    [SOLVED] Slow ZFS performance

    Understood. I guess I'll re-enable it then :-) Thank you all for the detailed explanations.

    [SOLVED] Slow ZFS performance

    Thank you @LnxBil for the explanation on data corruption in ZFS. It's perfectly clear now. It is indeed more dangerous than I was led to think. Regarding my SSD, I'm confused. I thought I had understood that you said that some drives start at 100% and go down as they wear out. Can you please...

    [SOLVED] Slow ZFS performance

    @aaron, hum... when you talk about losing data, do you mean the last few seconds before an unexpected stop like @LnxBil said above: Or are you talking data corruption? I can live with the former but I definitely don't want the latter. Those 400MB/s are not mine. Mine are probably much slower...

    Store VM application data locally vs in a NAS

    Hi @velocity08, thanks for your answer. It makes sense and this is generally my approach. But the reason I need to store data in my NAS for some of my VMs is because I only have 1Tb SSD in my local storage and that is not enough. Namely for NextCloud and RoonServer. You suggest CIFS but I heard...

    Store VM application data locally vs in a NAS

    I tried that approach and at the time but the shared folder would be mounted bellow each users' root. This way, all users would share it alike, which is not what I want. While I want that shared folder to be the global NextCloud root and then create one folder per user underneath it so that...

    Store VM application data locally vs in a NAS

    Hum... I see... but if I'd want to keep several versions (daily/weekly/monthly) versions of all my VMs I'd be using more space than I currently have, right? And I think I'd be uncomfortable without having "application data" backups (maybe because using an hypervisor is still new to me)...

    Backup of some LXC's failing (Permission Denied)

    Having exactly the same problem here. Did you find anything? Thanks! Update: I noticed that the PVEs were backed up correctly and only the VXC containers failed. Maybe I'll have to use another mode instead of snapshot. I'll give it a try late today.

    Store VM application data locally vs in a NAS

    Hello, I'm new to Proxmox and am still confused on where to store each VM's application data. I've read a lot of threads here but most of them focus on storing the actual VM files while I'm interested in where to store each application's specific data. Example of the data I want to store...
