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. -- cgit
