anyone else know for sure whether locking and client-side caching can be disabled on a per file basis?
What do *you* mean by locking and caching? Lustre is a POSIX compliant filesystem. This requires locking during systemcalls. These locks are cached on the client until revoked by a server. You could probably set the number of locks keept on the client to zero but this will kill performance. This setting is pr. filesystem not filelevel. fcntl locking is advisory locking of single files across systemcalls and is completely orthogonal to intra-systemcall locking. /Jakob _______________________________________________ Lustre-discuss mailing list [email protected] https://mail.clusterfs.com/mailman/listinfo/lustre-discuss
