James Foronda sent a link to his blog entry about silent data corruption in an Oracle-l discussion. He points out a new file system called ZFS that has self-healing features. I really liked this quote
“Does for storage what VM did for memory”
I read all the slides and it really looks like something cool to try out. It has some features similar to Oracle’s ASM, such as dynamic adding of disks, self balancing etc.
It’s fully transactional, supports snapshots, online everything. Auto striping (not sure how this would work). Very feature rich.
Also extremely simple (from looking at the demo1 and demo2.)
I am really excited. Finally a file system that offers something really special.
I am looking forward to try it out. Currently for SUN only. I wonder when the linux port will show up.
I think it’s called “zfs” (with z – the last letter in the alphabet) because it’s “THE LAST WORD IN FILE SYSTEMS”.
