This is really cool. On first glance the code is both huge and respectably commented. I wonder if / when someone will attempt a port, and if any layers will be violated. (Ducks and covers! ;) )

Also, I wonder if there are Veritas IP issues. I saw in some Compaq docs that LSM was VxVM derived, so I wonder if pieces are missing? Regardless, I heard a rumor that VxVM would be open sourced. Since hell just froze over here, who knows?

Would love to dig around all day. Too bad I have a real job! ;)

LSM is/was a layer that sits beteen ADVFS and the block I/O device files.They are separate products. You could always run ADVFS directly on the partition. If you wanted RAID features you use LSM (Logical storage manager) in between.
There should not be any Veritas code in ADVFS

Yep. Should have read the hitchhikers guide they posted before I posted. I had always thought they were tightly integrated, but not so. Of course, I only ever used Tru64 as an end user...
