NAME¶

sxfs - filesystem client based on Skylable SX

SYNOPSIS¶

sxfs [OPTIONS] sx://[profile@]cluster/volume mountpoint

DESCRIPTION¶

sxfs can mount SX volumes as local filesystems. It is based on FUSE and allows for interacting with remote files just as if they were local files on the computer.

OPTIONS¶

-h, --help

Print help and exit

--full-help

Print help, including hidden options, and exit

-V, --version

Print version and exit

-t, --tempdir=PATH

Set directory for temporary files created by sxfs. By default sxfs will create a temporary directory /var/tmp/sxfs-*.

-R, --recovery-dir=PATH

On exit, sxfs will move to the recovery directory all files, which could not be uploaded to the remote volume. By default, it will create a recovery directory /var/tmp/sxfs-*-lost.

-l, --logfile=PATH

Enable logging to the specified file.

-o, --mount-options=OPT

Mount options; see below for the list of available options.

-q, --use-queues

This option enables the use of queues for upload and delete operations. By default sxfs will wait for each operation and report the result to the application performing the action (eg. cp). When this option is enabled, all operations will be queued and performed in the background. This improves the interaction with the mounted volume, however errors might not be reported back to the application. It is highly recommended to use this option together with --logfile and monitor the logfile for possible issues.

-f, --foreground

Run in the foreground.

-D, --debug

Enable debug messages.

-v, --verbose

Log more information about read/write operations. This option automatically enables --debug.

--sx-debug

Enable debug messages from the SX library.

--open-limit=INT

Set the limit for the number of open files (default: 1024).

--fuse-help

Show FUSE help.

--fuse-version

Show FUSE version.

-s, --fuse-single-threaded

Disable multi-threaded operation of FUSE (used for debugging purposes).

--fuse-debug

Run FUSE in debug mode.

-c, --config-dir=PATH

Path to the SX configuration directory (default: ~/.sx)

-f, --filter-dir=PATH

Path to the SX filter directory (default: /usr/lib/sxclient)
