Hi List, Can you suggest a way of cryptographically verifying the content of a btrfs subvolume, besides the naïve approach, of running a cryptographic hash function on the output of btrfs send?
Back in 2014, an RFC patch was sent to allow using sha256 instead of crc32c for checksumming. (https://patchwork.kernel.org/patch/5363311) It was not merged. Had it been merged, one could just check the return value of btrfs scrub, instead of checksumming the whole btrfs send output, correct? Regards, Leonid. ___
