FUSE文件系统

耗尽温柔 提交于 2020-01-24 13:54:12
用户空间文件系统(Filesystem in Userspace,简称FUSE)是操作系统中的概念,指完全在用户态实现的文件系统。目前Linux通过内核模块对此进行支持。一些文件系统如ZFS,glusterfs和luster使用FUSE实现。 Linux用于支持用户空间文件系统的内核模块名叫FUSE,FUSE一词有时特指Linux下的用户空间文件系统。 文件系统是一个通用操作系统重要的组成部分。传统上操作系统在内核层面上对文件系统提供支持。而通常内核态的代码难以调试,生产率较低。 Linux从2.6.14版本开始通过FUSE模块支持在用户空间实现文件系统。 在用户空间实现文件系统能够大幅提高生产率,简化了为操作系统提供新的文件系统的工作量,特别适用于各种虚拟文件系统和网络文件系统。上述ZFS和 glusterfs都属于网络文件系统。但是,在用户态实现文件系统必然会引入额外的内核态/用户态切换带来的开销,对性能会产生一定影响。 目前Linux,FreeBSD,NetBSD,OpenSolaris和Mac OSX支持用户空间态文件系统。 比较知名的用户空间文件系统: ExpanDrive: 商业文件系统,实现了SFTP/FTP/FTPS协议; GlusterFS: 用于集群的分布式文件系统,可以扩展到PB级; SSHFS: 通过SSH协议访问远程文件系统; GmailFS:

centos使用fuse挂载NTFS

FUSE:用户空间文件系统(Filesystem in Userspace),是Linux 中用于挂载某些网络空间,如SSH,到本地文件系统的模块。 如果装的是双系统,centOS并不支持ntfs分区,所以挂载就成了第一件大事。 1. 安装fuse 网上建议不要用二进制包安装而应该用源代码安装,所以我直接用的源码安装,去这里下载fuse: [url]http://sourceforge.net/project/showfiles.php?group_id=121684[/url] 也可以去这里:[url]http://sourceforge.net/project/showfiles.php?group_id=121684&package_id=132802[/url] (这里的版本比较多) 我是装的fuse-2.8.0-pre1,才成功的。之前试了一下 2.7.4,2.7.3,2.7.2,2.7.1,均以失败告终。 在下载文件包的README里,有编译步骤 即: ./configure make make install modprobe fuse 用比较老的版本的fuse,在./configure时出现错误: FATAL: Module fuse not found. fuse: device not found, try 'modprobe fuse' first FUSE

MFS分布式文件系统搭建

MFS概述 MooseFS是一个具有容错性的网络分布式文件系统。它把数据分散存放在多个物理服务器上,而呈现给用户的则是一个统一的资源。 优势 1、高可靠(数据的多个拷贝被存储在不同的计算机上) 2、通过附加新的计算机或者硬盘可以实现容量的动态扩展 3、删除的文件可以根据一个可配置的时间周期进行保留(一个文件系统级别的回收站) 4、不受访问和写入影响的文件连贯快照 缺点 master服务器不能解决单点故障 MFS的构成 元数据服务器(Master): 在整个体系中负责管理文件系统,维护元数据,目前不支持高可用。 元数据日志服务器(MetaLogger): 备份Master服务器的变化日志文件,当master服务器损坏,可以从日志服务器中取得文件恢复。 数据存储服务器(Chunk Server): 真正存储数据的服务器,服务器越多,容量就越大,可靠性越高,性能越好。 客户端(Client): 可以像挂载NFS一样 挂载MFS文件系统 实验拓扑图 实验环境     服务器                 IP地址              master服务器         192.168.13.128 log日志服务器         192.168.13.129 chunk1服务器         192.168.13.130 chunk2服务器         192.168.13

FUSE filesystem hide from nautilus

问题 I have written a FUSE driver for linux, and when I mount it I get an entry in the nautilus sidebar. I do not want this - the unmount button doesnt even work. I would like to hide this entry in the nautilus sidebar for my mounted fuse filesystem. I dont want to add it to the fstab because running it as root opens security holes. Is there anything I can add to the options line or the code itself to prevent it from showing in nautilus? 回答1: I believe Nautilus will only show those sidebar entries

How do I check whether a fuse folder is present

◇◆丶佛笑我妖孽 提交于 2019-12-24 15:10:16
问题 I have a folder mounted on the server that points to an sftp site. I need to check via php whether we can see the folders inside it. I tried file_exists("/path/to/the/mount/folder"); but its returning false (which I kind of expected), I can navigate to it through the file system and using terminal. (also tried is_dir && is_link ) Here's how I mounted it from the shell echo PASS | sshfs UNAME@URL: /path/goes/here -o password_stdin 回答1: This turned out to be a configuration problem. In /etc

Flatpak (flatpak-build) fatal error when building submodules

问题 Following on from here, when using OpenSUSE Tumbleweed I cannot get flatpak-builder to compile submodule dependencies. I first noticed this issue when developing a console application within Gnome Builder using the Vala dependencies Gee and GXml. As a test, I have installed org.gnome.Books.json and issued the following command (as documented here): $ flatpak-builder --repo=repo books-app org.gnome.Books.json The outcome is the same as I observed when developing my own application, the fatal
