Is built in redundancy planned ? Or not in the scope of the project ? Steve
Trusting my 1.1Tb to the reliability of my drives, and touch wood in 20 years of computing had never had a drive fail.

Murali's explanation is spot-on: no software-based reduncancy scheme. For users concerned with redundancy, we suggest hardware failover to Shared storage, which works quite well. ==rob -- Rob Latham Mathematics and Computer Science Division A215 0178 EA2D B059 8CDF Argonne National Lab, IL USA B29D F333 664A 4280 315B _______________________________________________ Pvfs2-users mailing list [email protected] http://www.beowulf-underground.org/mailman/listinfo/pvfs2-users _______________________________________________ Pvfs2-users mailing list [email protected] http://www.beowulf-underground.org/mailman/listinfo/pvfs2-users
