Implementation Status What works today? Some details How to handle Linux continuing to extend APIs? Wireshark and Tracing Linux > POSIX Currently huge number of syscalls! (try “git grep SYSCALL_DEFINE” well over 850 and 500+ are even documented “man syscalls” FS layer has 223). Verified today vs Only about 100 POSIX API calls 513 syscalls with man pages! +12 just since last year’s SDC! Some examples of new fs ones from past 9 months ... Syscall name Kernel Version introduced io_uring_enter 5.1 io_uring_register 5.1 io_uring_setup 5.1 move_mount 5.2 open_tree 5.2 fsconfig 5.2 fsmount 5.2 fsopen 5.2 fspick 5.2 Repeating an old slide ... Remember LINUX > POSIX And not just new syscalls … new flags ... 2 examples of richer Linux vs. simpler POSIX fallocate has 7 flags – Insert range – Unshare range – Zero range – Keep size – But POSIX fallocate has no flags Rename (renameat2) has 3 flags – noreplace, whiteout and exchange – POSIX rename has none Network File systems matter ● these extensions to most popular network fs protocol (SMB3) are important ● block devices struggle to do file system tasks: locking, security, leases, consistent metadata Linux Apps need to work over network mounts and continue to work as Linux evolves Improve common situations where customers have Linux and Windows and Mac clients Make sure extensions work with most secure, most optimal SMB3.1.1 dialect (don’t encourage less secure network file systems, or even SMB1/CIFS) Quick Overview of Status ● Linux kernel client: – 5.1 kernel or later can be used.

    Table Of Contents 1. Zoo Information a. Logging in b. Transferring files 2. Unix Basics 3. Homework Commands G etting onto the Zoo Type “ssh <netid>@node.zoo.cs.yale.edu”, and enter your netID password when ​ ​ prompted. Your password won’t show up and the cursor won’t move, but it knows what you’re typing. G etting Files onto the Zoo Use the “scp” command to transfer files onto the Zoo. Type “scp filename1 filename2 ​ ​ ​ <netid>@node.zoo.cs.yale.edu:~/mydirectory/mysubdirectory” ​ You should be on your local machine in the same directory as the two files. This will copy the two local files, filename1 and filename2 into the directory mysubdirectory (which is ​ ​ ​ ​ ​ ​ located inside mydirectory in your home directory on the Zoo). You will be prompted to ​ ​ enter your netID password, just like when you ssh in. U nix Basics What is a directory? A directory is simply a folder, which can contain any mixture of files and ​ subdirectories. What is different about a file versus a directory? A directory contains other files and directories, ​ but does not contain information itself -- for example, you can’t use emacs to view a directory. However, you can often use a text editor to view the contents of a file. Sometimes directories and files have different colors when you look at what’s in your current directory, depending on your terminal settings, which can help you tell which is which. What about an executable? An executable is a special type of file that can be run by your ​ computer.

  • Management of Replicated Volume Location Data in the Ficus
    Appeared in the Proceedings of the Summer USENIX Conference, June 1991, pages 17-29 Management of Replicated Volume Lo cation Data in the Ficus Replicated File System y Thomas W. Page Jr., Richard G. Guy, John S. Heidemann, Gerald J. Popek, Wai Mak, and Dieter Rothmeier Department of Computer Science University of California Los Angeles fpage,guy,popek,johnh,waimak,[email protected] Abstract Existing techniques to provide name transparency in distributed le systems have b een de- signed for mo dest scale systems, and do not readily extend to very large con gurations. This pap er details the approach whichisnow op erational in the Ficus replicated Unix ling envi- ronment, and shows how it di ers from other metho ds currently in use. The Ficus mechanism p ermits optimistic management of the volume lo cation data by exploiting the existing directory reconciliation algorithms which merge directory up dates made during network partition. 1 Intro duction Most Unix le system implementations separate the maintenance of name binding data into two levels: within a volume or lesystem, directory entries bind names to low-level identi ers such as ino des; a second mechanism is used to form a sup er-tree by \gluing" the set of volumes to each other. The traditional Unix volume sup er-tree connection mechanism has b een widely altered or replaced to supp ort b oth small and large scale distributed le systems. Examples of the former are Sun's Network File System NFS [13] and IBM's TCF [12]; larger scale le systems are exempli ed by AFS [7], Decorum [6], Co da [14], Sprite [9], and Ficus [2, 10].
