NAME

       vblade-persistence - description of the vblade persistence

DESCRIPTION

       vblade-persistence uses the files in /etc/vblade.conf.d/ to manage exports. File names
       must end in .conf. The "instance" name is the file name without .conf.

       The file format is a POSIX shell fragment.

       The following variables must be defined: netif, shelf, slot, and filename. See vblade(8)
       for their meaning. Incomplete configuration files are ignored, so are files that are not a
       valid shell syntax.

       Additionally, the following variables may be defined:

       ·   options

       Any options as provided by vblade(7).

       ·   ionice

       Use these to define an I/O scheduling class and level for that export. The value must be
       understood by ionice(1).

EXAMPLE

               shelf=14
               slot=2
               netif=ens3
               filename=/dev/mapper/export
               options='-r -m 11:22:33:44:55:66,22:33:44:55:66:77 -o 8'
               ionice='--class best-effort --classdata 7'

USAGE

   On systems using systemd
       Install vblade-generator in /lib/systemd/system-generators/, and both vblade.service and
       vblade@.service in /lib/systemd/system/. Enable the vblade service, reload systemd.
       Additional units for each export should appear, named vblade@<instance>.service.

   On systems using SysV init
       Individual instances may be controlled by providing their name as a second option, e.g.

               /etc/init.d/vblade status demo

       Two different init scripts are available:

   vblade.init.lsb-daemon
       Uses LSB functions and daemon(1) program to control the instance.

       Pros: daemon(1) is a very fine tool for this, providing also respawning and output
       redirection.

   vblade.init.daemon
       As above, but without using LSB functions.

       Pros: Should be fairly portable, no thrills.

   Template
       The template for these scripts is vblade.init.in, the actual templating is done using
       tpage(1p), see vblade.init.generate.

       Support for using Debian’s start-stop-daemon has been prepared but requires pid file
       supprt in vblade to be usable.

BUGS

       On SysV init systems, the configuration files are always sourced as shell scripts. On
       systemd systems, the configuration file is just a key/value store without shell expansion.

       It’s a wise idea to run sh -n against a configuration file after any modification for
       basic format validation.
