I run in a similar problem in a test install recently, and I got better results that way. The bug is known to the DS people and they are working to get out patches that fix the root issue. Simo. </blockquote> CCing DS folks. Wasn't there a recent DS fix that was supposed to improve the RUV situation? Looking at 389 DS Trac, I see some interesting RUV fixes in 1.3.4.x releases: <a class="moz-txt-link-freetext" href="https://fedorahosted.org/389/query?summary=~RUV&status=closed&order=milestone&col=id&col=summary&col=status&col=owner&col=type&col=priority&col=milestone">https://fedorahosted.org/389/query?summary=~RUV&status=closed&order=milestone&col=id&col=summary&col=status&col=owner&col=type&col=priority&col=milestone</a> I see that 389-ds-base-1.3.4.3 is already in Fedora 22+, does the RUV issue happen there? </blockquote> it should not, and I think Thierry verified the fix. The problem we resolved and which we think is the core of the corrupted RUV was that the cleanallruv task did only purge the RUV, but dit not purge the changelog. If cleanallruv was run and the server had a disorderly shutdown (crash or abort when shutdown was hanging) then at restart the changelog RUV was rebuilt from the data in the changelog and if it contained a csn from cleaned RIDs this was added to the RUV (but the reference to the server was lost and so the url part is missing from this RUV. The fix now does remove all references to the cleaned RID from the changelog and the problem should not reoccur with RIDs cleaned with the fix, of course th echangelog can still can contain references to RIDs cleaned before the fix - and if no changelog trimming is configured this is what will happen. So, even after the fix old RUVs could pop up and have to be (finally) cleaned. The other source is that these corrupted rivs can be "imported" from another server by exchanging ruvs in the repl protocol. Cleanallruv tries to address this and to propagate the cleanallruv tasks to all servers it thinks are connected. If there are replication agreements to servers which no longer exist or to servers which cannot be connetcted this will delay the ruv cleaning </blockquote> Hello, I verified the fix in 1.3.4.2 F22 / 389-ds-base-1.3.4.0-6.el7 RHEL7, so after those versions CLEANALLRUV do not create any longer corrupted ruv elements. According to the timestamp in the ruv (for example csn2date.py 5587aa8d0003000e0000 --> 22/06/2015:06:26:21) this are old ruv elements. I think Ludwig is right, these corrupted ruv-elements come from old cleanallruv before the fix was applied. The problem is that even a fixed server can get those corrupted ruv-elements from others servers. All servers in the topology should be updated with that fix, so that at least they stop creating corrupted ruv-elements. Now to get rid of the existing ones, I imagine only brute option of recreating replica and reinit... I hope an other option is possible. thanks thierry </body> </html>
