Hi folks,
I'm trying to delete an entry in the idmap database in a ctdb-managed
cluster, but I get:
"Could not remove gid to sid mapping"
when doing:
# wbinfo
--remove-gid-mapping=956781,S-1-5-21-861567501-1417001333-682003330-493603
Could not remove gid to sid mapping
or
# wbinfo
--set-gid-mapping=18400,S-1-5-21-861567501-1417001333-682003330-493603
Could not create or modify gid to sid mapping
Is there any way to remove entries in a CTDB cluster once they have been
created, short of shutting down all nodes, editing each tdb manually,
then starting them back up?
Cheers,
Orlando

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" Best regards Bj?rn -- SerNet GmbH, Bahnhofsallee 1b, 37081 G?ttingen phone: +49-551-370000-0, fax: +49-551-370000-9 AG G?ttingen, HRB 2816, GF: Dr. Johannes Loxen http://www.sernet.de, mailto:kontakt at sernet.de
