Not proxmox-specific, but I've been using btrfs on my servers and laptops for the past 6 years with zero issues. The only times it's bugged out is due to bad hardware, and having the filesystem shouting at me to make me aware of that was fantastic.

The only place I don't use zfs is for my nas data drives (since I want raidz2, and btrfs raid5 is hella shady) but the nas rootfs is btrfs.

oh good, that's just reader-mode mangling the TOC. Those are supposed to be clickable links to jump to the relevant section. Firefox's reader-mode does a better job by not rendering the TOC at all. Thanks for the scare hehe

Hey! Website author here :>
Curious about the SEO garbage you're seeing because that's not coming from me. Could you post an example? Are you using any shady VPN's or anything like that?
