Subject: [PATCH] multipath-tools: Introducing multipath C API
|
|
|
|
|
|
|
|
|
|
Features:
|
|
|
|
|
|
|
|
|
|
* Use mpath_cmd.h for IPC connection and use output of 'show maps json'.
|
|
|
|
|
* Library user guide will be 'man 3 libdmmp.h'.
|
|
|
|
|
* Every public function has its own manpage in section 3 which is
|
|
|
|
|
generated by linux 'kernel-doc' tool.
|
|
|
|
|
|
|
|
|
|
Usage:
|
|
|
|
|
|
|
|
|
|
make -j5
|
|
|
|
|
sudo make install \
|
|
|
|
|
bindir=/usr/sbin/ \
|
|
|
|
|
syslibdir=/usr/lib64/ \
|
|
|
|
|
libdir=/usr/lib64/multipath \
|
|
|
|
|
rcdir=/etc/rc.d/init.d \
|
|
|
|
|
unitdir=/usr/lib/systemd/system \
|
|
|
|
|
includedir=/usr/include
|
|
|
|
|
make -C libdmmp check
|
|
|
|
|
make -C libdmmp speed_test
|
|
|
|
|
|
|
|
|
|
man libdmmp.h
|
|
|
|
|
man dmmp_mpath_array_get
|
|
|
|
|
man <dmmp function name>
|
|
|
|
|
|
|
|
|
|
Performance:
|
|
|
|
|
|
|
|
|
|
* 10k scsi_debug sdX with 2 disks per mpath (i7-6820HQ 16GiB RAM):
|
|
|
|
|
$ make -C libdmmp speed_test
|
|
|
|
|
Got 5000 mpath
|
|
|
|
|
real 3.22
|
|
|
|
|
user 0.15
|
|
|
|
|
sys 0.01
|
|
|
|
|
|
|
|
|
|
Misc:
|
|
|
|
|
* Developer note is libdmmp/DEV_NOTES.
|
|
|
|
|
|
|
|
|
|
Changes since V4:
|
|
|
|
|
|
|
|
|
|
* Add new function dmmp_mpath_kdev_name_get() to query the '/dev/dm-01' for
|
|
|
|
|
mpath.
|
|
|
|
|
* Updated manpages.
|
|
|
|
|
* Rebased to current master ea4367159d32444e48a409a4f1c4f18324b737a9.

|
|
|
|
+ * Linux Kernel code style.
|
|
|
|
|

|
|
|
|
|
+ * Don't use enum.
|
|
|
|
|

|
|
|
+#include <libdmmp/libdmmp.h>
|
|
|
|
|
+
|
|
|
|
|
+.SH "DESCRIPTION"
|
|
|
|
|
+
|
|
|
|
|
+All the libdmmp public functions ships its own man pages.
|
|
|
|
|
+Use 'man 3 <function_name>' to check the detail usage.
|
|
|
|
|
+
|
|
|
|
|
+.SH "USAGE"
|
|
|
|
|
+
|
|
|
|
|
+To use libdmmp in your project, we suggest to use the 'pkg-config' way:
|
|
|
|
|
+
|
|
|
|
|
+ * Add this line into your configure.ac:
|
|
|
|
|
+
|
|
|
|
|
+ PKG_CHECK_MODULES([LIBDMMP], [libdmmp])
|
|
|
|
|
+
|
|
|
|
|
+ * Add these lines into your Makefile.am:
|
|
|
|
|
+
|
|
|
|
|
+ foo_LDFLAGS += $(LIBDMMP_LIBS)
|
|
|
|
|
+ foo_CFLAGS += $(LIBDMMP_CFLAGS)
|
|
|
|
|
+
|
|
|
|
|
+.SH LOG HANDLING
|
|
|
|
|
+
|
|
|
|
|
+The log handler function could be set via 'dmmp_context_log_func_set()'.
|
|
|
|
|
+The log priority could be set via 'dmmp_context_log_priority_set()'.
|
|
|
|
|
+
|
|
|
|
|
+By default, the log priorities is 'DMMP_LOG_PRIORITY_WARNING'.
|
|
|
|
|
+By default, the log handler is print log to STDERR, and its code is listed
|
|
|
|
|
+below in case you want to create your own log handler.
