recovery

Is there a simple way to get a system back to a previous version of proxmox, if the upgrade fails? Just wonder, because I currently have some issues with upgrading from 8.2.2 to 8.3... I'm only thinking about the proxmox ve host, not the VM's. I could run a script that backups the important...

I just tried to integrate a new (so I am a noob wrt ProxMox) ProxMox server into my existing private PKI. So I wanted by web sessions to use a cert I provided. To create the certificate: - I created a new 3072 bit key and exported it in PEM - I created a certificate signed by an intermediate...

Moin, leider scheint meine Serverhware ihren Geist aufgegeben zu haben, fing an mit random freezes und reboots und kommt nun gar nicht mehr hoch. Peripherie von RAM bis Netzteil gecheckt, nix zu wollen. Jetzt zu meiner Frage... root lief auf einer SATA und als storage ein ZFS mirror aus 2x M2...

I am testing ProxMox as a Vmware replacement. I have been testing recovery approaches like backing up /etc/pve and doing a disk image, and then testing scenarios like doing an upgrade, then attempting to rollback or purposely destroying a Proxmox boot disk. I am using a single disk for the...

I screwed up big time and lost my ZFS pool ! How can I retrieve it, I need help ? I’ve been using PVE v8 for few months at home, mainly for windows & macOS VMs and testing new systems, inc Plex & TrueNAS Core It was going great and recently added Proxmox Backup Server in order to backup the...

There are cases when you make changes in your configurations, only to want to partially revert it back. NOTE See how you should have already been backing it up [1]. Alternatively, you get hold of stale (from non quorate-node) or partially corrupt config.db - see also how to recover it [1] -...

Ein Proxmox Host unseres Cluster schafft es nicht mehr hochzufahren und bleibt immer bei: Found volume group "pve" using metadata type lvm2 5 logical volume(s) in volume group "pve" now active /dev/mapper/pve-root: clean, 69080/6291456 files, 5799043/25165824 blocks stehen. Wenn ich den...

The Headline: I have managed to kick all 3 of my nodes from the cluster and wipe all configuration for both PVE and CEPH. This is bad. I have configuration backups, I just don't know how to use them. The longer story: Prior to this mishap, I had Proxmox installed on mirrored ZFS HDDs. I...

Hallo zusammen, Ich nutze seit einiger Zeit Proxmox als Ersatz für VMWare (machte damals schon Sinn und nach den letzten Berichten noch mehr :-) ). Nun möchte ich, da mein Server sowieso läuft und die betreffenden Rechner schon älter sind, die Rechner virtualisieren. Der eine oder andere...

I went through the process to upgrade from 7.4 to 8, in trying to get the pve7to8 tool onto my machine I appear to have corrupted the install so badly that when trying to boot it goes through bios and then has a black screen. No errors or anything. I can see from a recovery image that the Hard...

Hello, I'm managing a cluster of 4 nodes using proxmox 7.4-17 with CEPH. After a messy shutdown caused by a long power outage, a couple of VM images were corrupted, but we could restore them from backup. However, two of the OSD services refuse to come back, showing this kind of error: Apr 18...

my name is idiot. I ran tteck's post install script on my ve after having good success with a similar one on the backup server. after the reboot I can't connect to gui. I can start the vm's using the command line as in: qm start ... but I can't connect to them over the network. I can ping ip...

My proxmox install used two drives in a zfs pool as the storage system, but one drive was starting to fail. I bought a new, larger drive, backed up the VMs and copied /etc/pve. I swapped out the dying drive for the new one, and reinstalled proxmox. Then things went south. I added the second...

I'm really hoping I haven't destroyed my data with this screwup...Specs for the system are: Ryzen 7 3700x Asrock b550m-c 32gb ddr4-3200 LSI 9211-8i with IT firmware Intel X540-T2 -> This is the NIC i was trying to add before all of this went downhill Proxmox installed on 2 raidz1 1TB ssds...

Hi, recently, one of my hosts died since the drive went corrupt. I installed Proxmox to a new Drive and was able to restore the VM configurations and else use a backup I had luckily done a month before the drive went corrupt. All of my VMs are now back up and running, but I had to manually...

Hi, I am freaking out a bit, because this happened when I need it the least ... A few month ago, I turned off my last raspberry pi and migrated everything to PVE. For that purpose built a server using the following (brand new) components: - Intel NUC 12 Pro Kit NUC12WSHI70Z(Intel Core i7 ...

On Sunday I manually shut down my proxmox ve server for a planned power outage. During this process I did the following: 1: shut down my samba file server container (#107) 2: deleted an old test VM (VM105) -there was an option to included purging unreferenced disks, I wanted to recover the...

Hello I cannot recover some VMs from PBS to Proxmox PE VM has couple of GBs, for example 64GB, my pve/data has 1,6TB free space. But recovery job is stopped for example after 24% and it ends with following error. It looks like PE think the VM is 7,5TB big and then of course. It can not fit to...
