Hello
This is feature is primarily used by HSM, internally, but is not limited to.
data_version is a number computed from each OST objects the file is made of.
Two different values for data_version mean the file content has changed.
Two identical values mean the content is identical. There is n
This is just a guess - could it be related to ZFS backends? Allowing for
snapshots etc.

Greetings List!
What is the number from the command "lfs data_version $filename " telling
me?
I do not see "data_version" documented in lfs -h, man lfs, nor in lustre
manual..
I do know that if I have a zero-length file my robinhood scan of my Lustre
mount point indicates that "lfs get_version"
