Btrfs Brings Experimental Remap-Tree Feature & More In Linux 7.0 (www.phoronix.com)

Among the pull requests merged today on this first day of the Linux 7.0 merge window are the many Btrfs file-system feature updates.

David Sterba sent in the Btrfs feature pull in advance of the Linux 6.19 stable release and thus among the early merges for kicking off the Linux 7.0 cycle. There aren't any noted performance optimizations specifically this cycle but a lot of other feature work some of which may help performance like enabling direct I/O for larger block sizes when greater than the kernel's page size.

How is BTRFS these days? I've been using XFS for so long just because of my soft spot for IRIX.

Edit: Thanks for the replies. I'll find an unused box and check it out.

I love it. Connected to snapper tools and it's saved me several times. I can boot to any snapshot in grub, and it's been way more reliable than Window's Restore Points ever have been.

I use it because it has native compressio and also an entire incremental backup tool built in (btrfs send/receive can throw snapshots of a filesystem across networks)

Although my actual daily driver is FreeBSD with ZFS

I'm daily driving it on my main desktop and several laptops with full disk encryption and zero issues, although I am not a power user of some of the complex functions btrfs offers, I just slap it on a whole disk and dump all my files into one big partition and that's pretty much good enough for me. I should try subvolumes at some point I guess, IDK.
