> Does update only affect UFS operations? If I have nfs set to async, will > update sync it up? Update syncs dirty buffers for all mounted FS's. Unless NFS is mounted async (a violation of the RFC's defining the NFS protocol, for the most part), all ops will be synchronous anyway so that network outages do not leave implied state indeterminate. For example, a data file and a seperate index file which indexes records in the first file must be guaranteed colinear updating so that the database can be deterministically recovered following a client or server crash with a trasaction pending.
