Yup.

If space efficiency is a consideration then smaller blocksizes might be useful. Not so much for hits per day, but for how many files you expect to store at any one time; you'll waste ((blocksize / 2) * nr files) on average. -Eric _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
