If ++.B mpathconf ++is called with no commands, it will display the current configuration. ++ ++The default options for mpathconf are ++.B --with_module ++The ++.B --with_multipathd ++option is not set by default. Enabling multipathing will load the ++.B dm_multipath ++module but it will not immediately start it. This is so ++that users can manually edit their config file if necessary, before starting ++.B multipathd. ++ ++If ++.B /etc/multipath.conf ++already exists, mpathconf will edit it. If it does not exist, mpathconf will ++use ++.B /usr/share/doc/device-mapper-multipath-0.4.9/multipath.conf ++as the starting file. This file has ++.B user_friendly_names ++set. If this file does not exist, mpathconf will create ++.B /etc/multipath.conf ++from scratch. For most users, this means that ++.B user_friendly_names ++will be set by default, unless they use the ++.B --user_friendly_names n ++command. ++.SH COMMANDS ++.TP ++.B --enable ++Removes any line that blacklists all device nodes from the ++.B /etc/multipath.conf ++blacklist section. ++.TP ++.B --disable ++Adds a line that blacklists all device nodes to the ++.B /etc/multipath.conf ++blacklist section. If no blacklist section exists, it will create one. ++.TP ++.B --user_friendly_name \fP { \fBy\fP | \fBn\fP } ++If set to \fBy\fP, this adds the line ++.B user_friendly_names yes ++to the ++.B /etc/multipath.conf ++defaults section. If set to \fBn\fP, this removes the line, if present. This ++command can be used along with any other command. ++.TP ++.B --find_multipaths\fP { \fBy\fP | \fBn\fP } ++If set to \fBy\fP, this adds the line ++.B find_multipaths yes ++to the ++.B /etc/multipath.conf ++defaults section. If set to \fBn\fP, this removes the line, if present. This ++command can be used aldong with any other command. ++.SH OPTIONS ++.TP ++.B --with_module\fP { \fBy\fP | \fBn\fP } ++If set to \fBy\fP, this runs ++.B modprobe dm_multipath ++to install the multipath modules. This option only works with the ++.B --enable ++command. This option is set to \fBy\fP by default. ++.TP ++.B --with_multipathd { \fBy\fP | \fBn\fP } ++If set to \fBy\fP, this runs ++.B service multipathd start ++to start the multipathd daemon on \fB--enable\fP, ++.B service multipathd stop ++to start the multipathd daemon on \fB--disable\fP, and ++.B service multipathd reload ++to reconfigure multipathd on \fB--user_frindly_names\fP and ++\fB--find_multipaths\fP. ++This option is set to \fBn\fP by default. ++.SH FILES ++.BR /etc/multipath.conf ++.SH "SEE ALSO" ++.BR multipath.conf (5), ++.BR modprobe (8), ++.BR multipath (8), ++.BR multipathd (8), ++.BR service (8), ++.SH AUTHOR ++Benjamin Marzinski diff --git a/SOURCES/0006-RH-add-find-multipaths.patch b/SOURCES/0006-RH-add-find-multipaths.patch new file mode 100644 index 0000000..4a0c364 --- /dev/null +++ b/SOURCES/0006-RH-add-find-multipaths.patch @@ -0,0 +1,222 @@ +--- + libmultipath/config.c | 1 + + libmultipath/config.h | 1 + + libmultipath/configure.c | 11 +++++++++++ + libmultipath/defaults.h | 1 + + libmultipath/dict.c | 34 ++++++++++++++++++++++++++++++++++ + libmultipath/wwids.c | 26 ++++++++++++++++++++++++++ + libmultipath/wwids.h | 1 + + multipath/main.c | 2 +- + multipathd/main.c | 6 ++++++ + 9 files changed, 82 insertions(+), 1 deletion(-) + +Index: multipath-tools-130222/libmultipath/config.c +=================================================================== +--- multipath-tools-130222.orig/libmultipath/config.c ++++ multipath-tools-130222/libmultipath/config.c +@@ -547,6 +547,7 @@ load_config (char * file) + conf->reassign_maps = DEFAULT_REASSIGN_MAPS;

The specific use + case for me is when LIO exports rbd images through multiple LIO + instances. + + The problem it handles is when rbd instance1 has the exclusive lock, + but becomes unreachable another host in the cluster will take over + and blacklist the instance1. This prevents it from sending stale IO + and corrupting data. + + Later, when the host is reachable, we will want to failback to it. + To this, the checker will detect we were blacklisted, unmap the old + image which will make sure old IO is failed, and then remap the +image + and unblacklist the host. multipathd will then handle this like a + path being removed and re-added. + +-------- + +Porting notes: +Added rbd to multipath.conf.annotated. + +Signed-off-by: Mike Christie +--- + libmultipath/checkers/Makefile | 7 + libmultipath/checkers/rbd.c | 639 +++++++++++++++++++++++++++++++++++++++++ + multipath.conf.annotated | 4 + multipath/multipath.conf.5 | 3 + 4 files changed, 651 insertions(+), 2 deletions(-) + create mode 100644 libmultipath/checkers/rbd.c + +Index: multipath-tools-130222/libmultipath/checkers/Makefile +=================================================================== +--- multipath-tools-130222.orig/libmultipath/checkers/Makefile ++++ multipath-tools-130222/libmultipath/checkers/Makefile +@@ -14,10 +14,17 @@ LIBS= \ + libcheckhp_sw.so \ + libcheckrdac.so + ++ifeq ($(shell test -r /usr/include/rados/librados.h && echo 1),1) ++LIBS += libcheckrbd.so ++endif ++ + CFLAGS += -fPIC -I.. + + all: $(LIBS) + ++libcheckrbd.so: rbd.o ++ $(CC) $(LDFLAGS) $(SHARED_FLAGS) -o $@ $^ -lrados -ludev ++ + libcheckdirectio.so: libsg.o directio.o + $(CC) $(LDFLAGS) $(SHARED_FLAGS) -o $@ $^ -laio + +Index: multipath-tools-130222/libmultipath/checkers/rbd.c +=================================================================== +--- /dev/null ++++ multipath-tools-130222/libmultipath/checkers/rbd.c +@@ -0,0 +1,639 @@ ++/* ++ * Copyright (c) 2016 Red Hat ++ * Copyright (c) 2004 Christophe Varoqui ++ * ++ * Code based off of tur.c and ceph's krbd.cc ++ */ ++#define _GNU_SOURCE ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++ ++#include "rados/librados.h" ++ ++#include "structs.h" ++#include "checkers.h" ++ ++#include "../libmultipath/debug.h" ++#include "../libmultipath/uevent.h" ++ ++struct rbd_checker_context; ++typedef int (thread_fn)(struct rbd_checker_context *ct, char *msg); ++ ++#define RBD_MSG(msg, fmt, args...) snprintf(msg, CHECKER_MSG_LEN, fmt, ##args); ++ ++struct rbd_checker_context { ++ int rbd_bus_id; ++ char *client_addr; ++ char *config_info; ++ char *snap; ++ char *pool; ++ char *image; ++ char *username; ++ int remapped; ++ int blacklisted; ++ ++ rados_t cluster; ++ ++ int state; ++ int running; ++ time_t time; ++ thread_fn *fn; ++ pthread_t thread; ++ pthread_mutex_t lock; ++ pthread_cond_t active; ++ pthread_spinlock_t hldr_lock; ++ int holders; ++ char message[CHECKER_MSG_LEN]; ++}; ++ ++int libcheck_init(struct checker * c) ++{ ++ struct rbd_checker_context *ct; ++ struct udev_device *block_dev; ++ struct udev_device *bus_dev; ++ struct udev *udev; ++ struct stat sb; ++ const char *block_name, *addr, *config_info; ++ const char *image, *pool, *snap, *username; ++ char sysfs_path[PATH_SIZE]; ++ int ret; ++ ++ ct = malloc(sizeof(struct rbd_checker_context)); ++ if (!ct) ++ return 1; ++ memset(ct, 0, sizeof(struct rbd_checker_context)); ++ ct->holders = 1; ++ pthread_cond_init(&ct->active, NULL); ++ pthread_mutex_init(&ct->lock, NULL); ++ pthread_spin_init(&ct->hldr_lock, PTHREAD_PROCESS_PRIVATE); ++ c->context = ct; ++ ++ /* ++ * The rbd block layer sysfs device is not linked to the rbd bus ++ * device that we interact with, so figure that out now. ++ */ ++ if (fstat(c->fd, &sb) != 0) ++ goto free_ct; ++ ++ udev = udev_new(); ++ if (!udev) ++ goto free_ct; ++ ++ block_dev = udev_device_new_from_devnum(udev, 'b', sb.st_rdev); ++ if (!block_dev) ++ goto free_udev; ++ ++ block_name = udev_device_get_sysname(block_dev); ++ ret = sscanf(block_name, "rbd%d", &ct->rbd_bus_id); ++ ++ udev_device_unref(block_dev); ++ if (ret != 1) ++ goto free_udev; ++ ++ snprintf(sysfs_path, sizeof(sysfs_path), "/sys/bus/rbd/devices/%d", ++ ct->rbd_bus_id); ++ bus_dev = udev_device_new_from_syspath(udev, sysfs_path); ++ if (!bus_dev) ++ goto free_udev; ++ ++ addr = udev_device_get_sysattr_value(bus_dev, "client_addr"); ++ if (!addr) { ++ condlog(0, "Could not find client_addr in rbd sysfs.

Grouping commands in batch files can provide a speed ++improvement in particular on large installments, because \fBmpathpersist\fR ++needs to scan existing paths and maps only once during startup. ++. ++.PP ++The input file is a text file that is parsed ++line by line. Every line of the file is interpreted as a command line ++(i.e. list of options and parameters) for \fBmpathpersist\fR. Options ++and parameters are separated by one or more whitespace characters (space or TAB). ++Lines can, but do not have to, begin with the word \(dqmpathpersist\(dq. ++The \(dq#\(dq character, either at the beginning of the line or following ++some whitespace, denotes the start of a comment that lasts until the end of the ++line. Empty lines are allowed. Continuation of mpathpersist commands over ++multiple lines is not supported. ++. ++.PP ++All options listed in this man page, except \fI-f\fR and ++\fI-v\fR, are allowed in batch files. Both short and long option formats may be used. ++Using the \fI-f\fR option inside the batch file is an error. The \fI-v\fR ++option is ignored in batch files. ++. ++.PP ++The multipath map on which to act must be specified on every input line, e.g. using the \fI-d\fR option. ++Commands acting on different multipath maps may be combined in a ++batch file, and multiple commands may act on the same multipath ++map. Commands are executed one by one, so ++that commands further down in the file see status changes caused by previous ++commands. ++If \fBmpathpersist\fR encounters an error while processing a line in the ++batch file, batch file processing is \fBnot\fR aborted; subsequent commands ++are executed nonetheless. The exit status of \fBmpathpersist\fR is the status ++of the first failed command, or 0 if all commands succeeded. ++. ++.PP ++If other options and parameters are used along with ++\fI-f\fR on the \fBmpathpersist\fR command line, the command line will be executed first, followed ++by the commands from the the batch file. ++. ++.PP ++Below is an example of a valid batch input file. ++. + .PP ++.RS ++.EX ++# This is an mpathpersist input file. ++# Short and long forms of the same command ++-i -k /dev/dm-1 # short form, this comment is ignored ++mpathpersist --in --read-keys --device=/dev/dm-1 ++ ++# Mixing of long and short options, variable white space ++ --out --register -S abcde /dev/dm-1 ++ ++# Mixing of commands for different maps ++-ir /dev/dm-0 ++-ir /dev/dm-1 ++ ++mpathpersist --out --param-rk abcde --reserve --prout-type 5 /dev/dm-1 ++# This should now show a reservation ++-ir /dev/dm-1 ++-oCK abcde /dev/dm-1 ++--in --read-reservation /dev/dm-1 ++.EE ++.RE ++. ++. ++.\" ---------------------------------------------------------------------------- ++.SH "SEE ALSO" ++.\" ---------------------------------------------------------------------------- ++. ++.BR multipath (8), ++.BR multipathd (8), ++.BR sg_persist (8). ++. ++. ++.\" ---------------------------------------------------------------------------- ++.SH AUTHORS ++.\" ---------------------------------------------------------------------------- ++. ++\fImultipath-tools\fR was developed by Christophe Varoqui ++and others. ++.\" EOF diff --git a/SOURCES/0266-RHBZ-1696817-fix-emc-checker.patch b/SOURCES/0266-RHBZ-1696817-fix-emc-checker.patch new file mode 100644 index 0000000..c7bf33a --- /dev/null +++ b/SOURCES/0266-RHBZ-1696817-fix-emc-checker.patch @@ -0,0 +1,219 @@ +--- + libmultipath/checkers.c | 29 +++++++++++++++++++++++++++-- + libmultipath/checkers.h | 2 ++ + libmultipath/checkers/cciss_tur.c | 5 +++++ + libmultipath/checkers/directio.c | 5 +++++ + libmultipath/checkers/emc_clariion.c | 7 +++++++ + libmultipath/checkers/hp_sw.c | 5 +++++ + libmultipath/checkers/rdac.c | 5 +++++ + libmultipath/checkers/readsector0.c | 5 +++++ + libmultipath/checkers/tur.c | 5 +++++ + libmultipath/discovery.c | 2 ++ + 10 files changed, 68 insertions(+), 2 deletions(-) + +Index: multipath-tools-130222/libmultipath/checkers.c +=================================================================== +--- multipath-tools-130222.orig/libmultipath/checkers.c ++++ multipath-tools-130222/libmultipath/checkers.c +@@ -132,6 +132,13 @@ struct checker * add_checker (char * nam + if (!c->init) + goto out;
