| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As the basename of the script will be used for the readd script from setup_iface_ip_readd_script, it's know easier to identify what script is called by delete_ip_from_iface() while readding ips to the interface. metze (This used to be ctdb commit 3ee225b0b6ed37c22478bd145ced56b1b9b86842)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This combines the logic into a shell function which can be used by the "takeip" and "updateip" hooks. We check the return values of the "ip" commands now instead of ignoring them. We now create a setup_script.sh similar to the release_script.sh which makes it easier to analyze problems. metze (This used to be ctdb commit 624e8878851b4957cc7c02e922ec86926d6927ee)

| * | In ctdb_control_end_recovery,Ronnie Sahlberg2010-02-231-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We used to talloc_steal c (the command packet) and make it a child of the "event script state context". If we failed to create a eventscript child context for some reason, this would have talloc freed state, but at the same time it would also implicitely have freed c. Once ctdb_control_end_recovery() returns the error back to the caller, the caller would dereference both c, and also outdata which is a child of c and we would either read garbage data or segv. Change the ordering so we only talloc_steal c as a child of state IFF we have successfully created a child context for the script.

| * Leave sequence number alone when merely migrating records.Rusty Russell2010-02-161-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (Based on earlier version from Ronnie which modified tdb; this one is standalone). When storing records in a tdb that has "automatic seqnum updates" also check if the actual data for the record has changed or not. If it has not changed at all, except for possibly the header, this is likely just a dmaster migration operation in which case we want to write the record to the tdb but we do not want the tdb sequence number to be increased. This resolves the problem of notify.tdb being thrashed under load: the heuristic in smbd to only reread this when the sequence number increases (rarely) breaks down. Before, running nbench --num-progs=512 across 4 nodes, we saw numbers like: 512 1496 118.33 MB/sec execute 60 sec latency 0.00 msec And turning on latency tracking, this was typical in the logs: ctdbd: High latency 9380914.000000s for operation lockwait on database notify.tdb After this commit: 512 2451 143.85 MB/sec execute 60 sec latency 0.00 msec And no more latency messages...

For production systems with dedicated nas-heads we should never swap.

| | | | | | | | | | | | | | | | | | | | We can't just drop packets to the list, as those packets could be part of the core protocol the client is using. This happens (for example) when Samba is doing a traverse. If we drop a traverse packet then Samba hangs indefinately. We are better off dropping the ctdb socket to Samba.

| | | | | | | | | | | | | | | | | | | | | | | | The TLIST_*() macros are like the DLIST_*() macros, but take both a head and tail pointer for the list. This means that adding an element to the end of the list is efficient (it doesn't need to walk the list). We should move all uses of the DLIST_*() macros which use DLIST_ADD_END() to use the TLIST_*() macros instead. (This used to be ctdb commit 2d05a71349e9ade869b62cf261c2a9a21818a474)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | packets, to avoid the queue to grow excessively if smbd has blocked. This could cause traverse packets to become discarded in case the main smbd daemon does a traverse of a database while there is a recovery (sending a erconfigured message to smbd, causing an avalanche of unlock messages to be sent across the cluster.) This avalance of messages could cause also the tranversal message to be discarded causing the main smbd process to hang indefinitely waiting for the traversal message that will never arrive. Bump the maximum queue length before starting to discard messages from 1000 to 1000000 and at the same time rework the queueing slightly so we can append messages cheaply to the queue instead of walking the list from head to tail every time.
