Btrfs – The Filesystem of the Future?
summary
Btrfs is presented as a production-ready filesystem (used by SUSE) supporting volumes up to 16 exabytes and offering in-place conversion from ext3/4 via btrfs-convert, copy-on-write, snapshots/subvolumes, compression and built-in RAID. The demo shows converting ext3 to btrfs, adding and removing a device with btrfs balance, and creating/restoring snapshots with snapper. Warnings include that snapshots consume space and RAID5/6 is unstable, so avoid heavy write workloads such as databases.
