gzip for ZFS update
The other day I posted about a prototype I had created that adds a gzip compression algorithm to ZFS. ZFS already allows administrators to choose to compress filesystems using the LZJB compression algorithm. This prototype introduced a more effective — albeit more computationally expensive — alternative based on zlib. As an arbitrary measure, I used [...]
a small ZFS hack
I’ve been dabbling a bit in ZFS recently, and what’s amazing is not just how well it solved the well-understood filesystem problem, but how its design opens the door to novel ways to manage data. Compression is a great example. An almost accidental by-product of the design is that your data can be stored compressed [...]
