The client requests an IP address, and tftp image to boot from, both are provided by the DRBL server. The client boots the initial RAM disk provided by the DRBL server via tftp, and proceeds to mount an nfs share (also provided by the DRBL server) as its root (/) partition. From there, the client boots either the linux distribution on which the ...
Unionfs can also be used to create a single common template for a number of file systems, or for security reasons. It is sometimes used as an ad hoc snapshotting system. Docker uses file systems inspired by Unionfs, such as Aufs, to layer Docker images. As actions are done to a base image, layers are created and documented, such that each layer ...
This differs from the traditional NFS server which holds the names of files and their data under the single umbrella of the server. Some products are multi-node NFS servers, but the participation of the client in separation of meta-data and data is limited. The NFSv4.1 pNFS server is a set of server resources or components; these are assumed to ...
Some researchers have made a functional and experimental analysis of several distributed file systems including HDFS, Ceph, Gluster, Lustre and old (1.6.x) version of MooseFS, although this document is from 2013 and a lot of information are outdated (e.g. MooseFS had no HA for Metadata Server at that time).
Hexdump of the Initialization / Handshake between a Network Block Device client and server. On Linux, network block device (NBD) is a network protocol that can be used to forward a block device (typically a hard disk or partition) from one machine to a second machine.
Filesystem in Userspace (FUSE) is a software interface for Unix and Unix-like computer operating systems that lets non-privileged users create their own file systems without editing kernel code. This is achieved by running file system code in user space while the FUSE module provides only a bridge to the actual kernel interfaces.
Some spare blocks in the GFS journals are used to create the (very small) per_node files required by GFS2 during the update process. Most of the data remains in place. The GFS2 "meta filesystem" is not a filesystem in its own right, but an alternate root of the main filesystem. Although it behaves like a "normal" filesystem, its contents are ...
SFTP provides secure file transfer from a remote file system. While SFTP clients can transfer files and directories, they cannot mount the server's file system into the local directory tree. Using SSHFS, a remote file system may be treated in the same way as other volumes (such as hard drives or removable media). [6]
