I have a particular object in my LDAP database that is failing to
replicate (using syncrepl between two slapd's running 2.4.31-1+nmu2
on Debian Wheezy), despite other objects succeeding to replicate. I'm
not using a 'filter' configuration in my olcSyncrepl configuration
that might exclude this particular object, and I've checked that the
binddn I'm using has permission to see this object all the attributes
of the object that isn't replicating.
Any tips on how to further debug this?
corrupted file system?
I've checked access rules on the producer, and the account the consumer
is replicating with has access to the object in question. I've confirmed
the object doesn't exist on the consumer by reviewing the "slapcat"
output, it's not access rules preventing me seeing the object.
I hope I've avoided a corrupted file system or corrupted database, as
I"m seeing the same problem across multiple consumer VMs. At the same
time some older VMs (running Debian Squeeze, and slapd 2.4.23-7.3) are
not having this problem, which I think rules out corrupted filesystem or
database on the producer.
This information supports Quannah's observation that the problem is
probably the syncrepl bugs in 2.4.31.
I'm going to upgrade my consumer to the 2.4.40 backport that is now
available in Debian Wheezy, and see if the problem goes away (and
probably upgrade my producer likewise in my next maintenance window).
