What was Taft's and why?许多其它的文件系统,包括BTRFS和ZFS是不能这样做的。
Many other filesystems including BTRFS and ZFS cannot be resized.
FCoE: the next generation of storage.我的服务器重建,部分1-与Ubuntu,一个模糊的介绍与btrfs.
My server rebuild, part 1- with Ubuntu,and a vague intro to btrfs.Btrfs-一个基于B树的文件系统,甲骨文公司创造。
Btrfs- A file system based on B-Trees, created by Oracle Corporation.这里有两个优秀的文件系统可以做这个工作:ZFS和Btrfs。
There are two excellent file systems that can do this job:ZFS and Btrfs.Btrfs是由Oracle开发的一个文件系统,挑战Sun的ZFS。
Btrfs is a file system developed by Oracle to challenge ZFS from Sun.RHEL目前的技术预演是ext4,而现在则根本不支持BTRFS。
Ext4 is a technical preview in RHEL today and BTRFS is not current supported at all.BTRFS是非常新的,仍处于开发状态,所以我不建议使用它。
Btrfs is very new and is still under heavy development so I don't recommend using it yet.参见下面的Q以及btrfs-qgroup(8)手册,以了解更多关于btrfs的配额组(quotagroup)的概念。
See btrfs-qgroup(8) for details about the btrfs quota group concept.Btrfs不断地增强,这次在文件系统中加入了优化的回写处理。
Btrfs continues to be enhanced, this time with optimized write-back handling within the file system.如果满足btrfs文件系统的先决条件,会输出Supported,否则会输出:.
If the prerequisites for the Btrfs file system are met, the supported is output, or the output is:.BTRFS最终可能会给ZFS等带来更多威胁,但是目前还没有最后成型。
BTRFS may eventually pose more of a threat to ZFS and others, though it has yet to be finalized.随着ext4和BTRFS的成熟,我们将了解他们中的哪一个最适合于特定的企业工作负载。
As ext4 and BTRFS mature, we will learn which of them are best tailored to specific enterprise workloads.Btrfs也很棒,但是你首先需要对/var/lib/docker使用的硬盘进行分区。
Btrfs is great too but you need to partition the disk you will use for/var/lib/docker as btrfs first.Bethencourt指出,Btrfs已经为SUSELinuxEnterprise做好准备,可以用于生产用例。
Bethencourt noted that Btrfs is already available for SUSE Linux Enterprise, so it is ready for production use-cases.BtrFS的开发者们许诺过,该文件系统是当前其他文件系统的新一代替代者。
The developers of BtrFS have promised that this file system is the next-gen replacement for other file systems out there.从文件系统的角度看,RHEL7的用户可以在ext4,xfs和Btrfs之间进行选择,用于启动和数据使用。
From a filesystem perspective RHEL 7 users will be able to choose between ext4,xfs and Btrfs for both boot and data usage.虽然Btrfs还在使用日志树,但这个树仅仅是为了加快fdatasync/fsync的速度。
Although Btrfs still has a journal-like log tree, it is only used to speed-up fdatasync/fsync.安装完成之后使用如下apt-btrfs-snapshot命令检查是否支持btrfs快照的创建:.
After the installation is complete,use the following Apt-btrfs-snapshot command to check that the creation of the Btrfs snapshot is supported:.Btrfs可用于构建大型企业存储系统,拥有在线修复和简化维护等特性。
Btrfs can be used to build massive enterprise storage systems, with features like online repair and simplified maintenance.它基于流行的开源技术,例如Btrfs文件系统和使在软件容器内部署应用程序可自动化的Docker。
It is based on popular open-source technologies, such as the Btrfs file system and Docker for automating the deployment of applications inside software containers.Btrfs当然值得尝试、但要在桌面Linux上完全取代ext4可能还需要一些时间。
Btrfs is definitely worth looking into, but a complete switch to replace Ext4 on desktop Linux might be a few years away.比如ChrisMason,Facebook的软件工程师,同时也是Btrfs(发音为ButterFS)的维护人员之一。
For instance, Chris Mason,a Facebook software engineer and one of the Btrfs(pronounced Butter FS) maintainers, explained how Facebook uses this file system.Btrfs目前也是技术预览并提供Ext4(目前Linux默认)没有的新的回滚和快照功能。
Btrfs is also currently in technical previews and provides new rollback and snapshotting features that Ext4(the current Linux default) does not.我们内核团队的21位工程师对主流Linux做出了600多份贡献,包括cgroups2、MD/RAID5缓存、eBPF、btrfs和缓冲写回修复。
Twenty-one engineers in our kernel team made more than 600 contributions to mainline Linux, including cgroups2, MD/RAID5 caching,eBPF, btrfs, and buffered writeback fixes.Btrfs-一个寫入時複製文件系统,甲骨文公司(Oracle)于2007年面向Linux宣布并采用GNU通用公共许可证(GPL)发布。
Btrfs- is a copy-on-write file system for Linux announced by Oracle in 2007 and published under the GNU General Public License(GPL).Btrfs基于GPL许可,由于不是十分稳定,虽然许多Linux发行版都对其进行了集成,但并不作为默认文件系统进行使用。
Btrfs is licensed under the GPL and is not very stable, although many Linux distributions are integrated, but are not used as default file systems.Btrfs增强继续存在于版本3.4中,并且还有一个新的数据恢复工具,可用于从损坏的btrfs文件系统提取文件。
Btrfs enhancements continued in release 3.4 with a new data-recovery tool(btrfs-restore), which can be used to extract files from a damaged btrfs file system.Btrfs是一个Linux中的新的写时复制(copy-on-write(COW))的文件系统,目的是实现高级功能的同时着重与容错功能,修复功能以及易于管理。
Btrfs is a new copy on write(CoW) filesystem for Linux aimed at implementing advanced features while focusing on fault tolerance, repair and easy administration.
