Not formally planned, there are bits and pieces out there (i.e. the inode mover) which are part of what it might take to achieve a shrinker. Another option, rather than fs shrinking, is to use the dm-thinp target, which would allow you to allocate a large-but-sparse block device, create a very large filesystem on that, and add or remove storage as needed. (At least I think you can remove it...!) -Eric > Thank you > S. _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
