This is deemed safe since 3.2 kernels. Corruption has been reported before that, so you want a recent kernel. The reason was improper passing of device barriers that are a requirement of the filesystem to guarantee consistency. > And clearly encryption is not possible if you need snapshots. Snapshots don't come into this at all: btrfs doesn't care where the block devices it's on come from. Things like dm-crypt show btrfs (or whatever filesystem you put on it) a decrypted view of the device. -- 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
