How could BTRFS and a database "fight" about data recovery? BTRFS offers similar guarantees about data durability etc to other journalled filesystems and only differs by having checksums so that while a snapshot might have half the data that was written by an app you at least know that the half will be consistent.
If you had database files on a separate subvol to the database log then you would be at risk of having problems making a any sort of consistent snapshot (the Debian approach of /var/log/mysql and /var/lib/mysql is a bad idea). But there would be no difference with LVM snapshots in that regard. -- Sent from my Samsung Galaxy Note 2 with K-9 Mail. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
