snapshot

So I recently made a cron job that, every 6 hours, would take a snapshot of every VM (just to have faster and up-to-date backups to protect against user error). Everything is flawless and I have yet to encounter any issues. BUT there is one hiccup that is getting rather annoying: the cluster...

I have an LXC container running on a Ceph pool. It's running just fine. It has a nightly backup set up to run. For the last week or so, the backup keeps on failing with: vzdump 60180 --mailnotification always --mode snapshot --mailto someone@example.com --quiet 1 --storage nas01-backup-7x...

Dear Forum, the snapshot 'Secure' shows the state 'delete'. I tried to delete that snapshot, but I get: qemu-img: Could not delete snapshot 'Secure': Can't find the snapshot TASK ERROR: command '/usr/bin/qemu-img snapshot -d Secure /var/lib/vz/images/100/vm-100-disk-1.qcow2' failed: exit code 1...

I am currently using ZFS as my default storage solution for a one node PVE cluster. Each VM gets a RootFS- and SWAP-Volume from two different parts of the main pool. If a VM stores data (e.g. personal cloud), it gets an additional ZFS volume by path, so I will pass a block device like...

Hello, what is the best way to replicate to a separate ZFS volume ( on the same server ) a VM disk + Snapshot? Thanks!

I have a situation where a snapshot reversion for a container (rbd backed) is failing with the error "unable to read tail (got 0 byte)" in the tasklog. doing a manual reversion using rbd snap works fine. proxmox-ve: 5.1-42 (running kernel: 4.15.3-1-pve) pve-manager: 5.1-46 (running version...

Hi, We have an issue with virtual machines crashing during snapshot creation, can you please advise how to resolve this issue? Our system: proxmox4.4 ceph 10.2.7, backup - eve4pve-barc,5 servers, 30 OSDs. In the last month 3 virtual boxes on different nodes crashed with the same symptoms. We...

Hello, what is the best practice to remove old zfs snapshot ? Can i remove only strating from newer or can i start olso from older ? Can i remove a random snapshot without corrupt others ? Can i remove all VM snapshot using one commant line ? Thanks!

Hello, on my server i can't do new snapshot: ----------------------------------------------------------------------- root@nodo5:~# zfs snapshot rpool/KVM/vm-105-disk-1@snap1 cannot create snapshot 'rpool/KVM/vm-105-disk-1@snap1': out of space root@nodo5:~# root@nodo5:~# zfs list -t all NAME...

Ich habe am 29.3. gegen 9:12 Uhr einen Snapshot gelöscht um Platz zu schaffen, dabei gab es einen Fehler, diesen habe ich nicht weiter beachtet, nur gesehen dass in der WebGUI wo ich diesen Löschen wollte, dieser noch vorhanden war. Daraufhin beschloss ich einen Tag später den Host neuzustarten...

When backing to external usb drive and cancel backup before completion all space occupied during backup process is reset like it was cache. However once backup successful all occupied space remaining on local zfs and there is no way to remove it. Any idea?

Hi there, after running for about two years, one of my VMs came up with a strange behaviour, which led to a total desaster: Preamble: one VM noticed me about an issue with its filesystem and suggested that i should run 'fsck' to repair it. After rebooting the VM, the filesytem only started in...

Hi! I have a server with proxmox installed. I set up the dayli auto snapshot. Today I try to rollback to a snapshot but it failed, because of my disk full. I remove a few snapshot, but my CT doesn't start. I try to rollback, but failed also: lvremove 'pve/vm-100-disk-1' error: Failed to find...

Hi, I can not create snapshot for some LXC. The button is disabled. What could be the reason for this?

Good day, I have a use case (SKS database "offline" dump), where I'd need to snapshot, clone and mount one of the mount points for an LXC container. The newly mounted snapshot/clone, will then be used to generate data dump/export. Before hacking config files, any advice to do it with in the...

Hi all Happy New Year to everyone. When we do a Snapshot it is held on the same drive as the VM is located. Is there a way to View a previous rollback date without actually rolling back. IE. we just want to recover a couple of files from a previous day?? And What happens with Snapshots in our...

I have a weird problem with specific containers failing to snapshot; the end result is that scheduled vzdump tasks effectively fail and disallow any further vzdump jobs until manually killed. The thing is, if I MANUALLY take a snapshot using rbd snap create it works fine- its only via api that...

Hello, I'm creating VM's from backups off a Proxmox node that is not part of my cluster but I noticed when restoring these backups that snapshots are not included. Is there a way to create VM backups that include the snapshot as well?

I have a Proxmox server version 5.1-35 (kernel: 4.13.4-1-pve) and can't create a container snapshot, the button shows greyed out. I do can create VMs snapshots. This problem also happens on another Proxmox server version 4.4-13/7ea56165. Maybe this is a new change or simple you cannot create...

Hello everybody, i have a Proxmox 5.1 server running and i want to remove snapshots of a VM that makes a lot of trouble. I tried to do it with the eve4pve-autosnap clean function but my server crashed and now i have a lot of snapshots in proxmox without existing ZFS snapshots. How can i get...
