Rapidly create and delete a tiny file 500 times -- will it use the same inode (metadata space) every time? Quite possibly. It picked a convenient location the first time, and the location remains convenient until something else snaps it up. On a busy filesystem it might juggle between a few nearby ones.

An old file on the other hand is liable to get boxed in, fragmented, difficult to expand -- less convenient. Delete those and it's harder for the system to find a good new use for those sectors.

So a recently deleted file is more likely to have its metadata overwritten than an old file just deleted. This of course isn't a rule however -- only true in statistical terms. Especially since exactly how a filesystem picks inodes and sectors depends on not just the exact operating system, but the exact filesystem and its tuning.

I don't find the results that amazing or hard to believe.

xfs_mdrestore

xfs_mdrestore(8)					      System Manager's Manual						  xfs_mdrestore(8)

NAME

       xfs_mdrestore - restores an XFS metadump image to a filesystem image

SYNOPSIS

       xfs_mdrestore [ -g ] source target

DESCRIPTION

       xfs_mdrestore  is  a debugging tool that restores a metadata image generated by xfs_metadump(8) to a filesystem. The source argument speci-
       fies the location of the metadump image and the target argument specifies the destination for the filsystem image.  If  the  source  is	-,
       then the metadata image is read from stdin. This allows the output of be another program such as a compression application to be redirected
       to xfs_mdrestore.  The target can be either a file or a device.

       xfs_mdrestore should not be used to restore metadata onto an existing filesystem unless you  are  completely  certain  the  target  can	be
       destroyed.

OPTIONS

       -g     Shows restore progress on stdout.

DIAGNOSTICS

       xfs_mdrestore returns an exit code of 0 if all the metadata is successfully restored or 1 if an error occurs.

SEE ALSO

       xfs_metadump(8), xfs_repair(8), xfs_check(8), xfs(5)

BUGS

       Email bug reports to xfs@oss.sgi.com.
