I'm very good at producing bugs myself. But this code has run as is for years. The server was moved last weekend but I don't think there were any os changes. By the way, the sabotage line came from a user (ex submariner) that decided his bugs had to be sabotage. But considering that these files contain the processes pid to ensure they don't get overwritten by another instance of the process it would have to be someone jerking my chain if they were getting removed. We have a high priced unix consultant here that told me that sort with the redirection causes a seperate process to occur and the redirection is asyncronous so he thought that the move was happening before the redirection flushed the buffers. He suggested that I could add a sleep 1 or rm x before the move and probably never have the problem again. Gill

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
       xfs_mdrestore -V

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 filesystem 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.

       -V     Prints the version number and exits.

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.
