The filesystem_walk API parses the FS internals of a partition and returns a list of all the files and directories contained within. It list deleted files and directories as well. For each node, it reports its relative path, its inode and its allocation status. This is the end user API for inspecting a disk partition content. The command can handle filenames with special characters. Example

Currently, I load the RData file then ls() and str(). But loading the file takes too long if the file is big. Most of the time, I only interested what the variables are in the the file and the attributes of the variables (like if it is a data.frame, matrix, what are the colnames/rownames, etc.) I'm wondering if there is any facility in R to help me avoid loading the whole file.

v2: - Increased the amount of collected information from the FS content. - Moved filesystem_walk0 as internal command. - Code improvement based on comments. - Adhere to project's coding style. - Better command documentation. - More robust tests. Patch ready for review, code available at: https://github.com/noxdafox/libguestfs/tree/filesystem_walk Matteo Cafasso (5): generator:

Looks like it is an issue with architecture compatibility in RPC layer (ie, with XDRs and how it is used). Just glance the logs of the client process where you saw the errors, which could give some hints. If you don't understand the logs, share them, so we will try to look into it. -Amar On Wed, Sep 20, 2017 at 2:40 AM, Walter Deignan <WDeignan at uline.com> wrote: >...

I recently compiled the 3.10-5 client from source on a few PPC64 systems running RHEL 7.3. They are mounting a Gluster volume which is hosted on more traditional x86 servers. Everything seems to be working properly except for creating new directories from the PPC64 clients. The mkdir command gives a "Input/output error" and for the first few minutes the new directory is
