CTDB changes
------------
+* CTDB now uses a newly implemented parallel database recovery scheme
+ that avoids deadlocks with smbd.
+
+ In certain circumstances CTDB and smbd could deadlock. The new
+ recovery implementation avoid this. It also provides improved
+ recovery performance.
+
+* All files are now installed into and referred to by the paths
+ configured at build time. Therefore, CTDB will now work properly
+ when installed into the default location at /usr/local.
+
+* Public CTDB header files are no longer installed, since Samba and
+ CTDB are built from within the same source tree.
+
+* CTDB_DBDIR can now be set to tmpfs[:<tmpfs-options>]
+
+ This will cause volatile TDBs to be located in a tmpfs. This can
+ help to avoid performance problems associated with contention on the
+ disk where volatile TDBs are usually stored. See ctdbd.conf(5) for
+ more details.
+
* Configuration variable CTDB_NATGW_SLAVE_ONLY is no longer used.
Instead, nodes should be annotated with the "slave-only" option in
the CTDB NAT gateway nodes file. This file must be consistent
across nodes in a NAT gateway group. See ctdbd.conf(5) for more
details.
+* New event script 05.system allows various system resources to be
+ monitored
+
+ This can be helpful for explaining poor performance or unexpected
+ behaviour. New configuration variables are
+ CTDB_MONITOR_FILESYSTEM_USAGE, CTDB_MONITOR_MEMORY_USAGE and
+ CTDB_MONITOR_SWAP_USAGE. Default values cause warnings to be
+ logged. See the SYSTEM RESOURCE MONITORING CONFIGURATION in
+ ctdbd.conf(5) for more information.
+
+ The memory, swap and filesystem usage monitoring previously found in
+ 00.ctdb and 40.fs_use is no longer available. Therefore,
+ configuration variables CTDB_CHECK_FS_USE, CTDB_MONITOR_FREE_MEMORY,
+ CTDB_MONITOR_FREE_MEMORY_WARN and CTDB_CHECK_SWAP_IS_NOT_USED are
+ now ignored.
+
+* The 62.cnfs eventscript has been removed. To get a similar effect
+ just do something like this:
+
+ mmaddcallback ctdb-disable-on-quorumLoss \
+ --command /usr/bin/ctdb \
+ --event quorumLoss --parms "disable"
+
+ mmaddcallback ctdb-enable-on-quorumReached \
+ --command /usr/bin/ctdb \
+ --event quorumReached --parms "enable"
+
* The CTDB tunable parameter EventScriptTimeoutCount has been renamed
to MonitorTimeoutCount
@@ -58,6 +106,13 @@ CTDB changes
Configurations containing CTDB_SET_EventScriptTimeoutCount=<n> will
cause CTDB to fail at startup. Useful messages will be logged.
+* The commandline option "-n all" to CTDB tool has been removed.
+
+ The option was not uniformly implemented for all the commands.
+ Instead of command "ctdb ip -n all", use "ctdb ip all".
+
+* All CTDB current manual pages are now correctly installed
