btrfs also hasn't even reached alpha level stability yet. An unexpected powerdown often means "restore from backups" at this point.

- simoncion 11y agoI've been using btrfs in my laptop on my OCZ Vertex LE [0] since that drive was shipping with the data-eating v1.0 firmware. [1] I'm also running it on my desktop, and in a force-compress multi-device firewire-attached configuration for a multi-TB Postgres tablespace. It has been many, many years since I've run into a data-loss issue of any kind, despite unexpected power-downs or other failures. Now... if you're using Kubuntu 15.04[3], with btrfs as your root volume, know that system lockups that require a hard reset may well do something to the log that makes mount hang. Do this [4] if your "task is hung" backtrace looks something like the one in the wiki page, then btrfs-zero-log is the thing you need to do. [0] The drive is still going strong and error-free, too! :D [1] This drive is what taught me to ALWAYS upgrade the firmware in your SSDs, ASAP. :P [3] Christ, what a nightmare this version is! :( [4] https://btrfs.wiki.kernel.org/index.php/Btrfs-zero-log https://btrfs.wiki.kernel.org/index.php/Btrfs-zero-log
