LVM poll daemon overview
|
||||
========================
|
||||
|
||||
(last updated: 2015-05-09)
|
||||
|
||||
LVM poll daemon (lvmpolld) is the alternative for lvm2 classical polling
|
||||
mechanisms. The motivation behind new lvmpolld was to create persistent
|
||||
system service that would be more durable and transparent. It's suited
|
||||
particularly for any systemd enabled distribution.
|
||||
|
||||
Before lvmpolld any background polling process originating in a lvm2 command
|
||||
initiated inside cgroup of a systemd service could get killed if the main
|
||||
process (service) exited in such cgroup. That could lead to premature termination
|
||||
of such lvm2 polling process.
|
||||
|
||||
Also without lvmpolld there were no means to detect a particular polling process
|
||||
suited for monitoring of specific operation is already in-progress and therefore
|
||||
it's not desirable to start next one with exactly same task. lvmpolld is able to
|
||||
detect such duplicate requests and not spawn such redundant process.
|
||||
|
||||
lvmpolld is primarily targeted for systems with systemd as init process. For systems
|
||||
without systemd there's no need to install lvmpolld because there is no issue
|
||||
with observation described in second paragraph. You can still benefit from
|
||||
avoiding duplicate polling process being spawned, but without systemd lvmpolld
|
||||
can't easily be run on-demand (activated by a socket maintained by systemd).
|
||||
|
||||
lvmpolld implement shutdown on idle and can shutdown automatically when idle
|
||||
for requested time. 60 second is recommended default here. This behaviour can be
|
||||
turned off if found useless.
|
||||
|
||||
Data structures
|
||||
---------------
|
||||
|
||||
a) Logical Volume (struct lvmpolld_lv)
|
||||
|
||||
Each operation is identified by LV. Internal identifier within lvmpolld
|
||||
is full LV uuid (vg_uuid+lv_uuid) prefixed with LVM_SYSTEM_DIR if set by client.
|
||||
|
||||
such full identifier may look like:
|
||||
|
||||
"/etc/lvm/lvm.confWFd2dU67S8Av29IcJCnYzqQirdfElnxzhCdzEh7EJrfCn9R1TIQjIj58weUZDre4"
|
||||
|
||||
or without LVM_SYSTEM_DIR being set explicitly:
|
||||
|
||||
"WFd2dU67S8Av29IcJCnYzqQirdfElnxzhCdzEh7EJrfCn9R1TIQjIj58weUZDre4"
|
||||
|
||||
|
||||
LV carries various metadata about polling operation. The most significant are:
|
||||
|
||||
VG name
|
||||
LV name
|
||||
polling interval (usually --interval passed to lvm2 command or default from lvm2
|
||||
configuration)
|
||||
operation type (one of: pvmove, convert, merge, thin_merge)
|
||||
LVM_SYSTEM_DIR (if set, this is also passed among environment variables of lvpoll
|
||||
command spawned by lvmpolld)
|
||||
|
||||
b) LV stores (struct lvmpolld_store)
|
||||
|
||||
lvmpolld uses two stores for Logical volumes (struct lvmpolld_lv). One store for polling
|
||||
operations in-progress. These operations are as of now: PV move, mirror up-conversion,
|
||||
classical snapshot merge, thin snapshot merge.
|
||||
|
||||
The second store is suited only for pvmove --abort operations in-progress. Both
|
||||
stores are independent and identical LVs (pvmove /dev/sda3 and pvmove --abort /dev/sda3)
|
||||
can be run concurently from lvmpolld point of view (on lvm2 side the consistency is
|
||||
guaranteed by lvm2 locking mechanism).
|
||||
|
||||
Locking order
|
||||
-------------
|
||||
|
||||
There are two types of locks in lvmpolld. Each store has own store lock and each LV has
|
||||
own lv lock.
|
||||
|
||||
Locking order is:
|
||||
1) store lock
|
||||
2) LV lock
|
||||
|
||||
Each LV has to be inside a store. When daemon requires to take both locks it has
|
||||
to take a store lock first and LV lock has to be taken afterwards (after the
|
||||
appropriate store lock where the LV is being stored :))

.SH DESCRIPTION
|
||||
lvmpolld is polling daemon for LVM. The daemon receives requests for polling
|
||||
of already initialised operations originating in LVM2 command line tool.
|
||||
The requests for polling originates in \fBlvconvert\fP, \fBpvmove\fP,
|
||||
\fBlvchange\fP or \fBvgchange\fP LVM2 command.
|
||||
|
||||
The purpose of lvmpolld is to reduce the number of spawned background processes
|
||||
per otherwise unique polling operation. There should be only one. It also eliminates
|
||||
the possibility of unsolicited termination of background process by external factors.
|
||||
|
||||
lvmpolld is used by LVM only if it is enabled in \fBlvm.conf\fP(5) by specifying the
|
||||
\fBglobal/use_lvmpolld\fP setting. If this is not defined in the LVM configuration
|
||||
explicitly then default setting is used instead (see the output of
|
||||
\fBlvmconfig \-\-type default global/use_lvmpolld\fP command).
|
||||
.SH OPTIONS
|
||||
|
||||
To run the daemon in a test environment both the pidfile_path and the
|
||||
socket_path should be changed from the defaults.
|
||||
.TP
|
||||
.B \-f
|
||||
Don't fork, but run in the foreground.
|
||||
.TP
|
||||
.BR \-h ", " \-?
|
||||
Show help information.
|
||||
.TP
|
||||
.IR \fB\-l " {" all | wire | debug }
|
||||
Select the type of log messages to generate.
|
||||
Messages are logged by syslog.
|
||||
Additionally, when \-f is given they are also sent to standard error.
|
||||
There are two classes of messages: wire and debug. Selecting 'all' supplies both
|
||||
and is equivalent to a comma-separated list \-l wire,debug.
|
||||
.TP
|
||||
.B \-p \fIpidfile_path
|
||||
Path to the pidfile. This overrides both the built-in default
|
||||
(#DEFAULT_PID_DIR#/lvmpolld.pid) and the environment variable
|
||||
\fBLVM_LVMPOLLD_PIDFILE\fP. This file is used to prevent more
|
||||
than one instance of the daemon running simultaneously.
|
||||
.TP
|
||||
.B \-s \fIsocket_path
|
||||
Path to the socket file. This overrides both the built-in default
|
||||
(#DEFAULT_RUN_DIR#/lvmpolld.socket) and the environment variable
|
||||
\fBLVM_LVMPOLLD_SOCKET\fP.
|
||||
.TP
|
||||
.B \-t \fItimeout_value
|
||||
When runs as native systemd service daemon may shutdown after being
|
||||
idle for the given time (in seconds). When the option is omitted or
|
||||
the value given is zero the daemon never shutdowns on idle. When
|
||||
the daemon doesn't run as native systemd service the timeout is
|
||||
ignored and never shutdowns on idle.
|
||||
.TP
|
||||
.B \-B \fIlvm_binary_path
|
||||
Optional path to alternative LVM binary (default: #LVM_PATH#). Use for
|
||||
testing purposes only.
|
||||
.TP
|
||||
.B \-V
|
||||
Display the version of lvmpolld daemon.
|
||||
.SH ENVIRONMENT VARIABLES
|
||||
.TP
|

.B LVM_LVMPOLLD_PIDFILE
|
||||

|

.TP
|
||||
.B LVM_LVMPOLLD_SOCKET
|
||||
Path for the socket file.
