Changes in CTDB 2.3
|
|
===================
|
|
|
|
User-visible changes
|
|
--------------------
|
|
|
|
* 2 new configuration variables for 60.nfs eventscript:
|
|
|
|
- CTDB_MONITOR_NFS_THREAD_COUNT
|
|
- CTDB_NFS_DUMP_STUCK_THREADS
|
|
|
|
See ctdb.sysconfig for details.
|
|
|
|
Important bug fixes
|
|
-------------------
|
|
|
|
* ctdb tool should not exit from a retry loop if a control times out
|
|
(e.g. under high load). This simple fix will stop an exit from the
|
|
retry loop on any error.
|
|
|
|
* When updating flags on all nodes, use the correct updated flags. This
|
|
should avoid wrong flag change messages in the logs.
|
|
|
|
* The recovery daemon will not ban other nodes if the current node
|
|
is banned.
|
|
|
|
Important internal changes
|
|
--------------------------
|
|
|
|
* The recovery daemon on stopped or banned node will stop participating in any
|
|
cluster activity.
|
|
|
|
|
|
Changes in CTDB 2.2
|
|
===================
|
|
|
|
User-visible changes
|
|
--------------------
|
|
|
|
* The "stopped" event has been removed.
|
|
|
|
The "ipreallocated" event is now run when a node is stopped. Use
|
|
this instead of "stopped".
|
|
|
|
* New --pidfile option for ctdbd, used by initscript
|
|
|
|
* The 60.nfs eventscript now uses configuration files in
|
|
/etc/ctdb/nfs-rpc-checks.d/ for timeouts and actions instead of
|
|
hardcoding them into the script.
|
|
|
|
* Notification handler scripts can now be dropped into /etc/ctdb/notify.d/.
|
|
|
|
* The NoIPTakeoverOnDisabled tunable has been renamed to
|
|
NoIPHostOnAllDisabled and now works properly when set on individual
|
|
nodes.
|
|
|
|
* New ctdb subcommand "runstate" prints the current internal runstate.
|
|
Runstates are used for serialising startup.
|
|
|
|
Important bug fixes
|
|
-------------------
|
|
|
|
* The Unix domain socket is now set to non-blocking after the
|
|
connection succeeds. This avoids connections failing with EAGAIN
|
|
and not being retried.
|
|
|
|
* Fetching from the log ringbuffer now succeeds if the buffer is full.
|
|
|
|
* Fix a severe recovery bug that can lead to data corruption for SMB clients.
|
|
|
|
* The statd-callout script now runs as root via sudo.
|
|
|
|
* "ctdb delip" no longer fails if it is unable to move the IP.
|
|
|
|
* A race in the ctdb tool's ipreallocate code was fixed. This fixes
|
|
potential bugs in the "disable", "enable", "stop", "continue",
|
|
"ban", "unban", "ipreallocate" and "sync" commands.
|
|
|
|
* The monitor cancellation code could sometimes hang indefinitely.
|
|
This could cause "ctdb stop" and "ctdb shutdown" to fail.
|
|
|
|
Important internal changes
|
|
--------------------------
|
|
|
|
* The socket I/O handling has been optimised to improve performance.
|
|
|
|
* IPs will not be assigned to nodes during CTDB initialisation. They
|
|
will only be assigned to nodes that are in the "running" runstate.
|
|
|
|
* Improved database locking code. One improvement is to use a
|
|
standalone locking helper executable - the avoids creating many
|
|
forked copies of ctdbd and potentially running a node out of memory.
|
|
|
|
* New control CTDB_CONTROL_IPREALLOCATED is now used to generate
|
|
"ipreallocated" events.
|
|
|
|
* Message handlers are now indexed, providing a significant
|
|
performance improvement.
