Btrfs in Linux 6.2 brings performance improvements, better RAID 5/6 reliability
But is the RAID handling remotely sane yet? See <a href="https:&#x2F;&#x2F;arstechnica.com&#x2F;gadgets&#x2F;2021&#x2F;09&#x2F;examining-btrfs-linuxs-perpetually-half-finished-filesystem&#x2F;" rel="nofollow">https:&#x2F;&#x2F;arstechnica.com&#x2F;gadgets&#x2F;2021&#x2F;09&#x2F;examining-btrfs-linu...</a><p>It has gems such as:<p>* It won&#x27;t boot on a degraded array by default, requiring manual action to mount it<p>* It won&#x27;t complain if one of the disks is stale<p>* It won&#x27;t resilver automatically if a disk is re-added to the array<p>I think the first is the killer. RAID is a High Availability measure. Your system is not Available if it fails to boot.
