Perform a redacted send with -nv and without, and verify the 26# size estimate is the same as the size of the actual send. 27# 2. Receive an incremental send from the redaction bookmark with 28# -nv and without, and verify the size estimate is the same as 29# the size of the actual send. 30# 31 32ds_name="sizes" 33typeset sendfs="$POOL/$ds_name" 34typeset clone="$POOL/${ds_name}_clone2" 35setup_dataset $ds_name "-o compress=lz4" 36typeset tmpdir="$(get_prop mountpoint $POOL)/tmp" 37typeset size=$(mktemp $tmpdir/size.XXXX) 38typeset size2=$(mktemp $tmpdir/size.XXXX) 39 40log_onexit redacted_cleanup $sendfs $clone 41log_must zfs clone $sendfs@snap $clone 42typeset clone_mnt="$(get_prop mountpoint $clone)" 43log_must rm -rf $clone_mnt/* 44log_must zfs snapshot $clone@snap 45log_must zfs redact $sendfs@snap book $clone@snap 46log_must eval "zfs send -nvP --redact book $sendfs@snap | awk '/^size/ {print \$2}' >$size" 47log_must eval "zfs send --redact book $sendfs@snap | wc -c >$size2" 48read -r bytes1 < $size 49read -r bytes2 < $size2 50[ "$bytes1" -eq "$bytes2" ] || \ 51 log_fail "Full sizes differ: estimate $bytes1 and actual $bytes2" 52 53log_must zfs snapshot $sendfs@snap2 54log_must eval "zfs send -nvP -i $sendfs#book $sendfs@snap2 | awk '/^size/ {print \$2}' >$size" 55log_must eval "zfs send -i $sendfs#book $sendfs@snap2 | wc -c >$size2" 56read -r bytes1 < $size 57read -r bytes2 < $size2 58[ "$bytes1" -eq "$bytes2" ] || \ 59 log_fail "Incremental sizes differ: estimate $bytes1 and actual $bytes2" 60 61log_pass "Size estimates of redacted sends estimate accurately." 62
