Not a fan of the coverage of ECC in misunderstandings section.<p>&gt;In any way you can run ZFS and Btrfs without using ECC memory, it&#x27;s not a requirement.<p>Should be:<p>&gt;You can run ZFS and Btrfs without using ECC memory, it is definitely possible, but you shouldn&#x27;t run ANY filesystem without ECC memory.<p>It cannot be stressed enough. Friends don&#x27;t let friends run computers without ECC memory.

With btrfs you can do raid5 data, but use raid1 for metadata. This actually works.<p>This post is testing a known bad thing, that comes with warnings, and confirming that yes the well known problems are real. Waste of time.

&gt; With Btrfs many people immediately use the btrfs check --repair command when they experience an issue, but this is actually the very last command you want to run.<p>Ok. So what&#x27;s the recommended approach? Dump the metadata and start hand culling from there?<p>If the tool doesn&#x27;t exist,it just not yet ready.
