The OpenAIS checkpoint library is going away; therefore, cmirrord must
operate without it. The algorithms the handle the timing of when to send
a checkpoint, the determination of what to send, and which ongoing cluster
requests are relevent with respect to the checkpoints are unaffected. We
need only replace the functions that actually perform the storing/transmitting
and retrieving/receiving of the checkpoint data. Rather than store the
checkpoint data in an OpenAIS checkpoint file, we simply transmit it along
with the message that notifies the incoming node that the checkpoint is
ready.
/etc/tmpfiles.d directory holds configuration files for temporary/volatile
files and directories that should be automatically managed. For example,
if we have some parts of the fs hierarchy on tmpfs, we'd like to recreate
some files or directories on every boot so they're always prepared for use.
Systemd can read such configuration files. For now, the lock and run directory
are the ones that are most probably placed on tmpfs. If this is the case, we
can install the configuration by 'make install_tmpfiles_configuration'.
Built-in blkid is supported since udev v176 - set the UDEV_HAS_BUILTIN_BLKID
variable appropriately so we can use it in the rules to call the built-in
blkid conditionaly.
udev may also need to be disabled if you didn't build it statically too.
dmeventd.static could be fixed with some more work but I don't really see the
point: without dlopen() it's useless, and if you have dlopen(), why not support
normal shared libraries too?
Next iteration for better fit of lvmetad compilation.
Move build of libdaemon.a into common subdir Makefile.
libdaemon.a is device-mapper target.
Build and install lvmetad as lvm2 target.
Read 2 environmental vars to learn about overide position for
CLVMD and LVM binaries.
We support LVM_BINARY in other script - and this way we could easily
test restart in our test-suite.
Implementation described in doc/lvm2-raid.txt.
Basic support includes:
- ability to create RAID 1/4/5/6 arrays
- ability to delete RAID arrays
- ability to display RAID arrays
Notable missing features (not included in this patch):
- ability to clean-up/repair failures
- ability to convert RAID segment types
- ability to monitor RAID segment types
Make configurable default behaviour how to deal with device node creates.
With udev system natural options should be 'resume'.
For older systems where user expect there is node in /dev/mapper immediately
after dmsetup create --notable - use 'create'
FIXME:
Code needs fixing passing this flag through udev cookie.
Switch dmeventd to use dm_create_lockfile and drop duplicate code.
Allow clvmd pidfile to be configurable.
Switch cmirrord and clvmd to use dm_create_lockfile.
Indent updates.
Use AC_HELP_STRING for help string.
Start help string with lower letter.
Add [] around some default values i.e. [TYPE=internal].
Skip some "" around shell assigment when not needed.
Fix typo --with-device-gid=UID string.
Introduce lvm_exec_prefix with resolved exec_prefix.
(using same ac_default_prefix as for CLVMD_PATH)
Use lvm_exec_prefix instead of dmeventd_prefix (fixes missing ac_default_prefix)
Note: This patch is rather hot-fix as currently generate code
does not create correct code for make exec_prefix=
Adding configure.in support for Replicators.
Adding basic lib lvm support for Replicators.
Adding flags REPLICATOR and REPLICATOR_LOG.
Adding segments SEG_REPLICATOR and SEG_REPLICATOR_DEV.
Adding basic methods for handling replicator metadata.
Patch is inspired by Debian's extra patch.
- removes OWNER & GROUP make vars they are parts of INSTALL command.
- adds INSTALL_PROGRAM for executable, uses $(INSTALL)
- adds INSTALL_DATA for non-executable data, uses ($INSTALL)
- adds INSTALL_WDATA for writable non-executable data, uses ($INSTALL)
- adds configure option --enable-write_install - to support
installatin of writable files used by distribution
- replaces usage of ifeq @LIB_SUFFIX@ with $(LIB_SUFFIX)
- installs .a files from static builds without executable flag
- installs .a files to $(usrlibdir) instead of $(libdir)
- installs all static binaries to $(staticdir)
- create .so links for devel package in $(usrlibdir) instead of
$(libdir)
- makes .so and .so.LIB_VERSION files within builddir
- removes VERSIONED_SHLIB and created versioned LIB_SHARED automagicaly
- install LIB_SHARED via install_lib_shared target
- install plugins via install_lib_shared_plugin target
- prints whole 'install' command during installation instead of less
informative "Installing $(something) $(somewhere)"
- install multiple man pages with one INSTALL command
- use DISTCLEAN_TARGETS instead of creating multiple distclean targets
to check for presence of this module and avoid using --frames
option for genhtml in this case.
Fix arg list for AC_PATH_PROG for lcov and genhtml.
(detecting empty LCOV and GENHTML string in Makefiles).
For static builds dependency for SELinux libs is not handled by 'ar'.
Till better solution is found, for static builds STATIC_LIBS is used.
Patch updates SELinux detection to use 3rd & 4th parameter for Success/Fail.
Also removes detection of pthread from this check as we know which
version of libdevmapper we are going to link with lvm after merge.
SELinux header check moved to the SELinux test code.
Create new substituted variable PTHREAD_LIBS and link this library
only with tools/libs which really needs it - i.e. dmeventd.
Check for libpthread only for builds with clvmd or dmeventd.
Remove variable LIB_PTHREAD
Modify linking of readline library. Create new substituted varible
READLINE_LIBS - readline library is linked ONLY with tools that really use
it - i.e. lvm. (Static lvm does not use readlin).
Previous behaviour put this library into the variable LIBS and thus
linked it with all created object files of lvm project (i.e. plugins...).
READLINE detection is simplified.
Termcap library is linked in only if readline library doesn't have its own
dependency (i.e. old distributions).
Per discussion on lvm-devel mailing list and part of debian patch set,
don't set defaults for owner and group, since nobody seems to use them, and
still allow override.
Add configure --enable-units-compat to set si_unit_consistency off by default.
Use standard output units for 'PE Size' and 'Stripe size' in pv/lvdisplay.
The original liblvm.a has been moved to liblvm-internal.a.
We now use liblvm.a for the new application library and build
it inside liblvm directory.
Change dependencies so tools depend on liblvm application library,
and application library depends on liblvm internal.
failed to link against liblvm2cmd.
Dmeventd DSOs *require* lvm2cmd to be linked in.
For the future:
1) AC_SUBST does not create Makefile variables, only @foo@-style substitutions
2) When using `test', whitespace around `=' is essential:
test a=b is true, as is test a=a

Add --config for overriding most config file settings from cmdline.
Quote arguments when printing command line.
Remove linefeed from 'initialising logging' message.
Add 'Completed' debug message.
Don't attempt library exit after reloading config files.
Always compile with libdevmapper, even if device-mapper is disabled.
Fix some memory leaks in error paths found by coverity.
Use C99 struct initialisers.
Move DEFS into configure.h.
Clean-ups to remove miscellaneous compiler warnings.
./configure --with-clvmd
wil do this by default. Or you can choose which you want with
./configure --with-clvmd=gulm or
./configure --with-clvmd=cman
When clvmd with both included is run, it will automatically detect the cluster
manager in use.
Clear many compiler warnings (i386) & associated bugs - hopefully without
introducing too many new bugs:-) (Same exercise required for other archs.)
Default compilation has optimisation - or else use ./configure --enable-debug
Current version of LVM2 instead relies on /usr/include/libdevmapper.h
which gets installed by the device mapper package.
(Should this location now be configurable?)
devices {
# first match is final, eg. /dev/ide/cdrom

Alasdair this is ready to roll into the tools now.
and builds a *very* efficient engine that will tell you which regex a string
matches with only a single pass through the string. To be used in the config
file when specifying devices.
o Anchor's aren't supported yet (^ and $) but that won't take long.
o Also when we get some realistic config files we may want to consider adding an
extra level of indirection to the dfa state in order to compress the table.
It all depends on how large typical tables get.
