.SH NAME
sxfs \- filesystem client based on Skylable SX
.SH SYNOPSIS
.B sxfs
[\fI\,OPTIONS\/\fR] \fI\,sx://\/\fR[\fI\,profile@\/\fR]\fI\,cluster/volume mountpoint\/\fR
.SH 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.
.SH OPTIONS
.TP
\fB\-h\fR, \fB\-\-help\fR
Print help and exit
.TP
\fB\-\-full\-help\fR
Print help, including hidden options, and exit
.TP
\fB\-V\fR, \fB\-\-version\fR
Print version and exit
.TP
\fB\-t\fR, \fB\-\-tempdir\fR=\fI\,PATH\/\fR
Set directory for temporary files created by sxfs. By default sxfs will create a temporary directory /var/tmp/sxfs-*.
.TP
\fB\-R\fR, \fB\-\-recovery\-dir\fR=\fI\,PATH\/\fR
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.
.TP
\fB\-l\fR, \fB\-\-logfile\fR=\fI\,PATH\/\fR
Enable logging to the specified file.
.TP
\fB\-o\fR, \fB\-\-mount\-options\fR=\fI\,OPT\/\fR
Mount options; see below for the list of available options.
.TP
\fB\-q\fR, \fB\-\-use\-queues\fR
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 \fB\-\-logfile\fR and monitor the logfile for possible issues.
.TP
\fB\-f\fR, \fB\-\-foreground\fR
Run in the foreground.
.TP
\fB\-D\fR, \fB\-\-debug\fR
Enable debug messages.
.TP
\fB\-v\fR, \fB\-\-verbose\fR
Log more information about read/write operations. This option automatically enables \fB\-\-debug\fR.
.TP
\fB\-\-sx\-debug\fR
Enable debug messages from the SX library.
.TP
\fB\-\-open\-limit\fR=\fI\,INT\/\fR
Set the limit for the number of open files (default: 1024).
.TP
\fB\-\-fuse\-help\fR
Show FUSE help.
.TP
\fB\-\-fuse\-version\fR
Show FUSE version.
.TP
\fB\-s\fR, \fB\-\-fuse\-single\-threaded\fR
Disable multi\-threaded operation of FUSE (used for debugging purposes).
.TP
\fB\-\-fuse\-debug\fR
Run FUSE in debug mode.
.TP
