because i fail to understand i share my clumsly learnings with proxmox
For some reason or other i wanted to explore how to configure two bridges using a single NIC. Eventually this resulted in the faint hearted decisions to set the gateway of vmbr0 to 0.0.0.0, because who knows, it might just...
I lost a node that contained all of my vm templates. Unfortunately, vm templates are tied to a node, so though the underlying images still exist in my ceph pool, I can no longer use them from the proxmox ui (they can be seen with rbd ls -p <pool>.
What is the recommended approach to resolving...
Hi,
The title says it all, I've mistakenly rm -R /etc/pve/nodes on a quorated PVE 5.4 2-node cluster.
The cluster still runs happily, and pvecm status looks fine and all. But corosync did its job thoroughly removing this directory from the two nodes. I guess the configuration is still in RAM...
Hi everyone,
After a botched removal of a node from a cluster, I'm left with no configs but several lxc disk images in an lvm-thin volume. Is there any way for me to recover it or make a mock lxc config to get those up and running? I do not remember the drive size as the last time I was on the...
Hi,
Please help!
My proxmox can't boot, says no such device: xxxxxxxxxx
I tried lot of things to repair this issues, but i failed.
Now, the import thing is to recovery the files in my vm, but with zfs pool, I can't see the files in VM-Disk (in my case is vm-100-disk-1).
How to mount this...
hi, greetings, i am a proxmox 5.x user and i just built a proxmox cluster with 3 node servers. besides the cluster I also use ceph on proxmox for HA Failove, which aims to make server management easier, especially in terms of server maintenance. now the server is running smoothly with good...
I ran into an issue with my USB-stick installation and was not able to boot from the stick anymore, so I made a new installation of Proxmox into a 32gb ssd-drive and was able to import my old ZFS into this setup using the 'zpool import <name>'-command .
Now however I am unable to mount the old...
Hello! I hvae a very bad situation on one site. PVE is damaged somehow: / directory is clear and some datasets are lost. No backups as usual.... So i was looking for some recovery features of zfs and foung TGX. Some topics i read said that one can import pool with specified TGX. Is this feature...
Hi,
Today there was an unexpected power outage where my servers are co-located, the entire datacenter went dark. Luckily I had fresh backups to simply restore for the most part.
However, I have an issue with one OSD on one server, the OSD is stuck in "active+recovery_wait+degraded" I have...
I have "server1" (10.0.0.1) backing up VM 502 on "server2" (10.0.0.2) with pve-zsync.
I set up the process with:
server1# pve-zsync create --source 10.0.0.2:502 --dest rpool/pve-zsync/daily --verbose --maxsnap 7 --name server2-backup-daily
eventually, server1 blows up and I have to completely...
Hello Guys,
i just restored a backup of a lxc container running on my pve instance. The container has a second .raw data image mounted. After restore the complete data got deleted from the .raw image.
1.) I know there was a "deletes all data of the running vm" window. I'm probably stupid, but...
Situation :
- 3 standalone nodes with VM's on XFS storage
- No Shared storage.
- NFS shares on all 3 nodes to eachother to restore backup files from one node to the other. (added as NFS storage, with backup files only selected in PVE)
Task :
- Introduce new node and setup first cluster node...
Hi there,
since two weeks I'm trying proxmox. My setup was a / SSD using ZFS. And one raid-z2 with 5 WD Red Disks.
Today my SSD crashed and isn't readable anymore. The container data are within my raidz2-pool. Booting with debug installer I could copy the folder of the subvolumes for each...
Hi,
I accidentally deleted one KVM VM and I don't have any backup. Now I'm trying to recover it.
I'm using following procedure to recover.
Step1:
Cloned Proxmox Node 900GB
dd if=/dev/sda of=/mnt/pve/backup/
Step2:
Created a new virtual Proxmox Node restore Proxmox's Drive using dd. New node...
Hi guys! I got into troubles now: I have my Proxmox Installation on two ssd's (raidz mirror) and one hdd that was in separate zpool, and used for backups. I got one VM on that server, with two disks inside it: system disk which was located on raidz ssd's and one volume that was used for backups...
I have a cluster with 3 nodes which act both as vm nodes and ceph storage.
node1: 1 osd, 1tb disk
node2: 2 osd, 1tb disks
node3: 2 osd, 1tb disks
the total is 4,7 usable disks. I created a ceph pool with size 2/ min 1, so I have a single replica of my data. I've now read that it's a bad...
Hi
In Proxmox 4, I added a node with 'pvecm add -force' to an existing cluster.
There were 2 QEMU VMs running on the added node.
Currently the VMs are running but are not present in PVE Manager.
The config files are gone but I have a backup of the VMs, I don't want to restore VMs because they...
After looking around for suitable answers to this particular question I decided to put some of the advice to the test and figure out what the procedure would be in the event my boot drive (ssd) decided to pack it in.
General consensus online and on these forums state that by simply backing up...
I am planning a new Proxmox VE setup and would like to know what current PVE admins are doing for backups. I also need to backup older setups and archive them. Is anyone using BareOS for host baremetal backups? It has current Debian packages and has been mentioned in other forum posts.
