Is there any way to remove entries in a CTDB cluster once they have been

then starting them back up?
Yes! You can use the undocumented dbwrap_tool.
USAGE: dbwrap_tool <database> <op> [<key> [<type> [<value>]]]
ops: fetch, store, delete, erase, listkeys, listwatchers
types: int32, uint32, string, hex
Example:
# list all the keys
dbwrap_tool yourdb.tdb listkeys
# remove the record by key
dbwrap_tool yourdb.tdb delete "name of the key"

Excellent - thanks Bjoern, I'll give that a go.
Worked perfectly - though I had to rebuild the sernet src rpm to get the
binaries, since they're not included in the rpm packages you guys build
(btw - thanks again for providing them!), but that was easy enough.
I also had slight confusion because the "listkeys" will spit out
"S-12345...-1234/00" and "GID 12345/00" - and it took me a while to
realise that I had to drop the "/00" part when calling the "delete".
Thanks again Björn - and everyone at Sernet :)
