if you can afford the hardware and the time for the copy, this would certainly be the best option... :) I've always done it that way as well. Lustre can be a scary upgrade and I've generally found that by the time I'm ready to update the machines the hardware has been abused for 2 or 3 years anyhow, so swapping out the hardware that's supporting a filesystem generally seemed like a good todo, certainly not a necessity though. my understanding (i haven't done it yet) is that the later versions of lustre >2.5 using zfs the upgrades have become more of a regular thing with much less concern. _______________________________________________ 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
