关于BTRFS 与oracle database
在DBA+北京1号群（微信群）里，杨建荣ACE说到了BTRFS 这个文件系统，我是第一次听说，于是就mos了一把，结果还真有。
见如下的mos文章
Supported and Recommended File Systems on Linux (文档 ID 236826.1) 

The current support includes ext2, ext3, ext4 (Oracle Linux 5.6 and later), btrfs  and NFS-based storage systems (e.g. NetApp). 
To be acceptable for database usage, 
the file system must support certain minimum functions such as write acknowledgement,
write-through cache and file permissions. Counter examples are

simple NFS: lacks acknowledge
VFAT: lacks file permissions
btrfs: production-ready with Unbreakable Enterprise Kernel 2 but absolutely not recommended for Oracle RDBMS data files.

看来，BTRFS还是不要用在Oracle database环境中为好。
