That doesn't sound like a lot to me, but instead of guessing around, let's just check the actual facts. Does "xfs_bmap -a" for the kind of files you are deleting show any extents? If it doesn't the output will look like: # xfs_bmap -a internal internal: no extents if it has any it will look like: # xfs_bmap -a external external: 0: [0..7]: 8557712..8557719 _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
