    Using bind mount point with NextCloud LXC on ZFS (or alternate options?)

    The title sums it up, more or less. I'm relatively new to ProxMox and self-hosting in general. I basically want to share NextCloud folders with other LXCs, and think I ran into a case of trying to figure out too many things all at once, and thought I'd ask for advice, just to be safe. I'm...

    [TUTORIAL] FabU: how to select the correct disk, or: what’s in a (device)-name?

    The different names for disks may lead to confusion. I show some different names to specify the "right" device. Why is this important? Well..., the obvious thing is that “zpool create” will destroy the old content. You will lose any data stored on it. And the “classic” names like “sda” may...

    As a new user to proxmox (coming from TrueNAS Scale), I made a bunch of mistakes that cost me an aggravating week of time/effort.

    Replacement HDD gets here tomorrow. In the mean time I'd like to save the mirrored good drive from working overtime to resilver the failing drive. I also don't understand how to swap the new drive with the old drive, since I don't have any open drive bays to add the new drive to the pool...

    Hi there, I'm currently running Unraid in a VM on Proxmox and passing through the SATA controllers, as well as one NVME drive on my Motherboard. I started using Unraid as an easy method to use disks of different sizes and have a cache in front. But over time, came to realize that the vanilla...
