Hello all. I am looking to be able to verify my zfs backups in the most minimal way, ie without having to md5 the whole volume.
Is there a way to get a checksum for a snapshot and compare it to another zfs volume, containing all the same blocks and verify they contain the same information? Even when I destroy the snapshot on the source? kind of like: zfs create tank/myfs dd if=/dev/urandom bs=128k count=1000 of=/tank/myfs/TESTFILE zfs snapshot tank/[EMAIL PROTECTED] zfs send tank/[EMAIL PROTECTED] | zfs recv tank/myfs_BACKUP zfs destroy tank/[EMAIL PROTECTED] zfs snapshot tank/[EMAIL PROTECTED] someCheckSumVodooFunc(tank/myfs) someCheckSumVodooFunc(tank/myfs_BACKUP) is there some zdb hackery which results in a metadata checksum usable in this scenario? Thank you all!
