The first number is an offset within the file (hex); Lx is a block level where L0 is a data block, L1 is an indirect block just above data blocks, etc; x:y:z is a (top-level) vdev number, a block offset on disk (hex) and a block size on disk(hex); the rest is not as important. The quoted offsets appear to be just below 2TB. -- Andriy Gapon _______________________________________________ freebsd-current@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
