Although I've never seen any code or even a complete plan for it yet, recording the VG hierarchy information on disk would obviate the need for this scan. Doing this would allow you to salvage essentially instantly in most cases, so you might be able to recover from an unclean shutdown and salvage 100s of volumes in a few seconds. Again, not in 1.6, but it may happen soon enough as something to transition to away from fast-restart. -- Andrew Deason [email protected] _______________________________________________ OpenAFS-info mailing list [email protected] https://lists.openafs.org/mailman/listinfo/openafs-info
