HOWTO on setting up iSCSI Multipath

Hi Everyone,

I originally included this HOWTO guide as a reply to someone else's post but am posting in its own thread as it may help others who struggle to get proper iSCSI MPIO working on a Promox cluster. Coming from an enterprise VMware ESXi background, I wanted my shared storage setup the same way in Promox (albeit without LVM snapshots but Veeam fills this gap). It should be noted that this configuration is entirely done from shell and not through the web UI. I found that the GUI...

I'm currently using a 4 node proxmox cluster with a CEPH filesystem as storage. Of these 4 nodes only 3 of these are running and 1 is offline.

Which is intended for my purposes.

I have a VM (104) which is currently stored on an erasure pool. The erasure pool is only stored on the online nodes. The proxmox4 node is not participating in this CEPH pool.

However when I try to remove the disk for VM 104 (or in this case, the whole VM), proxmox shows an error that it can't acquire...

the problem is that whilst nordvpn connects and works as expected, it only works for around 15-30 minutes then at that point i get zero DNS resolution from within the LXC. the vpn is still connected, and i can still ping any WAN IP address, but any attempt to resolve DNS fails. i disconnect the VPN, reconnect and it's rinse and repeat.

In Proxmox 8.3 I created two VMs with Windows Server 2019 enabling "QEMU guest agent" in Options. In the VMs I installed QEMU guest agent (108.0.2) and set the related services to start automatically at boot.

Every morning in these two VMs I find the "QEMU Guest Agent VSS Provider" service stopped. If I restart it, the service starts without problems.

I think the problem is related to the Proxmox Snapshot Backup that I automatically perform...

Hey friends,

Observing strange performance limitation.

EDIT: ALL SSD & NVME are Enterprise Level! No consumer stuff built in

Backups PBS & Veeam topping out at around 200 MiB/s..

Esp. Veeam is telling, the bottleneck is actually the "source", which is the ceph cluster.

Backup Vault is capable of much more than this (24 x 14 TBs ZFS Z2 volume)

Each node is utilizing MLAG with 2x 25Gbit/s.
VMs using 10Gbit/s NIC virtio.

None of the OSD is showing high latencies or commit/apply...

Scenario​


I have a Proxmox VE 8 cluster with 6 nodes, using CEPH as distributed storage. The cluster consists of 48 OSDs, distributed across 4 servers with SSDs and 2 with HDDs.


Monday night, three OSDs reached 100% capacity and crashed:
  • osd.16 (pve118)
  • osd.23 (pve118)
  • osd.24 (pve119)
Logs indicate "ENOSPC" (No Space Left on Device), and these OSDs are unable to start.
