Unix下针对邮件,搜索,网络硬盘等海量存储的分布式文件系统项目
:Google是当前最有影响的Web搜索引擎,它利用一万多台廉价PC机构造了一个高性能、超大存储容量、稳定、实用的巨型Linux集群。 http://bbs.chinaunix.net/forum/viewtopic.php?t=390949&show_type=old
其分布式分布式文件系统的实现方法,用低成本实现了高可用、高性能集群的方法是并行机设计、开发的一个成功典范,这种严格追求性价比的设计方法值得借鉴。
请大家参与到这一工作中来:)

Ok - Im changing the subject here in an attempt to gather information.
Heres my wishlist:
FreeBSD have a native clustered filesystem. This is different than
shared media (we already can do that over fiber channel, ggated, soon
iscsi and AOE). This would allow multiple servers to access the same
data read/write - highly important for load balancing applications like
web servers, mail servers, and NFS servers.
Online growable filesystem. I know I can growfs a filesystem now, but
doing online while data is being used is *insanely* useful. Reiserfs
and Polyserves FS (a clustered filesystem, not open-source) do this well.
FreeBSDs UFS2 made to do journaling. Theres already someone working
on this.
I believe the above mean that we need a distributed lock manager too, so
might as well add that to my wishlist.
Single filesystem limits set very high - 16TB would be a good minimum.
Vinum/geom (?) made to allow added a couple more disks - be it a real
scsi device, or another vinum device - to existing vinums, so I can
extend my vinum stripe, raid, concat, etc to a larger volume size,
without worrying about which disk is where. I want to stripe mirrors of
raids, and raid striped mirrors of stripes. I know it sounds crazy, but
I really *do* have uses for all this. :)
We currently pay lots of money every year (enough to pay an engineers
salary) for support and maintenance with Polyserve. They make a good
product (we need it for the clustered filesystem and NFS distributed
lock manager stuff) - Id much rather see that go to FreeBSD.
