And you can have a single zfs filesystem over 100s of nodes with petabytes of data? This thread has had a lot of mixing of single-node filesystems with cluster filesystems, it leads to a lot of confusion. Hadoop has checksums and maybe scrubbing, and the NoSQL database that we wrote at blekko has both plus end-to-end checksums; it's hard to imagine anyone writing a modern storage system without those features. -- greg _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
