Heres a bash script which I think does something simular but uses zfs diff to find files that differ… just a hack

pass snapshot name as first argument

#!/bin/bash
datasetANDsnapshot=$1

snapshot=$(echo $datasetANDsnapshot | cut -d’@’ -f 2)
datasetName=$(echo $datasetANDsnapshot | cut -d’@’ -f 1)

echo “Looking for differences for ” $datasetName”@”$snapshot

for f in $(zfs diff $datasetANDsnapshot | grep “^M” | awk ‘{print $2;}’)
do
echo “+++++++++++++++++++”
echo “File modified from ”
diff $(zfs get mountpoint -o value $datasetName -H)”.zfs/snapshot/$snapshot$f” $f
done

Will its a very old post/script… but looks usefull still

Somewhere in the code

zfs get mountpoint -o value $datasetName -H

Would substitue the right mount point… don’t know where yet

Chris: Thanks for pointing that out, I wasn’t considering that the mountpoint of the FS can be different than the name, I’ll have to work on an update, thanks!

great script, but it does not work quite well for me…
# zfs list
mypool/d 270G 3.69G 145G /d/d2
mypool/d@2006_10_month 3.72G – 123G –
I have mountpint as /d/d2, your script is looking for /mypool/d, so if I create symbolic link /mypool/d pointing to /d/d2 then it works.

anyway great tool…

Very cool. You should submit it to Sun’s bigadmin site (www.sun.com/bigadmin)
