A not runnning DNS service is a 7-crash. Another customer reported something similar with UCS 5.0-5 errata813. Create a Forward Zone with an included space character is possible with UMC. This resulted in a stopped bind service. snip from syslog (forward zone "Space Zone" on a test machine): Oct 12 13:56:18 mf2primary named[13978]: zone Space\032Zone/NONE: has 0 SOA records Oct 12 13:56:18 mf2primary named[13978]: zone Space\032Zone/NONE: has no NS records Oct 12 13:56:18 mf2primary named[13978]: samba_dlz: Failed to configure zone 'Space Zone' Oct 12 13:56:18 mf2primary named[13978]: loading configuration: bad zone Oct 12 13:56:18 mf2primary named[13978]: exiting (due to fatal error) Bug was reproducible with 5.0-5 errata830. We were in the situation that on a replica the DNS was down and not willing to start. So without DNS no replication -> the correction (deleting that zone spaces in the name) would not arrive on the replica. We switched to dns/backend=ldap and bind was willing to start again. We switched back to samba4 as dns/backend after the replication of the zone had arrived. Perhaps it helps others. |
