hi,

HP has released AdvFS, a file system that was developed by Digital
Equipment Corp
and continues to be part of HP's Tru64 operating system.

More info and code at: http://advfs.sourceforge.net/

so much to do, so little time.

Wow! That's awesome. I discovered it in 1999 and 9 years later, it probably
remains the most advanced FS I encountered. That was a major reason I was
sad to see Digital Unix die.

Kudos to HP for explicitly releasing under GPLv2 to make it Linux-compatible!

Its good to hear from AdvFS fans. :-)

In case its not clear, this is a GPLv2 technology release, not an actual
port to Linux. We're hoping that the code and documentation will be
helpful in the development of new file systems for Linux that will
provide similar capabilities, and perhaps used to make tweaks to
existing file systems. We'll get the tests posted soon.

The docs alone are great, I haven't even gotten to the code yet ;)
Thanks to HP for all of this.

That's something I missed in the press release... what is so advanced
about AdvFS? What is the killer feature?

You have to see this in context. Incidentially, I also got in contact with True64 and AdvFS at about the same time after long IRIX experience. At that time AdvFS definitely was advanced to anything available on True64. Comparable to the situation with other proprietary OSes - journaled high-availability filesystems just were not the standard. Neither was a fully integrated volume manager...

Wheter AdvFS is still really "advanced" I cannot say, but good that the internals are now open. If only to learn from.

Btw. XFS on IRIX was the really advanced FS at that time, of course :-)

Cheers
Martin

Automatic storage pool resizing would be the killer feature I would want.
Especially advanced Windows users (yes, well, that's my observation)
tend to create lots and lots of partitions and of course having one
filled up means you either need to improvise or undertake a partition
resizing (the latter of which is always a bit risky).
