check_lvmlockd_sanlock works with process-each-pv without
the vgreduce parts.
|
| | |
|
| |
|
|
|
|
| |
A very special case where we need to disable
the gl after lockd_gl(ex) to prevent process_each_vg
from changing it with lockd_gl(sh).

sanlock uses 10 sec io timeout by default, but there can be
times when you want to lower that to speed up sanlock operations,
including in the test suite.

This is now used to check if dlm is running, so it's
not an error.

This doesn't work when multiple vgs are removed with
a single vgremove command.

A number of places were wrong, although most didn't matter
because they wouldn't be reached.

This patch adds support for time values used in reporting fields.
The raw values are always stored as number of seconds since epoch.
The support that comes with this patch is the basic one which allows
only for recognition of strictly formatted date and time in selection
criteria (the format follows a subset of formats defined by ISO 8601):
date time timezone
date:
YYYY-MM-DD (or shortly YYYYMMDD)
YYYY-MM (shortly YYYYMM), auto DD=1
YYYY, auto MM=01 and DD=01
time:
hh:mm:ss (or shortly hhmmss)
hh:mm (or shortly hhmm), auto ss=0
hh (or shortly hh), auto mm=0, auto ss=0
timezone (always with + or - sign):
+hh:mm or -hh:mm (or shortly +hhmm or -hhmm)
+hh or -hh
Or directly the time (number of seconds) since Epoch (1970-01-01 00:00:00 UTC)
when the number value is prefixed by "@":
@number_of_seconds_since_epoch
This patch also adds aliases for comparison operators
used together with time values which are more intuitive
to use:
since (as alias for >=)
after (as alias for >)
until (as alias for <=)
before (as alias for <)
For example:
$ lvmconfig --type full report/time_format
time_format="%Y-%m-%d %T %z %Z [%s]"
$ lvs -o name,time vg
LV Time
lvol0 2015-06-28 21:25:41 +0200 CEST [1435519541]
lvol1 2015-06-30 03:25:43 +0200 CEST [1435627543]
lvol2 2015-04-26 14:52:20 +0200 CEST [1430052740]
lvol3 2015-06-30 14:52:23 +0200 CEST [1435668743]
$ lvs vg -o name,time -S 'time since "2015-04-26 15:00" && time until "2015-06-30"'
LV Time
lvol0 2015-06-28 21:25:41 +0200 CEST [1435519541]
lvol1 2015-06-30 03:25:43 +0200 CEST [1435627543]
lvol3 2015-06-30 14:52:23 +0200 CEST [1435668743]
$ lvs vg -o name,time -S 'time since "2015-04-26 15:00" && time until "2015-06-30 6:00"'
LV Time
lvol0 2015-06-28 21:25:41 +0200 CEST [1435519541]
lvol1 2015-06-30 03:25:43 +0200 CEST [1435627543]
$ lvs vg -o name,time -S 'time since @1435519541'
LV Time
lvol0 2015-06-28 21:25:41 +0200 CEST [1435519541]
lvol1 2015-06-30 03:25:43 +0200 CEST [1435627543]
lvol3 2015-06-30 14:52:23 +0200 CEST [1435668743]
This is basic time recognition support that is directly a part of
libdevmapper. Recognition of more free-form expressions will be a
part of subsequent patches.

config_settings.h
Just like we have DEFAULT_USE_LVMETAD (or DEFUALT_USE_LVMPOLLD), use
fallback_to_lvm1=1 lvm.conf setting if we configured lvm2 with
--enable-lvm1-fallback and use fallback_to_lvm1=0 otherwise.
Also, generate proper lvm.conf.in with unconfigured value.

handling reserved values
Just a cleanup - wrap several variables we use to handle reserved
values into a structure for easier manipulation in the code.

This patch allows for registration and recognition of reserved
values which are ranges, so they're composed of two values actually
to denote the lower and upper bound for the range (stored as an array
with exactly two items to define the boundaries).
Also, this patch allows for flagging reserved values as named-only
which means that such values are not strictly reserved. The strictly
reserved values are reserved values as used before this patch.
Distinction between strictly-reserved and named-only values
is clearly visible with comparisons. Normally, strictly reserved
value is not accounted for if we do "greater than" or "lower than"
comparisons, for example:
1 2 3 ....
|
abc
- we have "abc" as reserved value for field with value "2"
- the value reported for the field is "abc" (or "2", it doesn't matter here)
- the selection we're processing is -S 'field < abc'
- the result of the selection gives nothing as "abc" is strictly
reserved value (bound to "2") and there's no order defined for
it and it would only match if we directly compared the value
(so -S 'field = abc' would match)
With named-only values, the "abc" is named-only value for "2",
so selection -S 'field < abc" is the same as using -S 'field < 2'.
The "abc" is just an alias for some value so the value or its
assigned name can be used equally in selection criteria.

Make it possible to define format for time that is displayed.
The way the format is defined is equal to the way that is used
for strftime function, although not all formatting options as
used in strftime are available for LVM2 - the set is restricted
(e.g. we do not allow newline to be printed). The lvm.conf
comments contain the whole list that LVM2 accepts for time format
together with brief description (copied from strftime man page).
For example:
(defaults used - the format is the same as used before this patch)
$ lvs -o+time vg/lvol0 vg/lvol1
LV VG Attr LSize Time
lvol0 vg -wi-a----- 4.00m 2015-06-25 16:18:34 +0200
lvol1 vg -wi-a----- 4.00m 2015-06-29 09:17:11 +0200
(using 'time_format = "@%s"' in lvm.conf - number of seconds
since the Epoch)
$ lvs -o+time vg/lvol0 vg/lvol1
LV VG Attr LSize Time
lvol0 vg -wi-a----- 4.00m @1435241914
lvol1 vg -wi-a----- 4.00m @1435562231

Commit e587b0677b705786a78f21bac1966621f70b2752 broke the build on
systems where /bin/sh is Dash, for example.
Origin patch by Ferenc Wágner <wferi@niif.hu> changed later to
avoid using shell call, so makefile add 'server' target when
one of metad or polld daemon is requested.

Do not display settings with undefined default values, but do display
these settings in case the value is defined directly in any part of
the existing config cascade.
For example, the lvmconfig --type current always displays these settings
(as it's somewhere in "current" configuration cascade that makes it defined).
The lvmconfig --type full displays these settings only if it's defined
somewhere in the cascade, but not if default value is used instead
The lvmconfig --type default never displays these settings...
More concrete example - let's have activation/volume_list directly
set in lvm.conf and activation/read_only_volume_list not set.
Both of these settings have *undefined default* values.
$lvmconfig --type full activation/volume_list activation/read_only_volume_list
volume_list="/dev/vg/lv"
(...only volume_list is defined, hence it's printed)
However, the comments will display more info (see also previous commit):
$lvmconfig --type full activation/volume_list activation/read_only_volume_list --withsummary
# Configuration option activation/volume_list.
# Only LVs selected by this list are activated.
# This configuration option does not have a default value defined.
# Value defined in existing configuration has been used for this setting.
volume_list="/dev/vg/lv"
# Configuration option activation/read_only_volume_list.
# LVs in this list are activated in read-only mode.
# This configuration option does not have a default value defined.
