to be fair, nfs never was intended to really solve this problem. nfs just exports your existing storage. solutions to this "my disk is too small" problem have been around a while. ibm's jfs and lv are a good example (and dates back to around 1991). you can simply add new physical storage to an existing logical volume and grow the filesystem to use this new space. since then quite a few others have added these features. veritas has been around a little longer, but it has always been an extra you had to buy. irix, solaris and linux all now have similar features to ibm's lvm/jfs. there are some limits with this though--typically a 16T barrier somewhere. _______________________________________________ OpenAFS-info mailing list OpenAFS-info@openafs.org https://lists.openafs.org/mailman/listinfo/openafs-info
