Hi Amar! That's great to hear. I'm getting back at using GlusterFS again. Yesterday my web servers started using it again and we'll migrate our e-mail storage to it within 6 weeks. I'll start using the 1.4qa version this week with a new project here. The new BDB storage is the answer to my prayers. I'm developing a spam reputation system here, it will have to handle a few millions of requests per day (~20 million/day), and every request reads and writes a few files (a few per domain name plus a few per IP address). This new BDB storage fits perfectly for me. So, I'm very excited with this new version. Questions: 1 - Will 1.4's unify still need the namespace cache? 2 - If so, can I use the BDB storage for the namespace cache? 3 - Thinking about the database problem I described above, I'll have to open many many files per second. If unify will have to lookup() every server every time it will not scale too much if I add more servers as I will be limited by the lookup() capacity of my worst brick, right? So, talking performance wise, have you thought about the hash scheduler I proposed [1] some time ago that know where a file should be and only asks at right server first? If the file is not found, ask the others. References: [1] http://www.mail-archive.com/gluster-devel@xxxxxxxxxx/msg03520.html Congratulations to all of you.
