snapshot

I setup a new 5.3 two-node cluster and created some CT on a local LVM volume. When i backup a CT to a NFS storage it starts, says it cannot do snapshot and continues with suspend mode but never finishes. The node or better the PVE gui gets unresponsive, all NFS mounts hang and also a reboot is...

Hello, i have notice this issue: if i try to rollback to a zfs snapshot when proxmox5 replication are active, i can't, it's fail with error: more recent snapshot. So i have to stop and remove replication.. and finally rollback. I'm wrong or is it the only way to rollback ? Thanks!

Hello, what is the differences between doing a command line zfs snapshot and qm snapshot vmid ? Thanks!

Servus, ich plane, für ein Kleinstprojekt bei einem Kunden erstmals Proxmox statt VMware einzusetzen. Allerdings habe ich noch keine Ahnung, wie ich am Besten die Backups der 2-3 virtuellen Maschinen (1x Windows, 1x Ubuntu Server) vornehme? Die Datenmengen sind sehr überschaubar, sodass ich auf...

Hello, is Kvm (qemu) vps ZFS snapshot consistent without qemu agent installed on guest ? There are differences between a snapshot of an LXC vps and a KVM vps using zfs ? Thanks!

Hello to all. I have used Proxmox since 3.4. the advances in the platform are definitely exciting to see! We are using zrep to sync zfs volumes to a non cluster machine at this time. Thanks to Brown @ bolthole for his code. It works well. However I have a hankering to use the cluster features to...

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...

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...
