We have some content in AFS where it's acceptable to have a little bit of downtime, but we need to be able to recover with a minimum of hassle if we had an outage. In these cases, we mount the volumes explicitly as rw, but replicate them "behind the scenes" in cron. We can then use vos convertROtoRW if we need to quickly recover. It has its downsides, and it's not true multi-master RW, but it works in a pinch. - Ken ___ OpenAFS-info mailing list OpenAFS-info@openafs.org https://lists.openafs.org/mailman/listinfo/openafs-info
