NAME

       umount.s3ql - Unmount an S3QL file system

SYNOPSIS

          umount.s3ql [options] <mount point>

DESCRIPTION

       S3QL is a file system for online data storage. Before using S3QL, make sure to consult the
       full documentation (rather than just  the  man  pages  which  only  briefly  document  the
       available userspace commands).

       The umount.s3ql command unmounts the S3QL file system mounted in the directory mount point
       and blocks until all data has been uploaded to the storage backend.

       Only the user who mounted the file system with mount.s3ql  is  able  to  unmount  it  with
       umount.s3ql.  If  you  are  root  and  want  to  unmount an S3QL file system mounted by an
       ordinary user, you have to use the fusermount -u or umount  command  instead.   Note  that
       these  commands  do not block until all data has been uploaded, so if you use them instead
       of umount.s3ql then you should manually wait  for  the  mount.s3ql  process  to  terminate
       before shutting down the system.

OPTIONS

       The umount.s3ql command accepts the following options.

          --log <target>
                 Destination for log messages. Specify none for standard output or syslog for the
                 system logging daemon. Anything else will be interpreted as  a  file  name.  Log
                 files will be rotated when they reach 1 MiB, and at most 5 old log files will be
                 kept. Default: None

          --debug-modules <modules>
                 Activate debugging  output  from  specified  modules  (use  commas  to  separate
                 multiple modules). Debug messages will be written to the target specified by the
                 --log option.

          --debug
                 Activate debugging output from all S3QL modules. Debug messages will be  written
                 to the target specified by the --log option.

          --quiet
                 be really quiet

          --version
                 just print program version and exit

          --lazy, -z
                 Lazy  umount. Detaches the file system immediately, even if there are still open
                 files. The data will be uploaded in the background once all open files have been
                 closed.

EXIT CODES

       umount.s3ql may terminate with the following exit codes:

       0      Everything went well.

       1      An unexpected error occured. This may indicate a bug in the program.

       2      Invalid command line argument or configuration file key.
