Just as 'e' means activation with an exclusive lock,
add an 's' to mean activation with a shared lock.
This allows the existing but implicit behavior of '-ay'
of clvm LVs to be specified explicitly. For local VGs,
asy simply means ay, just like aey means ay.
For local VGs, ay == aey == asy
For clvm VGs, ay == asy, aey == aey, asy == asy
lvmetad_init() should not be called with open connection to the daemon.
Doing so is considered to be an internall error within lvm2 code.
Such coincidence can't occur within current code. Let's assure us it won't
ever happen.
Some of descritpions were misleading at least. Some were completely
off the reality.
lvmetad_init doesn't re-establish or initialise a connection
lvmetad_active and lvmetad_connect_or_warn can do so.
These wrappers have been replaced by direct calls
to vg_read() and find_lv() in previous commits.
This commit should have no functional impact since
all bits were already unreachable.
Previous patch incorrectly skipped replace of @LOCALEDIR@.
The standard option is --localedir so use --with-localedir
as backward compatible option and set localedir if it's not
yet been set (if the could ever happen).
Use double-eval to translate $datarootdir to $prefix to real dir.
Use CFG_DEFAULT_COMMENTED and CFG_DEFAULT_UNDEFINED to
replicate the existing comments in example.conf.
Fix host_list to be cfg_array.
UNDEFINED is only used if the value depends on other
system/kernel values outside of lvm. The most common
case is when dm-thin or dm-cache have built-in default
settings in the kernel, and lvm will use those built-in
default values unless the corresponding lvm config setting
is set.
COMMENTED is used to comment out the default setting in
lvm.conf. The effect is that if the LVM version is
upgraded, and the new version of LVM has new built-in
default values, the new defaults are used by LVM unless
the previous default value was set (uncommented) in lvm.conf.
Introduce new implmentation of dm_task_get_info() function
with support for reading internal_suspend.
.
This time it is done in a 'versioned' way.
We keep the old fashion dm_task_get_info(Base) to implement
the old behavior of 1.02.95 libdm code.
libdm version 1.02.96 introduced 'macro' wrapper
dm_task_get_info_with_deferred_remove with new implementation
of dm_task_get_info() - we cannot do anything else then to
provide compatible version of this symbol.
Now in version 1.02.97 we add new versioned implementation of
dm_task_get_info(DM_1_02_97) symbol.
This has the effect that i.e. rpm build will finaly resolve proper
dependency on a new symbol - so it will be no longer possible,
to build a new binary and use old library
(rpm -q --provides will show libdevmapper.so.1.02(DM_1_02_97)(64bit))
Also the history is now tracked. If a new function is added (or
reimplemented), it needs to be placed in proper file,
so it could be exported with right versioning symbol.
File .exported_symbols.Base should and any existing older DM
should be treated as read-only after a release.
Also - only libdm has been currently enhanced with versioned .Base
file, as soon as other libs (liblvm, libdevmapper-event) needs changes
they should also get their exported symbol files - meanwhile
make.tmpl handles both cases.
Configure provides proper settings for
use_lvmetad and use_lvmpolld conf setttings.
When the build of polld & lvmetad, these settings
are enabled by default unless explicitelly disabled
with --disable-use-lvmetad/--disable-use-lvmpolld.
This is an alternative/equivalent to commit
ca67cf84df
The problem (wrong label->dev after a new preferred
duplicate device is chosen) was isolated to the lvmetad
case (non-lvmetad worked fine), and this fixes the problem
by setting the new label->dev in the lvmetad-specific
code rather than in the general lvmcache code.
In process_each_{vg,lv,pv} when no vgname args are given,
the first step is to get a list of all vgid/vgname on the
system. This is exactly what lvmetad returns from a
vg_list request. The current code is doing a vg_lookup
on each VG after the vg_list and populating lvmcache with
the info for each VG. These preliminary vg_lookup's are
unnecessary, because they will be done again when the
processing functions call vg_read. This patch eliminates
the initial round of vg_lookup's, which can roughly cut in
half the number of lvmetad requests and save a lot of extra work.
