Re: [Samba] samba getting stuck, highwatermark replication issue?




Hi James,

Thanks for the quick reply.

You should be able to fix the 'replPropertyMetaData' errors with;

samba-tool dbcheck --cross-ncs --fix --yes 'fix_replmetadata_unsorted_attid'
Yep, worked great! Fixed all of those replPropertyMetaData errors! :-)

The highwatermark doesn't necessarily reflect an issue. It's part of how the destination DC keeps track of changes from the source DC. Can you verify the time and date is correct on all DC's?
Date & time matches. But the fact that the same identical message is logged multiple times per second, without an end seems a bit strange... Combined with high cpu usage on the DC where this happens. (yesterday DC2, currently on DC4)

The GUID errors seem related to your old DC offline and NTDS connections still lingering.  Open Microsoft Sites and Services and remove the ones no longer needed.
There is no DC1 mentioned anywhere there. And the two errors remain:

I was asked a question during the samba-tool dbcheck:

Add yourself to the replica locations for DC=DomainDnsZones,DC=samba,DC=company,DC=com? [y/N/all/none] N
Not fixing missing/incorrect attributes on DC=DomainDnsZones,DC=samba,DC=company,DC=com

Add yourself to the replica locations for DC=ForestDnsZones,DC=samba,DC=company,DC=com? [y/N/all/none] N
Not fixing missing/incorrect attributes on DC=ForestDnsZones,DC=samba,DC=company,DC=com

Should I answer Yes to those two questions?
