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。
