Sun Solaris, OpenSolaris It seems like we're really on the subject of filesystems and related technology the past few days. We had an interview with the man behind BeServed, an item on WinFS' current status, and now we - possibly - have news on ZFS coming to Linux. Possibly, because it's all speculation from here on out.

I use ZFS on 1GB RAM

Member since:

and a P4@2.4GHz. From my ZFS raid, I get like 20MB/sec. I am told it is slow because ZFS is 128bit and it doesnt like my 32 bit cpu. But everything works rock solid. I use OpenSolaris.

Another guy gets 120MB/sec from his ZFS raid, with 64bit cpu - on his blog. It seems that 64bit cpu is beneficial for getting speed.

But the killer feature of being able to rollback the /root to an earlier state, to choose from which snapshot to boot from via GRUB, etc, is really useful. And the snapshots work on a bit level, is is impossible to write to an snapshot. If you destroy a snapshot, every bit gets destroyed.

And, ZFS is so simple too. Ive heard to set ut a raid with linux + lvm is like 25 command lines with difficult syntax. With ZFS it is 2 simple commands. A server enterprise file system like ZFS is very suitable to the average joe, because it is so easy to administer and use. All other raid alternatives are difficult. With ZFS you dont have to make partitions in advance, they grow dynamically and it is light weight as creating a directory. Every user will have a dedicated partition on his own.

Like LaTeX and MS Word, all Word supporters says they can do everything with Word what can be done with LaTeX, but once they try LaTeX - they love it. Just try ZFS and you will change your mind.
