This this is a tool to handle (dump and convert) ctdb's local tdb
copies (ltdbs) without connecting to a ctdb daemon.
It can be used to
* dump the contents of a ltdb, printing
the ctdb record header information
* dump a non-clustered tdb database (like tdbdump)
* convert between an ltdb and a non-clustered tdb
(adding or removing ctdb headers)
* convert between 64 and 32 bit ltdbs
(the ctdb record headers differ by 4 bytes of padding)
usage: bin/ltdbtool dump [-p] [-s{0|32|64}] <idb>
bin/ltdbtool convert [-s{0|32|64}] [-o{0|32|64}] <idb> <odb>

Reduce an infomational message about not performing ip reallocation
from NOTICE(the default) to INFO.
These messages are normal during startup or when stopped/banned when
we will be in recovery mode for a while.
Remove a messager in the loop waiting for initial startup to complete about
the generation being invalid. It is always invalid at this stage before we have
finished initial recovery.
Rate-limit the informational messages for CTDB_WAIT_UNTIL_RECOVERED
so that we only print them once per second for the first 60 seconds and after that only once per 10 minutes.
These messages are normal during startup, but we should not be logging them every second for cases where we will remain in recovery mode during startup for an extended period of time.
Such as if suspended or permabanned.

we can not just check if MII Status is up for bonding mode 4, since the kernel will always report the bond device as UP
even if all cables are disconneccted.
For mode 4, ignore the status of the bond device and instead chek if at least one slave interface is up
when determining if the device is good or bad

Simplify the handling of setting the links in the 10.interface eventscript
and remove the optimization to only call setifacelink on state change
to make the code simpler to read.
If a take ip event fails, flag the node as unhealthy.
Add a check to the interface script to check if the interface exists
or if it has been deleted.
So that we can capture and become UNHELTHY if someone deletes an interface
we are using to host public addresses.

The init script does now check for the availability of tdbdump
and "tdbtool check" and issues warnings if they are not available.
This can remove a dependency loop with building samba RPMs.

Revert "ctdbd: call tdb_reopen_all() in freeze child."
This reverts commit 3d9828861c771a060923f3181fa8224e0122bffc.
(This used to be ctdb commit 55c3446c9ba82d24b1d7db92bc3611fd8027b7fb)
In theory, the ctdbd parent shouldn't be holding any locks, but it's a good
idea to always call tdb_reopen_all() after a fork().
(This used to be ctdb commit 3d9828861c771a060923f3181fa8224e0122bffc)
We should release the lock on the record before returning; otherwise the
recovery (which tries to freeze the database) will fail. Symptoms are as
follows:

This is to take advantage of the hash collision handling and logging
also in ctdb_local_schedule_for_deletion.
(This used to be ctdb commit 52193b6692091e341ed7a81dbd9a61ae49a8aac5)
Do not delete empty records that carry this flag but store
them and schedule them for deletetion. Do not store the flag
in the ltdb though, since this is internal only and should not
be visible to the client.
(This used to be ctdb commit f898ff21fa338358179e79381215b13a6bc77c53)
This is a flag that shall signa that a record has been automatically generated by ctdb
and not by an explicit client store operation. This will be used in the ctdb_ltdb_fetch
operation which stores an empty record with default initial header before trying to
migrate the record from the dmaster when the record does not exist in the local tdb.
(This used to be ctdb commit 46381a3cb58ccc11422af8f7798c80ea8d72294f)
When the record has been obtained by the lmaster as part of the vacuuming-fetch
handler and it is empty and never been migrated with data, then such records
are deleted instead of being stored. These records have automatically been
deleted when leaving the former dmaster, so that they vanish for good when
hitting the lmaster in this way. This will reduces the load on traditional
vacuuming.

When storing a record that is being migrated off to another node
and has never been migrated with data, then we can safely delete it
from the local tdb instead of storing the record with empty data.
Note: This record is not deleted if we are its lmaster or dmaster.

(This used to be ctdb commit 3cca0d4b48325d86de2cb0b44bb7811a30701352)
This is realized by adding a ctdb_ltdb_store_fn function pointer to the db
context and filling it in the attach procedure for non-persistent dbs.
(This used to be ctdb commit df49ec44de80affa5ccc637dec12a20a26e8706e)
This is supposed to contain logic for deleting records that are safe
to delete and scheduling records for deletion. It will be called in
server context for non-persistent databases instead of the standard
ctdb_ltdb_store() function.
