The rationale for removing init_verbose() call is very similar to removing
init_debug() call. create_toolcontext() calls _init_logging() which
makes these calls:
/* Verbose level for tty output */
cmd->default_settings.verbose =
find_config_tree_int(cmd, "log/verbose", DEFAULT_VERBOSE);
init_verbose(cmd->default_settings.verbose + VERBOSE_BASE_LEVEL);
And being that create_toolcontext() copies default_settings into
current_settings at the bottom, the init_verbose() call we are removing:
init_verbose(cmd->current_settings.verbose + VERBOSE_BASE_LEVEL);
is redundant.
We can safely remove because create_toolcontext() calls _init_logging(),
which makes these calls:
/* Debug level for log file output */
cmd->default_settings.debug =
find_config_tree_int(cmd, "log/level", DEFAULT_LOGLEVEL);
init_debug(cmd->default_settings.debug);
Then at the bottom of create_toolcontext() we do this:
cmd->current_settings = cmd->default_settings;
So the call we are removing from init_lvm() functions (clvmd and lvmcmdline):
init_debug(cmd->current_settings.debug);
Just sets the value of debug based on 'cmd->current_settings.debug'.
Since cmd->current_settings is equivalent to cmd->default_settings, and
init_debug() was called with cmd->default_settings, the call we remove is
redundant.
snapshot DSO unregistered itself when snapshot changed state to invalid.
This can cause a race (and several timeouts), when for example another snapshot
is added and in the middle of operation (suspend/resume) the monitoring thread
unregister itself.
Fix it by keeping the snapshot monitored after invalidation - just reset
threshold to not really print any messages to syslog.
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
* configure.in (LVM2CMD_LIB): Define if --enable-cmdlib.
* dmeventd/mirror/Makefile.in (CLDFLAGS): Use $(LVM2CMD_LIB) rather
than hard-coding -llvm2cmd.
* dmeventd/snapshot/Makefile.in (CLDFLAGS): Likewise.
which is not used since the switch away from async version saLck
. num_nodes should equal to member_list_entries, i.e.
joined_list_entires is 0 when a node leaves the group.
Thanks to Xinwei Hu for the patch.
It does 2 things.
1. The cpg_deliver_callback make a compare between target_nodeid and our_nodeid.
It turns out openais set target_nodeid to 0 sometimes. for broadcasting ? I change the behavior so that lvm will process_remote also on target_nodeid == 0
2. The joined_list passed to cpg_confchg_callback doesn't include the already exist nodes in the group, which leads to an incomplete node_hash. I simply add all other nodes in member_list to node_hash also.
Thanks to Xinwei Hu for this patch.
