  1. zfs snapshotting and backups in lxc container?

    Hello, I am planning on using sanoid/syncoid or something similar to perform snapshots and backups of my zfs pool(s). I understand that I can add packages and/or do whatever I need in the host debian environment, but I was wondering if I can do the same inside an lxc container with the host...
  2. Best way to access files on host

    Hi, There's something I think I'm doing wrong. I have Proxmox on a host with a ZFS pool inside. How do I best access the files on the ZFS volumes from containers? I have read suggestions to serve the files over NFS directly from the host. This seems like a round-about way (ZFS > host > NFS >...
  3. Sync not copying all snapshots

    Hello, I had a VM with the ID 135 that was re-deployed under the ID 105. To keep the backups from the old machine, I did the following on my datastore: mv vm/135 vm/105 I then switched the backup job in Proxmox VE to backup the new VM 105. This seems to work as all my previous backup from my...
  4. Snapshots naming scheme

    Hello, We have a backup schedule for PBS that run at 23:00 EST everyday. The issue we have is that the naming scheme for the snapshot seems to be built using a different timezone. An exemple would be if we backup a VM the 21 of May at 23:00 EST, the snapshot name would be 22 of May 3:00 This...

  7. Shared storage between CTs without bind mounts to have VE Snapshots?

    I've been reading through the wiki and the various posts, but I am beginning to have the distinct understanding that having sharing files/folders between CTs in unprivileged containers without bind mounts is not something that is available? I am currently running two ZFS pools and I have a...
  8. [SOLVED] Inconsistency Grub Menu vs. /boot/grub/grub.cfg

    Hello! I have a question regarding the content of Grub Menu vs. /boot/grub/grub.cfg. In my case the content is inconsistent. And this is causing an issue with booting a BTRFS snapshot, because the required snapshot won't boot with the options displayed in Grub Menu. I'm running these software...
  9. Feature Request: improved snapshot

    Hi, Proxmox doesn't permit to take a snapshot when your VM has a passthru device attached, which sounds rational since snapshots by definition "freeze" (save) the whole state of the VM and that's impossible for non-emulated hardware. BUT there are some scenarios where I think it's still useful...
  10. The Hassle (and Joy) of Snapshots in a ZFS Cluster

    I’m running a fairly active but small budget Proxmox cluster for circa one year now. Meaning depending on the current project workload it only consists of 3-4 nodes and uses ZFS due to its replication capabilities which allow nearly HA-like failover times (5 to 10 minutes in my case) with a...
  11. Unterstanding how snapshots under LVM Thin-Volumes work

    Hello, I work with Proxmox 5.2 and LVM Thin-Volumes. I create a couple of snapshots from a windows test-vm and wondering how it worked. A normal thin snapshot under LVM2 used the same size as the original thin-volume has. In my case the thin-lv has 32GiB, so the snapshot would become also...

    Hallo, bringt Proxmox eine Methode mit, um alle laufenden VMs automatisch zu snapshotten (wobei nur X vorgehalten werden und ältere autom. gelöscht werden, quasi das "automysqlbackup" für VMs)? Gruß und Danke!
  14. Sortierung der Ausgabe von "qm listsnapshot"?

    Hi, gibt es eine Möglichkeit, die Ausgabe von "qm listsnapshot" chronologisch sortiert anzeigen zu lassen? Aktuell scheint mit die Ausgabe nicht sonderlich übersichtlicht, bspw. sieht eine akt. Ausgabe bei mir so aus: # qm listsnapshot 104 snap3 snap2 no-description snap2 snap1 no-description...
  15. adventures with snapshots

    I have a new problem (well, it could be old and I just noticed it.) I have a number of containers that show any number of snapshots but when I look at the disk those snapshots dont exist. Example: pvesh get /nodes/sky12/lxc/16980/snapshot 200 OK [ { "description" : "Automatic snapshot...
  16. ZFS usedbysnapshot is off by a hundred gigabytes

    Hello, I have a couple of Proxmox 4.4 deployments out in the wild. On occasion, one of them will have their "usedbysnapshot" field grow to incredible sizes. If I do a zfs get all on the vdev, it's showing usedbysnap is 279G. I've listed out all of the snapshots, there are 337 hourly snapshots...

Daraufhin beschloss ich einen Tag später den Host neuzustarten...
