I don't know how severe your situation was, but there's a similar situation that I discussed back in October. Here are two of the helpful answers to my question back then: https://lists.openafs.org/pipermail/openafs-info/2014-October/041085.html https://lists.openafs.org/pipermail/openafs-info/2014-October/041086.html I don't know if this helps to explain your situation, but note that the issue mentioned in my thread happens when *any* database server goes offline. -- Garance Alistair Drosehn = [email protected] Senior Systems Programmer or [email protected] Rensselaer Polytechnic Institute; Troy, NY; USA _______________________________________________ OpenAFS-info mailing list [email protected] https://lists.openafs.org/mailman/listinfo/openafs-info
