Less known Solaris features: SamFS
Tuesday, March 25. 2008
Pheewww ... i´ve finalized my SamFS tutorial, a long text. SamFS is the hierarchical Storage Management Filesystem from sun. Several new concepts, so you have to explain some theory before getting to the shell:
- Part 1: Introduction.html
- Part 2: The theory of Hierarchical Storage Management
- Part 3: The Jargon of SamFS
- Part 4: Installation of the packages
- Part 5: Configuring a SamFS filesystem
- Part 6: Configuring disk archiving
- Part 7: Working with SamFS
- Part 8: Usecases and future directions
- Part 9: Conclusion

Great writeup!
Thanks for taking the time to providing this very useful introduction to Sam-FS.
Any chance of you doing a writeup on QFS as well?

Thanks for the nice introduction. I am particularly interested in the network usages. It might be interesting to use samfs with clusterfs (when it finally gets some replication features) or something like that.
The fact that calls to backends that are not directly available (created for tapes) block makes it not too well suited for use as a storage for laptops that would have access to the backend only when they are connected.
Just trying to think of more uses.

Thanks for writing this up. This helps a great deal for getting started with SamFS.
The only thing that is missing was how to setup the diskvols.conf file (/etc/opt/SUNWsamfs/diskvols.conf), in part 6.
Thanks again, this really helps how samfs works.

Okay, okay ... as several people have asked for it ... but you know my opinion.
Hierarchical storage management is really useful to offload seldom used data to cheaper media like tape while keeping them in access by a filesystem. SamFS is such a filesystem. Your normal disks are just a cache, the data resides on tapes, magneto-optica
